Wisdom of the Crowd (2017) s01e03 Episode Script
Machine Learning
1 Hi, I'm Jeffrey Tanner.
Welcome to Sophe.
We all know the Internet changed the world.
The only question is: into what? It can be a platform to bring us together or to tear us apart.
I know, because I spent my life trying to turn it into something that would connect us all.
Then I love you, Dad.
my daughter was murdered.
Nothing else mattered anymore.
Everyone was sure they knew who did it the police, my ex-wife but I was convinced the wrong man had been convicted and the real killer was still out there.
So together with my team, I built Sophe, a crowdsource crime solving platform powered by the smartest, most diverse, independent collection of detectives on the planet: you.
Let's get to work.
Previously on Wisdom of the Crowd TANNER: I have evidence that leads me to believe the cops have incarcerated the wrong man.
This is not the kind of distraction that we need right now.
The more they start loving this, the more they're gonna start to believe that Jeffrey's actually right and Mia's killer is still out there.
You've been divorced nine years, you don't owe him anything.
TANNER: How can you be so sure that Carlos Ochoa wasn't the secret boyfriend? LORI: Because Carlos wasn't a secret.
- We've got something.
- About Mia? SARA: No, something new.
"Has anyone seen Antoine Reddick?" Is that blood?! We don't know anything for sure yet.
Can you please help us? - People are responding.
- He's alive.
We need paramedics, but he's alive.
(ALL CHEERING, WHOOPING) TANNER: Someone sent this photo.
Your daughter with some guy - who could be anybody.
- Or he could be the one walking out of her place the night she was murdered.
I checked all the arrests from Berkeley that night.
TANNER: Ryan Booth Same shirt as in the picture.
Tattoos match, too.
Can I put this on Sophe? Well, that's up to you.
(AIR BLOWING) Dude, you have got to be the most expensive data entry clerk in the Valley.
It's not data entry, it's data translation.
From what, hard copy to .
txt? These are old crime stats from the state archives.
See don't touch that every police department reports crime data in a different format.
Please stop.
So we've got to convert all of it to a uniform schema.
Luckily, it's something crowds are good at.
In fact, right now, I've got 2,187 users - helping with data verification - I take it back.
- and conversion.
- You're not just a clerk.
You are the king of all data entry.
What do we need with these old police reports, anyway? We are bootstrapping Sophe's machine learning.
By having her input crime data, her pattern-matching algorithms can analyze old cases, see if there's any links between Mia's murder and past crimes.
Then we feed those links back into the crowd for verification.
- It's like a perfect, symbio - (COMPUTER BEEPING) (JOSH TYPING) TARIQ: What? JOSH: It's saying these three cases are connected.
But they don't have anything to do with Mia.
Where's Tanner? He's dealing with something.
TANNER: Ryan Booth.
Did Mia ever mention anything about him to you? No, not that I can remember.
Why? TANNER: Mia's friend Lori Meyers said that Mia had a secret boyfriend.
Someone that she was scared of.
- That no one knew about.
- Mm-hmm.
I've gone through all the conversations that I've had with Mia a thousand times.
If she had said something to me about a person like this, I would've told the police.
I don't r I don't know - who this guy is.
- Okay, what about "sports shop"? "Sports" what? I don't Lori overheard Mia say that to him.
It could be a-a nickname, a place he worked.
Okay, Jeffrey.
- (SNIFFLES) - You need to stop this.
Please.
Listen to me, for as long as we've been divorced, I've always cared about you.
But you're spiraling right now.
- I'm spiraling? - You're s The police have caught our daughter's murderer.
- Carlos Ochoa? - Yeah.
No.
No.
I looked him in the eye in that prison, and that is not how he felt about Mia.
You went to visit Carlos Ochoa in prison? Because I needed to know the truth.
There isn't a part of you that doesn't wonder? Of course there is.
I miss her every single day.
And if I thought any of this were true, I would I would stand next to you, and I would tell the police they're wrong.
But they're not.
We looked at the crime scene photos.
Yeah.
Okay, we sat through the trial.
And we had to ID our daughter's body together.
Jeffrey, I can't keep reliving this anymore.
I am begging you to stop chasing ghosts.
This isn't a ghost.
This is a drug addict with a violent criminal record, caught on camera assaulting our daughter.
Honey And I am gonna find him.
CAVANAUGH: Yeah, that's right.
"Booth.
" B-O-O-T-H.
No, I'm looking for whatever you have.
He's a person of interest in a case down here.
So I was hoping that Yeah.
Yeah, of course I'll hold.
Again.
Working a case? You're a cop.
What does the evidence say? For us? Or are you moonlighting for Jeffrey Tanner again? H-Hello? Th nothing? Really? (SIGHS) Yeah, thank you.
Apparently, neither.
You do know your job is to take care of the cases on your desk, right? My job, Lieutenant, is to solve crimes.
And in case you forgot, Tanner's helped us take down two pretty big ones in the past week.
Look, Tommy, I'm just trying to help you out, okay? If the brass catch on that you're helping Jeffrey Tanner undermine a closed murder case Your closed murder case.
- Whatever.
- (PHONE BEEPS) I'm just saying.
Where are you going? To do my job.
It's been three days.
We still have nothing on Ryan Booth? It takes time.
If he's out there, we'll find him.
In the meantime, you're not gonna believe what Sophe's done.
- What? - Well we've been building out the system by having Sophe look at links between Mia's murder and past crimes.
And? Unfortunately, we didn't find any.
But we did find this.
Ten months ago, a woman named Mei Chang was murdered in an alley down in Hunters Point in San Francisco.
Two weeks later, Ramon Ortiz was found in a field in San Bruno.
A month after that, Olivia Medina was shot and killed over in Alameda.
The San Bruno and Alameda victims were both shot.
CBI linked the murders through ballistics, but Mei Chang, the Hunters Point victim, was suffocated.
SFPD ruled it as a random act of violence.
And I'm guessing that Sophe says otherwise.
Yeah.
Our cluster-weighted modeling engine inferred an 81% likelihood that all three cases are related.
SARA: And when we put it to the crowd to eliminate any coincidental overlaps, the links only got stronger.
Anyone notify the SFPD? SARA: I did.
Cavanaugh should be here any minute.
(WHIRRING) (CLICKS, WHIRRING STOPS) TANNER: Lemon-ginger-beet.
It'll clear your head.
You want some, Detective? I'm not a big beet guy, actually.
All right.
So what now, you guys are just gonna insert yourself into any open case you see fit? I thought you were looking for Ryan Booth.
We are.
But the Internet can multitask.
Every case that Sophe solves just makes her smart Yeah, smarter, yeah.
I know.
So good for Sophe, but I'm the one getting the dirty looks at work.
This isn't about me, Detective.
These victims are all the kinds of people who slip through the cracks: low income, minorities.
Justice isn't just supposed to be for people like me, is it? Oh, here we go.
Jeffrey Tanner, man of the people.
You're a pain in my ass.
I am acutely aware of that.
You got the case notes on the Mei Chang murder? Yeah.
Sure, I remember this case.
The investigating detective thought that was a carjacking gone bad.
But I remember thinking there was something more.
Josh, will you do me a favor? Will you pull up the woman in, um, Alameda? (TYPING) JOSH: Okay.
(TYPING) There.
There, look.
The victim's shoes were missing.
Just like Mei Chang.
What do you mean, "missing shoes"? I don't remember that from the official report, do you? - No, it wasn't in there.
- Uh, that could've been held back for investigative purposes.
Or possibly, whoever was typing it up got really lazy.
People wonder why I question the Carlos Ochoa murder.
Okay.
"Missing shoes.
" That should close the link between Mei Chang and Alameda.
Huh.
I thought it'd be higher.
CAVANAUGH: All right, what's happening? Detective, you don't just have three interconnected cases here.
- You've got, uh - Fourteen.
CAVANAUGH: What the hell? Are you saying all these cases are connected? I'm not.
Sophe is.
Like some sort of serial killer.
Post it.
Wha whoa, whoa, whoa.
Hold up, hold up.
- What? - Look, if you're right, the public might freak.
We got to think about how we're gonna do this.
- Done.
- What? Power to the people, am I right? Read 'em and weep.
What the hell, Tommy? You let Tanner take this thing live without vetting it first? I didn't let Tanner do anything.
Free speech.
If they want to cry "serial killer," there's not a whole lot I can do to stop them.
14 unrelated DBs? Yeah.
If this had been serial, someone would've noticed.
Actually, I'm not so sure.
I mean, spread over eight jurisdictions and 11 years.
I mean what these cases have in common are little bits of trace, minor background details.
Like the shoes, they must be trophies.
Most cases have them, but some cases don't.
They're all connected in tiny, different ways.
Kind of stuff even good cops would miss.
I know you like to obsess over your own cases, Tommy.
Now you want to obsess over everyone else's? Fine.
Where do we start? "We"? Deputy chief's orders.
If I didn't know better, I'd think she didn't trust you.
CAVANAUGH: Fine, let's start with the one in our jurisdiction.
Mei Chang.
WOMAN: You wouldn't even be here if it weren't for this Web site.
CAVANAUGH: Mrs.
Chang, I assure you that the SFPD remains committed to finding your daughter's killer.
I was looking through Mei's police file and it seems as though she had a bit of a troubled past, a few drug busts.
We did the best we could, but Maybe you see trouble, but this was our little girl.
Of course.
We think she may have worked with a man named Ramon Ortiz at Daly City Produce.
You know, they dated for a bit.
Uh, is he a suspect now? RUIZ: Ramon Ortiz is dead, Mr.
Chang.
He was one of the victims.
(SIGHS HEAVILY) At the funeral, Ramon pulled me to the side and he said he-he might have an idea who killed Mei.
When I never heard from him again, I figured he was just talking.
So, what do you think? Ortiz went looking for the killer and that's what got him shot? What I think is there's 13 more families out there just like this one.
And if a low-grade banger can find this guy, so can we.
TANNER: Three more unsolved murders.
- Yes.
- How the hell is that? User submissions.
The details haven't been uploaded to the statewide database yet.
Serial killer is sexy, so there is a flood of new registration.
That's bumping up our user base, big time.
TANNER: These have almost nothing in common with the first three murders.
Except the killer.
Uh, that's the thing with probabilistic graphing.
We're actually more certain of their interconnectedness because of the commonalities with the intermediate nodes.
Even I don't understand that.
- JOSH: Basically - The more cases come in, - the stronger the links get.
- Yeah.
Here's one the users found.
There were synthetic green fibers on half the victims and what appears to be latex burns - on several more.
- SARA: The challenge at the moment is trying to keep up with the rate of submissions.
What is it about serial killers that makes everyone want to play along at home? Stay on it.
Anything breaks, let me know.
I will.
Hear the news? I did not.
Hmm.
AllSourcer just named Nell DeGraf as their new CEO.
Nell DeGraf? She's a quant.
She's not a visionary.
She is asking for a sit-down.
She would like to pick your brain.
She's been handed the keys to a car she can't drive.
A parley with me isn't gonna fix it.
You left AllSourcer under less than ideal circumstances.
All right? The last thing we need right now is a fight.
With their user base and their market share thank you if they decided to actually drive traffic away from our site, - we're looking at a - All right, all right, whatever.
I'll sit down.
(SIGHS) And you'll, you'll-you'll promise to be pleasant? Am I ever unpleasant, Mike? Don't speak.
GUARD: Keep it moving, keep it moving.
This is for that white girl.
Hey, Carlos, relax.
Relax.
Calm down, man.
Listen, you want protection in here, homie, you stick with your own kind, all right? You just stay at my car, nothing's gonna happen to you.
I'll take care of you, man.
Let's go.
Sara.
Hmm? Can I borrow you for a second? Sure.
What do you need? What do we have on that sports shop clue? Um, as of this moment, 836 distinct hypotheses.
Give me.
(EXHALES) What are you thinking? Well, that if you can Where's Waldo? - a serial killer out of thin air - Mm.
you can link one of our sports shop clues to Ryan Booth.
Let me drive.
Let a professional take the wheel.
(CLEARS THROAT) What? Nothing, nothing.
I just, I like the way you code.
SARA: Right.
(CLEARS THROAT) - TANNER: Yes.
- SARA: So number one match is a sporting goods store called The Sport Stop, 16 miles from Mia's apartment.
Probability of connection to Ryan Booth is (SIGHS) - 0.
015%.
- Oh.
The next match is half that.
This man is a ghost.
Yeah, that seems to be the consensus.
MIKE: Uh (CLEARS THROAT) Excuse me, guys.
Um, I just got a call from security.
There's somebody here you're gonna want to meet.
Who's that? It's Ryan Booth's brother.
MAN: You had no right.
You had no right to plaster Ryan's face - all over your Web site.
- All right, Mr.
Booth, I understand that you want to protect your brother, just (CHUCKLES) Protect him? My brother sucked up every resource my family had.
My dad took out a second mortgage just to send him to Grand Pines.
Grand Pines? Some fancy treatment center.
Look, six weeks after Ryan graduated, he got nailed for another DUI.
Where is he now? I don't know.
We cut contact after his last relapse.
And you stuck your nose in and you ripped that wound right open.
If you have any humanity at all, you will take his picture down and let this go.
I can't do that.
That figures.
The shrink told Ryan he had narcissistic personality disorder.
Said his brain was so consumed with the next fix that anybody standing in his way was just collateral damage.
That sound like anyone you know? (QUIETLY): All right.
All right, thank you.
Come on.
I take it he isn't going to help.
Oh, no, he-he wants me to die in a fire.
But, on the bright side, he mentioned that his brother was a patient at a place called Grand Pines.
Okay.
Well, that's another potential link.
It's actually better than that.
Mia's program at Berkeley was affiliated with that hospital and that's how they met.
It all makes sense.
JOSH: because it wasn't a murder.
It should be easy for you.
You're a wizard, Harry.
Okay, that's really cute.
I'm gonna call Cavanaugh and let him know.
Go ahead, call Cavanaugh.
Let him know what? Uh we have another victim.
But this one's alive.
I was training for a marathon.
Uh, you know, bad breakups and whatever.
Um, it was pretty late.
I was working long hours back then.
I had just finished my run and, uh, I ducked in to get a bottle of water.
There was a there used to be a convenience store there on the corner.
But they've torn this whole block down.
So, you come out and you head Uh, back towards my house.
And then the next thing I know, there's a, uh there's a-a plastic bag over my head.
And, um, he's trying to get me down on the ground.
Take your time.
It it was the gloves.
When I read on Sophe that some of the victims had friction burns from the latex, that's when I knew it was the same guy.
Did you see his face? It was dark.
But I remember that he smelled like strawberries.
Not the real kind, the, um sickly sweet medicine kind, like the the artificial kind.
Um and then I fought him off.
(TAKES DEEP BREATH) I don't know how.
I kicked, I fought, I I just ran.
As tired as my legs were, I ran all the way home.
But, you know, I haven't run since.
Every day I just stare at those shoes, and I can't.
We're gonna get this guy, Ms.
Vincent.
I promise you that.
- Mr.
Tanner, I've already told you - Yes? That due to the HIPPA regulation, I know, you already Yes.
I cannot divulge information regarding any patient who may or may not have - been treated at this facility.
- Will you listen? - The door's right here, sir.
- We, uh, we - we both we both know - Not here, not now.
that Ryan Booth was a patient here at this facility.
Okay, I understand that you have these laws to protect people, and I get it and I respect that.
My daughter was was 22 years old, and she could have done whatever she wanted with her life.
And she chose to devote herself to helping others.
And she volunteered here.
That has to account for something.
Mr.
Tanner, I am sorry for your loss.
I truly am.
But I'm afraid there is nothing I can do, and you must go.
Have a good day, sir.
Mr.
Tanner.
I'm a huge fan.
I actually met my partner in a AllSourcer chat group "Quidditch Quorum.
" Are you still looking for Ryan Booth? Did you know him? Oh, no, he was way before my time.
But when I saw on Sophe you were looking for him, it reminded me of something.
I found it cleaning out the art room.
One of the other nurses said that Ryan Booth made it.
I guess he made one for everybody.
I was gonna write in, but I didn't want to get in trouble.
Did I help? More than you know.
Thank you.
Yeah.
(CAMERA SHUTTER CLICKS) (NO AUDIO) Zwart Schaap.
(NO AUDIO) MAN'S VOICE: Zwart Schaap.
CARLOS: No, he can't call me back.
I told you, because I'm in Never mind, just tell him that it's an emergency.
(QUIETLY): Tell him I might know who killed Mia Tanner.
What's up? You, uh, get everything you need, or No.
Not yet.
This is pointless.
17 murders and an attempted murder, and they're all over the place.
Physical evidence is different form victim to victim.
I mean, this one had latex burns but no fiber.
This one has fiber, no latex.
Cause of death for most of them is asphyxiation, except for these three, they were shot.
Some of the bodies are left at the scene, Some are traveled and dumped.
And what does the smell of strawberries have to do with any of it? He's out there.
The sick bastard that did all this is still out there.
If it was any other case, we'd be looking for geographic similarities.
Look at this map.
Here.
This is the corner where Miranda Vincent was attacked.
Not only is the convenience store not there, but this alley is supposed to be right next to it.
That's not there, either.
Yeah, I know.
The whole region has changed.
Some of these maps are too old, but some are too new.
How are we supposed to find similarities if we don't know what the area looked like when the murders went down? I have an idea.
Where are you going? We are going down the rabbit hole.
(INDISTINCT CHATTER) Lieutenant Ruiz.
Glad you finally figured out that we can help.
Believe me, this wasn't my idea.
Well, you just leave the ideas to us.
I think those together would be great.
Hey, so, um, it took a little doing, but between construction permits and city change orders, we managed to reconstruct what the neighborhoods would have been like at the exact date - of each of the attacks.
- You can do that? I've always wondered, do police phones have buttons now or is it still that old rotary-dial-type Ignore him.
As I was saying, we discovered an interesting trend.
Yes.
Each of these neighborhoods was undergoing rapid redevelopment at the time these murders occurred.
Can you see that? CAVANAUGH: Construction.
TANNER: Yeah.
- Mm-hmm.
- It's not that the neighborhoods changed.
It's the construction itself.
- Exactly.
- Precisely.
At the time of each of the murders, there was an active construction site within three blocks of where the body was found.
That might explain the trace minerals we found on some of the bodies.
We're looking for someone who worked - at every one of these sites.
- Mm-hmm.
Find him, and you'll find your killer.
Thank you.
So, Jeffrey, I'll get right to the point.
I think the board was crazy to let you walk out the door with Sophe.
We both know crowdsourcing is the next evolution in social networks.
I want AllSourcer in on the action.
And they said you weren't a visionary.
- (MIKE CHUCKLES) - Look at that.
(CHUCKLES) - Right? - I think I think I think, actually, what Jeffrey means - Look, uh - is that he's looking I-I spent the better part of a year trying to get Sophe away from AllSourcer.
Why would I want to put her right back in? Well, I understand you're having some cash flow issues.
Word gets around.
You know, we're willing to make a substantial investment that will enable you to grow Sophe organically.
And all I ask in return is access to Sophe's underlying I.
P.
The I.
P.
that I specifically carved out before I left? (CHUCKLES) Why No, I'm sorry, why would I want to do that? Or I could just wait for you to fail and then pick up - the pieces.
- Ah, see, I thought this was gonna be a hostile takeover.
I was completely wrong.
It's a passive-aggressive one.
MIKE: Look, maybe there's a way that we can arrange a mutually beneficial partnership.
Look, the-the problem with any partnership is there are strings attached.
The only way, moving forward, to make AllSourcer whole is to monetize Sophe.
So making money is a problem now? What Sophe is about is people wanting to be a part of something bigger than themselves.
Yes, I understand that, Jeffrey, - but I don't think you understand - (PHONE CHIMES) what I'm offering here.
I have to take this.
- I got to go.
- The You're gonna go? Jeffrey, where What do you think Jeffrey.
So, we combed through the official records, but we couldn't find any one worker who was ever at more than a few of the locations.
But you've got subcontractors and off-the-book workers.
Exactly.
That's where our users come in.
Yeah, we've got photographs and all kinds of documentation coming in on all 17 construction sites.
Uh, what's with all the flashing? User input.
People are highlighting regions for analysis.
SARA: They're trying to find common elements in the photos.
So, one user selects an item, and then the others weigh in on whether it seems relevant or not.
Wouldn't a computer be faster? Mm.
Visual comprehension is actually one of those things that's better done by humans than by microchips.
It's not elegant, but intuition plays a big part.
- (BEEPS) - And we have a match.
"Ever-Fresh Sanitation Services.
" How's portable outhouses for a link? (GASPS) That strawberry smell.
- Deodorizer.
- Yeah.
TARIQ: A company like this, they probably have a dozen open construction sites right now.
CAVANAUGH: Then we better hurry.
Send the address to my phone.
We'll get it on the way.
Damn it, Jeffrey, that was her asking nice, okay? The next offer is going to come across some lawyer's table.
So just Just call me back.
Where the hell is he? He's not with you? No.
He pulled a Houdini on lunch.
He got some text, then just took off.
Oh, that might have been me.
Yeah, some user in Cleveland tracked down that wire sculpture Tanner posted on Sophe.
Said he bought one online a couple months ago.
Return address was up in Guerneville somewhere.
Guerneville? (ENGINE REVS) RYAN: I didn't kill your daughter.
I knew you were looking for me.
I'm not a total hermit.
But I'm not the guy.
Not the guy that killed my daughter? Put the axe down.
Put it down.
I'm not the guy.
The night Mia died, I was on day three of a two-week intensive care stay.
I got a stack of bills inside I could show you.
They're still trying to collect on them.
Then why? Why what? Why were you grabbing her arm in the photo? Why don't you have a seat? Here you go.
I was crazy about her.
Completely unrequited, might I add.
Hell, anyone who met her was.
There was a party the night of the protest.
I knew she'd be there, so I showed up.
I was messed up by the time I found her.
Drunk, high, whatever else you can think of.
(LAUGHS SOFTLY) Uh, she read me the Riot Act.
Wanted me to call my sponsor, you know, go to a meeting.
Even as mad as she was, she always wanted to do the right thing.
I grabbed her.
I'm not proud of that.
I was just trying to convince her to come home with me.
She didn't.
(CHUCKLES) You'd be proud.
Man.
It's a hell of a thing, pissing off the nicest person you ever knew.
She wouldn't even let me visit her at work.
She said that, uh, she thought it might be distracting if everyone knew that she was Jeffrey Tanner's daughter.
(CHUCKLES) Yeah.
Did you see much of her, at Grand Pines? What she was like with the doctors and the patients? 'Cause I know that interning is like 90% coffee and paperwork, but she must have left an impression.
Oh.
Um Mr.
Tanner.
Mia wasn't an intern at Grand Pines.
She was a patient.
She was She was a what? Checked in the same day as me.
She said, you know, he was depressed and needed to get her head straight.
Well if he has any more dead bodies, we sure won't smell them.
(CREAKING) Well, hello.
Don't get many walk-ins around here.
Byron O'Malley? You can call me B.
J.
, sweetheart.
You, uh, want to rent some units? San Francisco Police.
Oh.
- Keep your hands where I can see them.
- Oh, no, I I'm not much of a threat.
Come on in.
(GRUNTS) Come on.
You're, uh Y'all acting kind of jumpy, aren't you? Business records indicate that you're the sole proprietor.
Is that correct? - Sure.
- One of your workers might know something about a criminal matter.
Well, you're gonna have to be more specific.
Um, I've got guys coming and going all the time.
CAVANAUGH: Uh, someone who's worked here for 12 years or more.
Uh, there's only one guy been there that long.
Don Farrel.
What's Donnie done now? Well, you tell us where we can find him, and we'll see.
Well, you're not gonna have to go far.
He's right here.
RUIZ (WHISPERS): Tommy.
Where's he going? CAVANAUGH: Police! Give yourself up, Farrel! (CLATTERING) Police! Stop! RUIZ (OVER RADIO): There's a room in the back.
I got him.
(THUDDING) San Francisco Police.
Show me your hands.
Show me your hands now! I'd do what he says.
Interlace your fingers behind your head.
Hurry up.
What took you so long? (HANDCUFFS CLICKING) SARA: He was trying to dispose of the shoes in a vat of acid.
Machine learning, baby.
How's that for the power of math? TARIQ: Uh, not so fast there, Archimedes.
My photo-matching software found those toilets.
I broke the case.
Q.
E.
D.
, move, I push the button.
Uh, you wouldn't have even known where to look if it weren't for Sophe.
And that's not the correct use of "Q.
E.
D.
" - That is the correct use of Q.
E.
D.
- You don't even know what it stands for.
Calm down.
What does it stand for? You're both pretty.
Nice one.
Josh.
REPORTER: This seemingly innocent warehouse hid the secrets of a man police believe is responsible for 17 deaths in the Bay Area over the past 12 years.
(CAMERA CLICKING, BEEPING) ALEX: Perfect.
- I think we have it.
Okay, wonderful.
- Thank you.
See you gentlemen soon.
Can I just ask you to wait outside for a moment? I just need You knew, didn't you? Knew what? About Mia's stay at Grand Pines.
Jeffrey Of course you did.
You had to pay for it.
What are you talking about? I found Ryan Booth.
He didn't kill her.
But he and Mia were patients together - at Grand Pines.
- Wait a minute.
- Unbeknownst to me - Okay, hold on a second.
- That's what this whole thing - So yes.
- Is about, Jeffrey? - Why didn't you tell me? I couldn't tell you, Jeffrey.
Mia was an adult at the time; she was 20 years old.
And she didn't want anyone to know.
- She didn't want you to know.
- I could've helped her.
No, you couldn't have.
Jeffrey.
I'm not even I'm not even mad at you.
I'm mad at myself because I keep getting sucked in.
Just a moment.
It's just (SIGHS) You're gonna kill me if you don't let this go.
And you're gonna end up killing yourself.
TANNER: What if we never find him? What-what if I am just, really chasing ghosts? Then we'll learn that together.
Okay? The tech works.
I mean, an hour ago, we just pulled a serial killer off the street.
Yeah.
We're gonna find the truth about Mia.
Okay? Hey, hey, hey, hey.
We solved AllSourcer's reboot algorithm - with 12 hours - Mm-hmm.
a whiteboard, and, from what I remember, - was contaminated moo shu pork.
- (LAUGHS) Yeah.
- It was disgusting.
- It was.
We've got this.
Okay? Yeah.
(METAL DOOR CLATTERING, CLOSING) (WATER RUNNING) (GRUNTS) (WATER STOPS RUNNING) (EXHALES) Man, I thought they was gonna throw down back there, man.
(SCOFFS) I told you.
You stick with us, you stay protected.
Man, thanks, homie.
- (SLICES) - (CARLOS GRUNTS) You should've just kept your mouth shut about that girl.
(WHEEZING) (LABORED BREATHING)
Welcome to Sophe.
We all know the Internet changed the world.
The only question is: into what? It can be a platform to bring us together or to tear us apart.
I know, because I spent my life trying to turn it into something that would connect us all.
Then I love you, Dad.
my daughter was murdered.
Nothing else mattered anymore.
Everyone was sure they knew who did it the police, my ex-wife but I was convinced the wrong man had been convicted and the real killer was still out there.
So together with my team, I built Sophe, a crowdsource crime solving platform powered by the smartest, most diverse, independent collection of detectives on the planet: you.
Let's get to work.
Previously on Wisdom of the Crowd TANNER: I have evidence that leads me to believe the cops have incarcerated the wrong man.
This is not the kind of distraction that we need right now.
The more they start loving this, the more they're gonna start to believe that Jeffrey's actually right and Mia's killer is still out there.
You've been divorced nine years, you don't owe him anything.
TANNER: How can you be so sure that Carlos Ochoa wasn't the secret boyfriend? LORI: Because Carlos wasn't a secret.
- We've got something.
- About Mia? SARA: No, something new.
"Has anyone seen Antoine Reddick?" Is that blood?! We don't know anything for sure yet.
Can you please help us? - People are responding.
- He's alive.
We need paramedics, but he's alive.
(ALL CHEERING, WHOOPING) TANNER: Someone sent this photo.
Your daughter with some guy - who could be anybody.
- Or he could be the one walking out of her place the night she was murdered.
I checked all the arrests from Berkeley that night.
TANNER: Ryan Booth Same shirt as in the picture.
Tattoos match, too.
Can I put this on Sophe? Well, that's up to you.
(AIR BLOWING) Dude, you have got to be the most expensive data entry clerk in the Valley.
It's not data entry, it's data translation.
From what, hard copy to .
txt? These are old crime stats from the state archives.
See don't touch that every police department reports crime data in a different format.
Please stop.
So we've got to convert all of it to a uniform schema.
Luckily, it's something crowds are good at.
In fact, right now, I've got 2,187 users - helping with data verification - I take it back.
- and conversion.
- You're not just a clerk.
You are the king of all data entry.
What do we need with these old police reports, anyway? We are bootstrapping Sophe's machine learning.
By having her input crime data, her pattern-matching algorithms can analyze old cases, see if there's any links between Mia's murder and past crimes.
Then we feed those links back into the crowd for verification.
- It's like a perfect, symbio - (COMPUTER BEEPING) (JOSH TYPING) TARIQ: What? JOSH: It's saying these three cases are connected.
But they don't have anything to do with Mia.
Where's Tanner? He's dealing with something.
TANNER: Ryan Booth.
Did Mia ever mention anything about him to you? No, not that I can remember.
Why? TANNER: Mia's friend Lori Meyers said that Mia had a secret boyfriend.
Someone that she was scared of.
- That no one knew about.
- Mm-hmm.
I've gone through all the conversations that I've had with Mia a thousand times.
If she had said something to me about a person like this, I would've told the police.
I don't r I don't know - who this guy is.
- Okay, what about "sports shop"? "Sports" what? I don't Lori overheard Mia say that to him.
It could be a-a nickname, a place he worked.
Okay, Jeffrey.
- (SNIFFLES) - You need to stop this.
Please.
Listen to me, for as long as we've been divorced, I've always cared about you.
But you're spiraling right now.
- I'm spiraling? - You're s The police have caught our daughter's murderer.
- Carlos Ochoa? - Yeah.
No.
No.
I looked him in the eye in that prison, and that is not how he felt about Mia.
You went to visit Carlos Ochoa in prison? Because I needed to know the truth.
There isn't a part of you that doesn't wonder? Of course there is.
I miss her every single day.
And if I thought any of this were true, I would I would stand next to you, and I would tell the police they're wrong.
But they're not.
We looked at the crime scene photos.
Yeah.
Okay, we sat through the trial.
And we had to ID our daughter's body together.
Jeffrey, I can't keep reliving this anymore.
I am begging you to stop chasing ghosts.
This isn't a ghost.
This is a drug addict with a violent criminal record, caught on camera assaulting our daughter.
Honey And I am gonna find him.
CAVANAUGH: Yeah, that's right.
"Booth.
" B-O-O-T-H.
No, I'm looking for whatever you have.
He's a person of interest in a case down here.
So I was hoping that Yeah.
Yeah, of course I'll hold.
Again.
Working a case? You're a cop.
What does the evidence say? For us? Or are you moonlighting for Jeffrey Tanner again? H-Hello? Th nothing? Really? (SIGHS) Yeah, thank you.
Apparently, neither.
You do know your job is to take care of the cases on your desk, right? My job, Lieutenant, is to solve crimes.
And in case you forgot, Tanner's helped us take down two pretty big ones in the past week.
Look, Tommy, I'm just trying to help you out, okay? If the brass catch on that you're helping Jeffrey Tanner undermine a closed murder case Your closed murder case.
- Whatever.
- (PHONE BEEPS) I'm just saying.
Where are you going? To do my job.
It's been three days.
We still have nothing on Ryan Booth? It takes time.
If he's out there, we'll find him.
In the meantime, you're not gonna believe what Sophe's done.
- What? - Well we've been building out the system by having Sophe look at links between Mia's murder and past crimes.
And? Unfortunately, we didn't find any.
But we did find this.
Ten months ago, a woman named Mei Chang was murdered in an alley down in Hunters Point in San Francisco.
Two weeks later, Ramon Ortiz was found in a field in San Bruno.
A month after that, Olivia Medina was shot and killed over in Alameda.
The San Bruno and Alameda victims were both shot.
CBI linked the murders through ballistics, but Mei Chang, the Hunters Point victim, was suffocated.
SFPD ruled it as a random act of violence.
And I'm guessing that Sophe says otherwise.
Yeah.
Our cluster-weighted modeling engine inferred an 81% likelihood that all three cases are related.
SARA: And when we put it to the crowd to eliminate any coincidental overlaps, the links only got stronger.
Anyone notify the SFPD? SARA: I did.
Cavanaugh should be here any minute.
(WHIRRING) (CLICKS, WHIRRING STOPS) TANNER: Lemon-ginger-beet.
It'll clear your head.
You want some, Detective? I'm not a big beet guy, actually.
All right.
So what now, you guys are just gonna insert yourself into any open case you see fit? I thought you were looking for Ryan Booth.
We are.
But the Internet can multitask.
Every case that Sophe solves just makes her smart Yeah, smarter, yeah.
I know.
So good for Sophe, but I'm the one getting the dirty looks at work.
This isn't about me, Detective.
These victims are all the kinds of people who slip through the cracks: low income, minorities.
Justice isn't just supposed to be for people like me, is it? Oh, here we go.
Jeffrey Tanner, man of the people.
You're a pain in my ass.
I am acutely aware of that.
You got the case notes on the Mei Chang murder? Yeah.
Sure, I remember this case.
The investigating detective thought that was a carjacking gone bad.
But I remember thinking there was something more.
Josh, will you do me a favor? Will you pull up the woman in, um, Alameda? (TYPING) JOSH: Okay.
(TYPING) There.
There, look.
The victim's shoes were missing.
Just like Mei Chang.
What do you mean, "missing shoes"? I don't remember that from the official report, do you? - No, it wasn't in there.
- Uh, that could've been held back for investigative purposes.
Or possibly, whoever was typing it up got really lazy.
People wonder why I question the Carlos Ochoa murder.
Okay.
"Missing shoes.
" That should close the link between Mei Chang and Alameda.
Huh.
I thought it'd be higher.
CAVANAUGH: All right, what's happening? Detective, you don't just have three interconnected cases here.
- You've got, uh - Fourteen.
CAVANAUGH: What the hell? Are you saying all these cases are connected? I'm not.
Sophe is.
Like some sort of serial killer.
Post it.
Wha whoa, whoa, whoa.
Hold up, hold up.
- What? - Look, if you're right, the public might freak.
We got to think about how we're gonna do this.
- Done.
- What? Power to the people, am I right? Read 'em and weep.
What the hell, Tommy? You let Tanner take this thing live without vetting it first? I didn't let Tanner do anything.
Free speech.
If they want to cry "serial killer," there's not a whole lot I can do to stop them.
14 unrelated DBs? Yeah.
If this had been serial, someone would've noticed.
Actually, I'm not so sure.
I mean, spread over eight jurisdictions and 11 years.
I mean what these cases have in common are little bits of trace, minor background details.
Like the shoes, they must be trophies.
Most cases have them, but some cases don't.
They're all connected in tiny, different ways.
Kind of stuff even good cops would miss.
I know you like to obsess over your own cases, Tommy.
Now you want to obsess over everyone else's? Fine.
Where do we start? "We"? Deputy chief's orders.
If I didn't know better, I'd think she didn't trust you.
CAVANAUGH: Fine, let's start with the one in our jurisdiction.
Mei Chang.
WOMAN: You wouldn't even be here if it weren't for this Web site.
CAVANAUGH: Mrs.
Chang, I assure you that the SFPD remains committed to finding your daughter's killer.
I was looking through Mei's police file and it seems as though she had a bit of a troubled past, a few drug busts.
We did the best we could, but Maybe you see trouble, but this was our little girl.
Of course.
We think she may have worked with a man named Ramon Ortiz at Daly City Produce.
You know, they dated for a bit.
Uh, is he a suspect now? RUIZ: Ramon Ortiz is dead, Mr.
Chang.
He was one of the victims.
(SIGHS HEAVILY) At the funeral, Ramon pulled me to the side and he said he-he might have an idea who killed Mei.
When I never heard from him again, I figured he was just talking.
So, what do you think? Ortiz went looking for the killer and that's what got him shot? What I think is there's 13 more families out there just like this one.
And if a low-grade banger can find this guy, so can we.
TANNER: Three more unsolved murders.
- Yes.
- How the hell is that? User submissions.
The details haven't been uploaded to the statewide database yet.
Serial killer is sexy, so there is a flood of new registration.
That's bumping up our user base, big time.
TANNER: These have almost nothing in common with the first three murders.
Except the killer.
Uh, that's the thing with probabilistic graphing.
We're actually more certain of their interconnectedness because of the commonalities with the intermediate nodes.
Even I don't understand that.
- JOSH: Basically - The more cases come in, - the stronger the links get.
- Yeah.
Here's one the users found.
There were synthetic green fibers on half the victims and what appears to be latex burns - on several more.
- SARA: The challenge at the moment is trying to keep up with the rate of submissions.
What is it about serial killers that makes everyone want to play along at home? Stay on it.
Anything breaks, let me know.
I will.
Hear the news? I did not.
Hmm.
AllSourcer just named Nell DeGraf as their new CEO.
Nell DeGraf? She's a quant.
She's not a visionary.
She is asking for a sit-down.
She would like to pick your brain.
She's been handed the keys to a car she can't drive.
A parley with me isn't gonna fix it.
You left AllSourcer under less than ideal circumstances.
All right? The last thing we need right now is a fight.
With their user base and their market share thank you if they decided to actually drive traffic away from our site, - we're looking at a - All right, all right, whatever.
I'll sit down.
(SIGHS) And you'll, you'll-you'll promise to be pleasant? Am I ever unpleasant, Mike? Don't speak.
GUARD: Keep it moving, keep it moving.
This is for that white girl.
Hey, Carlos, relax.
Relax.
Calm down, man.
Listen, you want protection in here, homie, you stick with your own kind, all right? You just stay at my car, nothing's gonna happen to you.
I'll take care of you, man.
Let's go.
Sara.
Hmm? Can I borrow you for a second? Sure.
What do you need? What do we have on that sports shop clue? Um, as of this moment, 836 distinct hypotheses.
Give me.
(EXHALES) What are you thinking? Well, that if you can Where's Waldo? - a serial killer out of thin air - Mm.
you can link one of our sports shop clues to Ryan Booth.
Let me drive.
Let a professional take the wheel.
(CLEARS THROAT) What? Nothing, nothing.
I just, I like the way you code.
SARA: Right.
(CLEARS THROAT) - TANNER: Yes.
- SARA: So number one match is a sporting goods store called The Sport Stop, 16 miles from Mia's apartment.
Probability of connection to Ryan Booth is (SIGHS) - 0.
015%.
- Oh.
The next match is half that.
This man is a ghost.
Yeah, that seems to be the consensus.
MIKE: Uh (CLEARS THROAT) Excuse me, guys.
Um, I just got a call from security.
There's somebody here you're gonna want to meet.
Who's that? It's Ryan Booth's brother.
MAN: You had no right.
You had no right to plaster Ryan's face - all over your Web site.
- All right, Mr.
Booth, I understand that you want to protect your brother, just (CHUCKLES) Protect him? My brother sucked up every resource my family had.
My dad took out a second mortgage just to send him to Grand Pines.
Grand Pines? Some fancy treatment center.
Look, six weeks after Ryan graduated, he got nailed for another DUI.
Where is he now? I don't know.
We cut contact after his last relapse.
And you stuck your nose in and you ripped that wound right open.
If you have any humanity at all, you will take his picture down and let this go.
I can't do that.
That figures.
The shrink told Ryan he had narcissistic personality disorder.
Said his brain was so consumed with the next fix that anybody standing in his way was just collateral damage.
That sound like anyone you know? (QUIETLY): All right.
All right, thank you.
Come on.
I take it he isn't going to help.
Oh, no, he-he wants me to die in a fire.
But, on the bright side, he mentioned that his brother was a patient at a place called Grand Pines.
Okay.
Well, that's another potential link.
It's actually better than that.
Mia's program at Berkeley was affiliated with that hospital and that's how they met.
It all makes sense.
JOSH: because it wasn't a murder.
It should be easy for you.
You're a wizard, Harry.
Okay, that's really cute.
I'm gonna call Cavanaugh and let him know.
Go ahead, call Cavanaugh.
Let him know what? Uh we have another victim.
But this one's alive.
I was training for a marathon.
Uh, you know, bad breakups and whatever.
Um, it was pretty late.
I was working long hours back then.
I had just finished my run and, uh, I ducked in to get a bottle of water.
There was a there used to be a convenience store there on the corner.
But they've torn this whole block down.
So, you come out and you head Uh, back towards my house.
And then the next thing I know, there's a, uh there's a-a plastic bag over my head.
And, um, he's trying to get me down on the ground.
Take your time.
It it was the gloves.
When I read on Sophe that some of the victims had friction burns from the latex, that's when I knew it was the same guy.
Did you see his face? It was dark.
But I remember that he smelled like strawberries.
Not the real kind, the, um sickly sweet medicine kind, like the the artificial kind.
Um and then I fought him off.
(TAKES DEEP BREATH) I don't know how.
I kicked, I fought, I I just ran.
As tired as my legs were, I ran all the way home.
But, you know, I haven't run since.
Every day I just stare at those shoes, and I can't.
We're gonna get this guy, Ms.
Vincent.
I promise you that.
- Mr.
Tanner, I've already told you - Yes? That due to the HIPPA regulation, I know, you already Yes.
I cannot divulge information regarding any patient who may or may not have - been treated at this facility.
- Will you listen? - The door's right here, sir.
- We, uh, we - we both we both know - Not here, not now.
that Ryan Booth was a patient here at this facility.
Okay, I understand that you have these laws to protect people, and I get it and I respect that.
My daughter was was 22 years old, and she could have done whatever she wanted with her life.
And she chose to devote herself to helping others.
And she volunteered here.
That has to account for something.
Mr.
Tanner, I am sorry for your loss.
I truly am.
But I'm afraid there is nothing I can do, and you must go.
Have a good day, sir.
Mr.
Tanner.
I'm a huge fan.
I actually met my partner in a AllSourcer chat group "Quidditch Quorum.
" Are you still looking for Ryan Booth? Did you know him? Oh, no, he was way before my time.
But when I saw on Sophe you were looking for him, it reminded me of something.
I found it cleaning out the art room.
One of the other nurses said that Ryan Booth made it.
I guess he made one for everybody.
I was gonna write in, but I didn't want to get in trouble.
Did I help? More than you know.
Thank you.
Yeah.
(CAMERA SHUTTER CLICKS) (NO AUDIO) Zwart Schaap.
(NO AUDIO) MAN'S VOICE: Zwart Schaap.
CARLOS: No, he can't call me back.
I told you, because I'm in Never mind, just tell him that it's an emergency.
(QUIETLY): Tell him I might know who killed Mia Tanner.
What's up? You, uh, get everything you need, or No.
Not yet.
This is pointless.
17 murders and an attempted murder, and they're all over the place.
Physical evidence is different form victim to victim.
I mean, this one had latex burns but no fiber.
This one has fiber, no latex.
Cause of death for most of them is asphyxiation, except for these three, they were shot.
Some of the bodies are left at the scene, Some are traveled and dumped.
And what does the smell of strawberries have to do with any of it? He's out there.
The sick bastard that did all this is still out there.
If it was any other case, we'd be looking for geographic similarities.
Look at this map.
Here.
This is the corner where Miranda Vincent was attacked.
Not only is the convenience store not there, but this alley is supposed to be right next to it.
That's not there, either.
Yeah, I know.
The whole region has changed.
Some of these maps are too old, but some are too new.
How are we supposed to find similarities if we don't know what the area looked like when the murders went down? I have an idea.
Where are you going? We are going down the rabbit hole.
(INDISTINCT CHATTER) Lieutenant Ruiz.
Glad you finally figured out that we can help.
Believe me, this wasn't my idea.
Well, you just leave the ideas to us.
I think those together would be great.
Hey, so, um, it took a little doing, but between construction permits and city change orders, we managed to reconstruct what the neighborhoods would have been like at the exact date - of each of the attacks.
- You can do that? I've always wondered, do police phones have buttons now or is it still that old rotary-dial-type Ignore him.
As I was saying, we discovered an interesting trend.
Yes.
Each of these neighborhoods was undergoing rapid redevelopment at the time these murders occurred.
Can you see that? CAVANAUGH: Construction.
TANNER: Yeah.
- Mm-hmm.
- It's not that the neighborhoods changed.
It's the construction itself.
- Exactly.
- Precisely.
At the time of each of the murders, there was an active construction site within three blocks of where the body was found.
That might explain the trace minerals we found on some of the bodies.
We're looking for someone who worked - at every one of these sites.
- Mm-hmm.
Find him, and you'll find your killer.
Thank you.
So, Jeffrey, I'll get right to the point.
I think the board was crazy to let you walk out the door with Sophe.
We both know crowdsourcing is the next evolution in social networks.
I want AllSourcer in on the action.
And they said you weren't a visionary.
- (MIKE CHUCKLES) - Look at that.
(CHUCKLES) - Right? - I think I think I think, actually, what Jeffrey means - Look, uh - is that he's looking I-I spent the better part of a year trying to get Sophe away from AllSourcer.
Why would I want to put her right back in? Well, I understand you're having some cash flow issues.
Word gets around.
You know, we're willing to make a substantial investment that will enable you to grow Sophe organically.
And all I ask in return is access to Sophe's underlying I.
P.
The I.
P.
that I specifically carved out before I left? (CHUCKLES) Why No, I'm sorry, why would I want to do that? Or I could just wait for you to fail and then pick up - the pieces.
- Ah, see, I thought this was gonna be a hostile takeover.
I was completely wrong.
It's a passive-aggressive one.
MIKE: Look, maybe there's a way that we can arrange a mutually beneficial partnership.
Look, the-the problem with any partnership is there are strings attached.
The only way, moving forward, to make AllSourcer whole is to monetize Sophe.
So making money is a problem now? What Sophe is about is people wanting to be a part of something bigger than themselves.
Yes, I understand that, Jeffrey, - but I don't think you understand - (PHONE CHIMES) what I'm offering here.
I have to take this.
- I got to go.
- The You're gonna go? Jeffrey, where What do you think Jeffrey.
So, we combed through the official records, but we couldn't find any one worker who was ever at more than a few of the locations.
But you've got subcontractors and off-the-book workers.
Exactly.
That's where our users come in.
Yeah, we've got photographs and all kinds of documentation coming in on all 17 construction sites.
Uh, what's with all the flashing? User input.
People are highlighting regions for analysis.
SARA: They're trying to find common elements in the photos.
So, one user selects an item, and then the others weigh in on whether it seems relevant or not.
Wouldn't a computer be faster? Mm.
Visual comprehension is actually one of those things that's better done by humans than by microchips.
It's not elegant, but intuition plays a big part.
- (BEEPS) - And we have a match.
"Ever-Fresh Sanitation Services.
" How's portable outhouses for a link? (GASPS) That strawberry smell.
- Deodorizer.
- Yeah.
TARIQ: A company like this, they probably have a dozen open construction sites right now.
CAVANAUGH: Then we better hurry.
Send the address to my phone.
We'll get it on the way.
Damn it, Jeffrey, that was her asking nice, okay? The next offer is going to come across some lawyer's table.
So just Just call me back.
Where the hell is he? He's not with you? No.
He pulled a Houdini on lunch.
He got some text, then just took off.
Oh, that might have been me.
Yeah, some user in Cleveland tracked down that wire sculpture Tanner posted on Sophe.
Said he bought one online a couple months ago.
Return address was up in Guerneville somewhere.
Guerneville? (ENGINE REVS) RYAN: I didn't kill your daughter.
I knew you were looking for me.
I'm not a total hermit.
But I'm not the guy.
Not the guy that killed my daughter? Put the axe down.
Put it down.
I'm not the guy.
The night Mia died, I was on day three of a two-week intensive care stay.
I got a stack of bills inside I could show you.
They're still trying to collect on them.
Then why? Why what? Why were you grabbing her arm in the photo? Why don't you have a seat? Here you go.
I was crazy about her.
Completely unrequited, might I add.
Hell, anyone who met her was.
There was a party the night of the protest.
I knew she'd be there, so I showed up.
I was messed up by the time I found her.
Drunk, high, whatever else you can think of.
(LAUGHS SOFTLY) Uh, she read me the Riot Act.
Wanted me to call my sponsor, you know, go to a meeting.
Even as mad as she was, she always wanted to do the right thing.
I grabbed her.
I'm not proud of that.
I was just trying to convince her to come home with me.
She didn't.
(CHUCKLES) You'd be proud.
Man.
It's a hell of a thing, pissing off the nicest person you ever knew.
She wouldn't even let me visit her at work.
She said that, uh, she thought it might be distracting if everyone knew that she was Jeffrey Tanner's daughter.
(CHUCKLES) Yeah.
Did you see much of her, at Grand Pines? What she was like with the doctors and the patients? 'Cause I know that interning is like 90% coffee and paperwork, but she must have left an impression.
Oh.
Um Mr.
Tanner.
Mia wasn't an intern at Grand Pines.
She was a patient.
She was She was a what? Checked in the same day as me.
She said, you know, he was depressed and needed to get her head straight.
Well if he has any more dead bodies, we sure won't smell them.
(CREAKING) Well, hello.
Don't get many walk-ins around here.
Byron O'Malley? You can call me B.
J.
, sweetheart.
You, uh, want to rent some units? San Francisco Police.
Oh.
- Keep your hands where I can see them.
- Oh, no, I I'm not much of a threat.
Come on in.
(GRUNTS) Come on.
You're, uh Y'all acting kind of jumpy, aren't you? Business records indicate that you're the sole proprietor.
Is that correct? - Sure.
- One of your workers might know something about a criminal matter.
Well, you're gonna have to be more specific.
Um, I've got guys coming and going all the time.
CAVANAUGH: Uh, someone who's worked here for 12 years or more.
Uh, there's only one guy been there that long.
Don Farrel.
What's Donnie done now? Well, you tell us where we can find him, and we'll see.
Well, you're not gonna have to go far.
He's right here.
RUIZ (WHISPERS): Tommy.
Where's he going? CAVANAUGH: Police! Give yourself up, Farrel! (CLATTERING) Police! Stop! RUIZ (OVER RADIO): There's a room in the back.
I got him.
(THUDDING) San Francisco Police.
Show me your hands.
Show me your hands now! I'd do what he says.
Interlace your fingers behind your head.
Hurry up.
What took you so long? (HANDCUFFS CLICKING) SARA: He was trying to dispose of the shoes in a vat of acid.
Machine learning, baby.
How's that for the power of math? TARIQ: Uh, not so fast there, Archimedes.
My photo-matching software found those toilets.
I broke the case.
