( gunshots )
Robin Brooks, look at you.
What's going on?
I didn't think U.S. Attorneys were allowed to get their hands dirty.
Well, you can't prosecute what you don't understand, right?
Wow, look at that. That's a lot of gun, huh?
Yeah, well, it gives me a chance to actually hit something.
( chuckles ) Look, I didn't get a chance to thank you after the Jon Owens case.
Ah, that's all right.
No, your team handled it all really low-key, and because of that I was able to go forward with my gang case.
Good. I'm glad it worked out.
So, do you always hang out at the gun range alone on a Friday night?
Well, clearly it's where all the pretty girls show up.
Agent Eppes, I don't think I've been hit on at a gun range before.
( cell phone rings )
I'm on my way. Right.
What's wrong? I got to go.
Are you okay?
Yeah. I got to get out of here.
( Engine starts ) Okay.
I'll talk to you later.
( police radio transmissions )
ATF Agent Nikki Davis.
Killed herself two hours ago.
Gunshot to the head.
Who made the 911 call?
LAPD uniform involved in an unrelated foot pursuit heard what appeared to be a gunshot.
( police radio transmissions )
( camera clicks )
Agent Turner. Bureau of Alcohol, Tobacco, Firearms.
Look, I know any death involving a federal officer is technically the FBI's, but she was one of ours.
So, I'd like the handle on this.
Look, just... I want her covered as soon as possible.
You got it?
I said ATF wants the investigation.
Well, we're taking it.
I'll keep you in the loop.
CHARLIE: We all use math every day, to predict weather, to tell time, to handle money.
Math is more than formulas and equations.
It's using your mind to solve the biggest mysteries we know.
DON: Nikki may have been ATF, but I want her treated like one of our own.
Our responsibility is to clear the death of any federal officer, right?
You're not handing this over? No.
How we doing on ballistics?
Single round, matches her duty weapon, a Sig Sauer 229.
Oxycontin and Prozac.
Yeah. It's not that unusual for a suicide victim.
Any word on the husband?
He's an ATF agent.
Works fugitive gun runners.
On his way back from Texas as we speak.
I want him interviewed as soon as he lands, all right?
So, I'm just wondering if this woman's death was a suicide, why all the intensity?
She's the third agent in two years who killed themselves.
So it's strictly professional?
You knew her, didn't you?
Does say "behaviorist" on my job description.
Yes, I knew her.
Well, if you ever want to talk, I'm number two on your Nextel.
I'm going to head over to the ATF and interview her whole team now.
Hi, Charlie. Hey.
Take care of your brother in there.
CHARLIE: What'd she mean by that?
Looks like an ATF agent who I knew pretty well killed herself, that's all.
Oh. I'm really sorry.
Yeah. Do you remember that kid who jumped off the bridge last year?
Yeah. Finn Montgomery.
It looked like a suicide, but you didn't think so, right?
Right. I didn't think he was capable of it.
His potential was unlimited.
Good more than outweighed the bad.
But I was wrong.
Well, do me a favor, take a look at this file.
Just tell me if there's something doesn't add up, would you?
( writing on chalkboard )
Nothing like taking stock of one's life.
Bit safer from a numerical standpoint.
It isn't his life Charlie's taking stock of.
Okay, well, even easier still.
A hundred people commit suicide every hour.
And 300 stars die every second.
Yeah, this was a person.
Nikki Davis -- she was an ATF agent.
So, what, you're weighing events in her life to determine the likelihood of her suicide?
I'm applying a modified Holmes-Rahe stress test as a starting point.
We're assigning numerical values to certain events in her life.
Yeah, but how do you rank such things?
I mean, Christmas alone, dinner with your in-laws could equal a death in the family.
I mean, depending on your in-laws.
Oh, she was a par golfer, ran sub-three-hour marathon times, and even worked at the local Boys and Girls Club.
All positive things.
Yeah, and she was also on antidepressants.
What, they're handing out guns to the clinically depressed?
Depression is a definite negative.
But my cognitive emergence studies have taught me that it's difficult, but not entirely impossible, to quantify the variables that describe existing human consciousness.
And Don has asked you to work on this? Why?
He knew her.
Yeah, he knew her, a long time ago.
They hadn't spoken in years, but I think he's really bothered by this.
Yeah, well, like I said, leads me back to those stars.
One dies and disappears, and the whole cluster feels the loss.
( small explosion )
ATF! Search warrant!
Drop the gun!
( laughs )
AGENT: Took a little time there, didn't you?
Nice, guys. Hey.
TURNER: This is Agent Reeves and Sinclair.
They're clearing the inquiry on Nikki's death.
Sorry for your loss.
Fingernails so clean, he's got to be FBI.
TURNER: They're here to help, Agent Rho.
So are you.
WILSON: Nikki was our leader, we lost her.
What else do you need to know?
( chuckles )
We'd like to know whether she seemed depressed at all.
Was something bothering her more than usual?
Nikki always had a lot on her mind.
Goes with the territory.
We found some medications on her bureau -- pain killers, antidepressants.
Is that what this is about?
Some kind of FBI thing to try and drag her name through the mud?
We're just trying to investigate.
Yeah, well, I know all about these kinds of investigations.
And you can count me out.
TURNER: Agent Wilson.
Look, she's upset, all right? We all are.
MEGAN: We understand that.
We're just trying to sort some things out.
Nikki hurt herself pretty bad last year.
On the job?
Executing a warrant.
RHO: Messed up her knee real bad.
Never took the time to heal right.
No rest for the wicked, she used to say.
Agent Rho... if you think of something, just let us know.
You need anything else?
We'll be in touch.
Just give me a second.
You know, you'll get more power in your punch if you turn your foot into it.
A lot of people think we should still be sitting behind a desk.
Must have been nice having a female boss.
Did you know she was self-medicating?
We were working a pretty heavy bank robbery crew.
Maybe she was a little off, maybe the stress was getting to her.
I don't know.
Wouldn't you say taking your own life was more than being a little off?
I got a job to do here.
I have to ask somebody these questions.
She was having problems at home.
With her husband?
Two ATF agents maintaining a relationship isn't exactly the easiest thing to do in our business.
How serious were the problems?
Pretty serious, I think.
Something he did backed her into a corner.
I don't know what it was, but she said she was thinking of calling it quits with him.
They don't call it eating your gun for nothing, do they?
MEGAN: I don't know if you're going to want to hear this, but after talking to Nikki Davis's team, I do believe that she killed herself.
I'm not as convinced.
I've been looking through her file.
Agent Davis was a leader in her community, she was an outstanding agent.
Who was suffering from a bad depression.
True, but look.
CHARLIE: Commendation after commendation.
She just made supervisor.
Strong parental support and siblings.
All of this should have outweighed any transitory depression.
Here, look, figure skaters, when they perform a routine, the judges multiply the scores on the jumps by a difficulty factor.
If that difficulty factor's large enough, and even with the mistakes and the subsequent deductions, skaters can still win the competition.
All the positive aspects of Nikki Davis's life should have multiplied her natural coping ability.
And so I think we should look at this further.
Charlie, look, if I'm going to rule her death a homicide, I need more than skating metaphors, you know?
I need evidence. We might have it.
DAVID: Nikki's husband's flight from Texas arrived, only he wasn't on it.
What do you mean? I checked the manifest.
He never got on the plane.
Found out his wife's dead and he didn't come home?
Ran a trace on his cell.
What's five-two? Mexico?
DAVID: Night of her death he was in Mexico City, not in Texas like he was supposed to be.
Also, I ran a trace on her cell, all calls in the last 48 hours.
One number pops out; it's on page two.
Last person she called was you, Don.
DAVID: I rechecked everyone's voice mail.
She didn't leave a message.
I mean, I don't hear from her for years, and then she calls me a few hours before she kills herself?
Well, maybe the kind of message she was leaving, she didn't want to put on an answering machine.
And what's her husband doing in Mexico?
Credit cards show he made a bunch of trips down there, all to the same town, just south of the border.
MEGAN: He's working gun runners.
Maybe it's an undercover assignment.
No. Not according to Turner.
I mean, they thought he was working a case in Texas.
And if he is on the job, why is he putting it on his own dime?
I mean, especially with his financial situation.
What? What's that?
Credit report shows he took a second mortgage out on his house.
Yeah, about six months ago, he started borrowing against his pension.
I don't know, but whatever he's buying down there, no, he's not using the credit card for it.
MEGAN: Well, I'll say this for him.
The man gets results.
One bust alone last year netted two crates of M-16s.
Look, just keep digging, all right?
I mean, I want to know what the guy was doing in Mexico, okay?
( sighs )
I can't remember the last time I saw you just taking a break.
Oh, it's a beautiful day.
I needed to get outside.
Yeah. Larry says that you've been distracted.
It's the ATF Agent?
Well, my research has revealed that law enforcement officers are more likely to commit suicide than civilians.
Well, it's not really surprising, is it?
I mean, they're around violence every day.
They see things most of us don't even know exist.
They also have a terrible track record at maintaining relationships.
Yeah. My parents had a friend.
He was a detective, and, um, well, the last time I checked, he was on his third wife.
He was always getting called off in the middle of the night.
He missed her science fair, her school play.
I worry about Don.
Where his work takes him, how's he ever gonna have a relationship?
It's just, I mean, we both know that you're not exactly the most successful man in the world when it comes to maintaining a personal relationship.
And Don has made his work his life.
So have you.
What's even worse is, you've made his work your life.
Look who's talking.
Look, we all have professional commitments.
But that doesn't mean we're not responsible for the choices we make.
Nothing is written in stone, Charlie.
Don can find somebody.
I mean, he just has to be willing to.
Looking for evidence or a keepsake?
We've been looking all over for you.
My boss told me.
Said you were handling the investigation.
Yeah, well, that's right.
Looks like, uh... you and Nikki had a lot of fun in New Mexico.
Yeah, well, you know, it was a long time ago.
And you decided to handle her suicide, what, for old time's sake?
She called me a few hours before she died.
About what? I don't know, Richard.
Why's your boss thinks you were in Texas?
Well, I don't think that's really any of your concern.
Well, you're wrong about that. Hmm.
I mean, you're in debt up to your eyeballs.
What are you doing running around in Mexico?
What are you doing, Eppes?
I'm just doing my job here, man, that's all I'm doing.
No, you're not.
You're trying to clear your conscience.
You left Nikki.
Well, it took her a long time to get over that, you know?
It hurt her pretty bad.
Look, let-let's just talk about Mexico.
They sell drugs there.
Uh-huh. So, what, you got a problem?
The drugs weren't for me.
I saw her tox screen.
The only thing in her system were prescription drugs, so...
Well, they were experimental.
What does that mean?
Nikki had cancer.
( Inhales deeply )
She was diagnosed about a year ago.
( sighs )
Hey, look, you know, um, I didn't know.
I mean, it's, it's not in her file, so...
That's because we didn't tell anybody.
ATF -- they, um...
They would have put her on leave for sure, and Nikki... wanted to keep working.
If you don't believe me, wait for the autopsy.
All right, just no more trips to Mexico, okay?
Until this is over, all right? No more trips?
No more trips?!
How about just, um...
How about just a simple "I'm sorry for your loss, and I think I'll be on my way"?
DAVID: Like this whole thing isn't weird enough, he runs into the husband in her bedroom.
What was he doing at a crime scene alone?
Here's the other info from the scene.
MEGAN: Thank you. Hey, Charlie.
Hey. I thought I'd stop by, check up on my brother.
Well, he'll be back in a few minutes.
Is this the radio communication from that night?
DAVID: Yeah. Radio communication?
Yeah. Some uniforms were chasing a dealer.
They called in for backup and think they heard a gunshot.
Are you saying that this is a recording of the gunshot that killed Nikki Davis?
Maybe. It's pretty distorted.
There's a whole lot of other noises on there.
How does this help?
Well, if it is the actual gunshot, it'll tell us the exact time of death.
Well, then, I can create an acoustic fingerprint for this shooting.
From the CD? Yeah.
Yeah, we... Look, we know where the shot was fired, right?
And assuming that the sound was picked up by more than one radio, and that I can have access to that same firearm, well, then, well, then, yeah.
I can... I can recreate the same variables.
I'll make you a copy.
ALAN: Well, she's cute.
Where was this taken?
Why is it whenever I see an old photo of myself, I look totally different, and you look absolutely the same?
I mean, we-we have the same genes, don't we?
I don't understand it.
Yeah, well, she's dead.
Apparently a suicide.
You know, she called me a few hours before.
Why would she call you?
( sighs )
I don't know.
Is there anything I can do?
( quietly ) She had cancer.
I see. You know, I just...
I have a hard time getting my head around the fact that she couldn't find some other way to...
Yeah, I know.
Yeah, I guess you would, right?
Did you and Mom ever talk about what would happen...?
I never wanted to.
I guess we were just lucky it never came to that, but...
I mean, if she had chosen to, I would have understood.
And I never would have blamed myself.
You understand what I just said?
I got to go, Dad.
See you later, Pop.
Yeah, all right.
( gunshot )
LARRY: No, it still doesn't match.
Are you sure we set up these outside microphones correctly?
Because nothing can be discounted here.
You know, an experiment like this, there's such an extremely high level of difficulty.
Why is that?
Because there was an open window, the sound envelope and how the waves reached the microphones -- they require truly complex calculations.
In an auditory sense, a gunshot is fairly unique, in that it produces a short, intense sound impulse.
And how exactly does this help me with a timeline?
Well, if we can recreate the original acoustic fingerprint, then we can match it to the sound recorded by three separate LAPD officers.
You know, forensic acoustic experts did this exact same thing in the JFK assassination inquiry to determine whether or not there really was a gunman on that grassy knoll.
Now, are we sure everything's exactly the same as it was?
LARRY: Hey, it just occurred to me.
That shade -- was it open or shut?
Does it matter?
Cloth doesn't reflect as much sound as glass.
Look, as we fire our test shots, this program will measure muzzle blast and echo pattern, so it is essential to get an acoustic match that nothing in this room be changed, added to or eliminated.
Tell, you what, let's... let's just try it again?
Yeah, go for it.
( gunshot, beep )
Not even close.
All right, now, just throwing it out there.
Maybe it wasn't a gunshot.
No, it was a gunshot.
LARRY: Listen, the recorded waveform was bouncing around much more.
Something is missing here.
Are you sure that there wasn't some evidence removed from this bedroom?
A shell casing maybe.
And the bed sheet, that's it.
No, that's just fabric to fabric.
According to my variations, we're looking for something much larger.
Okay, her body, but if I understand correctly, that's why I'm in the room firing from the bed, right?
Wait. David, where's Don?
At the office.
CHARLIE: Sound waves.
A gunshot produces a sound wave that travels, okay?
If the wave hits a reflective substance, let's say like rock, the air pressure energy of the wave moves back in the opposite direction towards you.
An echo? Exactly, but those returning sound waves don't just allow us to hear the gunshot.
They tell us what we can't see.
Like bats, for example.
A bat emits a sound wave and then listens carefully to the echo it produces.
Now, by hearing how long it takes for the echo to return, the bat's brain automatically knows how far away an animal is.
The larger the animal, the louder the echo.
If am animal is moving toward or away from the bat, the pitch of the echo will be raised or lowered accordingly.
It's the Doppler Effect.
All right. Yeah, so? And?
And we recreated the acoustics of Nikki Davis's room using the same communication system the officers used, and we found that there was something missing.
Missing? Actually, someone.
I think that there was someone else in that room when Nikki Davis died.
All right, wait, wait.
Are you sure about this?
The acoustic pattern clearly shows extra movement and mass.
Don, I'm telling you, there was someone else in the room.
DAVID: It can't be Nikki's husband; we know he was in Mexico.
Doesn't mean he couldn't have helped plan his wife's murder, though.
All right, here we go, I want to start over, all right?
We're going to comb his file, hers.
I want to find anyone with potential for this.
People with a grudge against Nikki is going to be a long list, Don. That's all right.
We've got informants, people she's put behind bars.
Just tell me, his file's on this table? Right here.
This his? Yeah.
Uh, wait a second.
Based on what I see here, I can help narrow that list down a little.
Why, what do you mean? What's this?
The forensics report.
We've already been through that, Charlie.
Right, well, DNA samples were taken from Nikki Davis's house.
A few dozen, actually.
It's a house, Charlie, anybody going in could have left a trace -- we have hair, fiber, skin, fingerprints.
That's exactly my point.
Charlie, we ran the samples, there was no matches.
Yeah, and without a suspect, it doesn't even help us.
You guys are talking biology, I'm talking probability.
Look, 99.99% of our DNA is the same.
But that doesn't mean we can't find markers that differentiate one individual from another.
Like genes associated with a particular trait.
That's exactly right.
For example, we can with high accuracy determine an individual's origin:
European, East African, Sub-Saharan African.
Fine. How does this help us?
CalSci has a DNA database.
50,000 DNA samples, and the photos of the people who donated them.
I can run a statistical matrix to find similarities between the samples found at Nikki's house and the samples at Cal Sci.
Wait a minute, are you saying you can tell us what these DNA samples would actually look like?
To a reasonable probability.
Well, go for it, run it.
MEGAN: All right.
So, the last six months, Nikki's primary focus is investigating a series of armed robberies.
Five months, five jobs, $1.5 million.
Guys move with tactical precision.
What was ATF doing on that case?
Agent Rho said the crew used military-quality weapons.
Maybe ATF's handling the trace.
Was she having any luck?
She had an informant who linked these guys to an Aryan motorcycle gang: the Outlaw Renegades.
It's run by a guy named Roy Mitchell.
Looks like she put surveillance on the gang based on information from the informant.
Anything come of it?
Her team spotted the Outlaw Renegades outside a bank, then ATF waited on these guys.
How come there were no arrests made?
They never went inside the bank.
Someone tipped these guys off.
Right, they knew they were being watched, that's why they didn't go inside.
Maybe the informant was playing both sides.
LARRY: Isolating a person from DNA linked to a government database?
I can't help but wonder, is this even ethical?
Oh, it's no different than fingerprints or driver licenses.
Listen, I see a very real distinction.
Driver licences provide a person's identity, but DNA, that contains the essence of our history, glimpses into our genetic future.
I'm merely using DNA information that's already been collected to approximate the genetic description of an ATF agent's killer.
Oh, I agree, in this case, you know, the intentions is pure, it's admirable, even.
But, you know, DNA can be used for much less noble pursuits.
I mean, predetermination, Charles.
Think about it, once we're trapped within these databases, our employers, our insurance companies, you know, they can use our genetic codes, and not to glimpse our futures, but to limit them.
( knock at door )
Nice to see you.
Robin, I need a favor.
Really? Oh, you could have just called.
Oh, right, but I forgot, apparently you don't know how to do that.
No, no, no, listen to me, it was a friend of mine, okay?
An agent, an ATF agent was killed and, uh...
I mean, that's the only reason I took off.
Wow, I feel really silly.
No, don't, please.
How can I help?
Well, she was working with an informant who was giving her intel about the Outlaw Renegades.
Yeah, I know them, our office has wiretaps on them.
Well, I figure the warrants are based on those tips.
I need to know who it is.
Those wiretap applications are sealed by court order.
Look, the ATF isn't going to help me because I took the investigation away from them, so...
Well, it's not my case.
But I'll talk to the AUSA that's handling it, and... see what I can find out.
All right. I appreciate that.
This woman was close to you?
You know what? I'm sorry, that is none of my business.
It's all right.
You know, I'll tell you about it.
All right. Well, you know where I work, right?
He's an Outlaw Renegade, right? Yeah.
Nikki arrested him last year?
Yeah, she flipped him, he's been giving intel to the U.S. Attorney's Office.
He lives alone, doesn't he?
Two cars in the driveway.
( knocking )
FBI! Looking for Darryl Clark!
MEGAN: I'll take the back.
What do you got?
He's been dead for a while.
MEGAN: Guys? Out back.
It's Nikki Davis's husband.
Two shots, center mass.
He wasn't just killed, he was executed.
All right, so we know Nikki's source was giving her intel on the Renegades, right?
DAVID: Right, they must have found out he was a rat and they took him out.
Yeah, but what about the husband?
Why kill him?
Yeah, and what's he even doing there?
DAVID: He's probably following the same trail we were.
He wanted to know if the informant was playing both sides, if he betrayed her.
What, he went to avenge the wife's death, right?
You know, Annie Wilson, the girl on Nikki's team, told me their marriage was in trouble.
She said something, uh...
"Something the husband did backed her into a corner."
You think he could have been involved?
Well, the guns the robbery crew uses are military grade.
And Davis definitely had access to those.
Now, he recovered those assault rifles in that bust last year.
MEGAN: Right, and they're in financial trouble from the wife's illness.
Maybe he thought selling the guns would help her.
Nikki finds out, she has no one else to turn to... then she calls you.
MEGAN: And gets killed before she has a chance to do it again.
All right, so I want 24/7 surveillance on everyone in this photo.
And this guy, Mitchell, pops out of his hole, I want to know it.
Hello? Oh, hey.
Am I interrupting something?
Just another Fleinhardt doomsday prophecy.
Come on, you make me sound like Chicken Little.
I was merely advising Charles as to the dangers of unleashing a genie from a bottle.
He's thrilled with the idea of cataloging DNA.
Well, why, Larry, do you have something to hide?
No, my DNA is pure as the driven snow.
Then what's the problem?
The problem is, once something is out of the bottle, it is out of the bottle for all time.
What? The bottle.
That's a useful metaphor.
Right. Listen up.
I've identified several groups of genetic markers called haplotypes, and now I need a set of algorithms to compare them against the Bio department's photo base.
And these algorithms can help you identify the people who left traces of DNA in this agent's house?
Like a blueprint for a home.
The DNA that builds a person are like bluprints that build tract houses.
A majority of the characteristics of each home -- roof, dimensions and style -- is exactly the same, but there are a small number of things, like color, landscaping and, say, window coverings, that makes each home -- like a person -- unique.
With a little luck, I may be able to put a statistical face on all of Don's samples.
It's like some "bizarro" DNA world.
DON: When I was at Quantico, I remember all this talk about pride and integrity...
I remember holding John Dillinger's gun.
Yeah, but they never seemed to tell you about cases like this.
I mean, here's my friend and...
I mean, she's murdered, you know, she's miserable... she's in yet another bad relationship.
Come on, Donnie, you're projecting now, aren't you?
No, I don't think so.
I mean, I don't know anyone in my game who's got a really good relationship.
Donnie, that can't be true.
Well, it is. I mean, I tell you stuff, but you don't know the half of it, trust me.
How come I don't find that comforting? It's hard.
You come home and someone says, "How was your day?"
And you're like, "Well, I saw a decapitated kid, how was yours?"
Well, I mean, if you can't talk about it, how are you going to feel any better than you do now?
Which is why there is nobody at home waiting for you.
Look, even when I could have had good relationships, I screwed them up.
What does that mean, damned if you do, and damned if you don't?
What if you didn't sabotage your next relationship?
Yeah? What does that mean?
I mean, what if you gave the next woman that you meet a real shot?
Look, Dad, it's easier said than done...
Donnie, what's the worst that can happen?
I'll tell you.
The relationship fails, right?
( cell phone rings ) So then what?
Then you're back where you are right now.
But the only difference is, instead of being afraid, you took a chance.
( cell phone continues ringing )
LAPD undercover just bought some dope about an hour ago.
ID'd Roy Mitchell, leader of the Outlaw Renegades, inside on the couch.
How many inside? Two plus Mitchell.
We'll come through the backyard, take them by surprise.
What do you say, boys, let's do it.
( guns being cocked )
Drop your weapon!
Get your hands around your back! Thumbs up!
( glass shattering )
We got a runner!
FBI! Don't move!
( electrical zapping )
You got nothing on me.
Well, how about two dead federal agents?
Which qualifies you for special circumstances and a lethal injection.
Yeah, you have any evidence?
What, you mean like Nikki Davis' husband supplying you guys with guns?
Is that what we're talking about?
Who's Nikki Davis?
She was the ATF agent working Darryl Clark.
You know who that is, right?
DON: Yeah, he was cooperating with the ATF.
Did you know that?
Ah, can't trust anybody nowadays, can you?
You killed him.
Just like you killed Richard Davis when he showed up.
Sorry. Not ringing any bells.
DON: Look, you got one chance, you hear me?
One chance to save your life.
MITCHELL: All right, look, you guys got pictures of me killing somebody, feel free to let me know.
Other than that, we got nothing to talk about.
ROBIN: Don, he's right.
What we have isn't enough to flip him.
Well, he's involved, all right?
There's no doubt in my mind he's involved.
I can't hold him.
Well, you can't cut him loose.
We don't have probable cause.
Nothing ties him to either crime scene.
Look, I'll lose his paperwork, all right?
I cannot let the guy go, Robin!
Look, Don, I don't know what this woman meant to you, but I doubt that she would want you to compromise yourself.
Neither do I.
We'll put him under surveillance.
Eventually, he's gonna make a mistake.
That's not good enough, Megan.
I'm sorry, it's not.
CHARLIE: Don! I got your guys.
Or your guy.
Or whatever. I got 'em.
Your DNA samples.
I was looking for major continental groups and searching for matches.
It's actually something that Larry said.
That I shouldn't be looking at specific physical characteristics, I should be adjusting my algorithm to identify origins.
So, I went back to the CalSci's DNA database and I found samples that most closely resembled the biogeographical ancestry of the eight samples that were pulled from Nikki Davis's house.
And I approximated the genetic probability of the samples' likeness.
Okay, how do we know which one's the killer, Charlie?
We don't -- well, not for certain.
But we can apply probabilities.
CHARLIE: I mean, look, we know that there were no fingerprints on that gun, so we can assume that the killer wore gloves.
So we can eliminate all secretion-based DNA samples from hands.
DON: What, we get these three?
Wait a minute. What is it, David?
One of these representations.
Does this remind you of someone?
Agent Rho from Nikki's team?
Yeah, that's pretty close.
But why would someone on Nikki's team want her dead?
Bank robbery detail described them as moving with military precision, right?
Yeah, and Rho was a former Navy Seal.
DAVID: Mitchell wasn't leading this crew, it was Rho's.
Call Special Ops; I want Rho under tight surveillance ASAP.
ATF has Rho out on a training scenario.
The location's undisclosed.
They're pulling a job, I know it.
They're pulling a job.
( tires squealing )
Get 'em up, now!
Fire in the hole!
No, don't shoot!
( sirens wailing )
Damn it, Feds are on to us!
Give me suppression fire!
( automatic gunfire )
Protect our flank!
DON: Cover me! Watch for crossfire!
( helicopter flying overhead )
( helicopter whirring )
( groans )
Don't do it!
Don't even think about it!
Get that hand up! Get it up!
Oh, thank you.
Okay, pizza's here.
Peppers and onions?
Uh, no, sausage.
Don's not coming over?
I called; immediately goes to voicemail.
Three agents cracked, Dad --
Nikki Davis, her husband and Agent Rho.
I mean, even his crimes can be traced to the pressure he was under.
What do you think, Don's going to crack?
He lives alone, and there are times we don't see him for days.
Who knows what he's doing?
Charlie, there's one thing I know about your brother: he always knows how to have a good time.
( sighs )
You're not seriously worried, are you?
That formula I was working on, I ran it against his life.
( laughs )
You know, you're worse than me.
You realize that?
He's going to be okay.
Yeah, well, I knew that a long time ago.
Most compelling reason: strong ties to his family.
And apparently, they to him, right?
Still, you ever wonder where he disappears to?
He doesn't disappear. He's, uh...
Turns his cell phone off.
Oh, all right, so he disappears.
He's going to be fine.
He's going to be fine.
( knocking at door )
This is a surprise.
