( panting )
It's okay...

( voice breaking )
Dad, it's me.

Pick up.

Stuff's happening at school.

I need you.
Come and get me.

Please!
Oh, my God.

BOY:
Hey...

DMG rules.

DISPATCHER: Where are you now?
In the cafeteria?

( voices yelling on phone )

DISPATCHER: Stay where you are.
Help is on the way.

MAN: I've been the principal
at this school for nine years.

We've had problems,
but nothing like this.

Okay, why don't you tell me
what you know so far?

Oh, God, there
were two shooters.

Eight people were killed.

Seven students and
one of my teachers.

12 more kids were wounded.

It all happened
in like six minutes.

All right, I'm going to want
to talk to the students,

teachers, security, everybody.

I'll get a list.

DAVID: Don,
found one of the shooters.

- Hey.
- Hey.

This is Paul Elins.
He's 17 years old.

He's a senior here
and he was absent today.

The headset, the mask, the whole
thing matches the witness accounts.

Looks like he killed
this girl right here.

Victim's name is Becky Flynn.

He shoots her and then gets
taken out himself. Thanks.

That has to be
the other shooter.

Security never got off a round.

So what do we think,
a suicide pact?

Yeah, only the other shooter
couldn't close the deal.

MEGAN:
Or didn't.

If we're talking about
a sociopath,

he might have told his partner one
thing and had something else in mind.

He probably escaped
in the crowd.

SWAT found his bag
and all his stuff

ditched in an empty locker
near the exit.

( phone ringing )

Is that hers?

Says "Dad."

It's gonna go to voicemail.

Hello.

Excuse me, sir.
My name is Don Eppes.

I'm with the FBI.

Um, look, sir, I'm afraid
I have some bad news.

We all use math every day,

to predict weather,

to tell time,

to handle money.

Math is more than formulas
and equations.

It's logic.

It's rationality.

It's using your mind to solve
the biggest mysteries we know.

Paul Elins was an honor student.

He excelled in math, computers

and he got acceptance letters from
half the schools in the Ivy League.

All right, so
where's the dark cloud?

Parents divorced last year.

He fell into a depression.

Discipline problems...

I mean, why he picked up a
gun and started killing other kids?

There's got to be
some kind of trigger.

All right, so who
were his friends?

I mean, the odds are the second
shooters a student now, right?

Who was probably absent
today, too.

Yeah, but even if we
isolate his friends,

we could still be
looking at a lot of kids.

DAVID: Well, this might help.
Student ID.

Theres a chip on the back.

School takes attendance
using RFID technology --

radio frequency identification.

That's a tagging system that
companies use to track packages,

inventory
and shipping and stuff.

I read the Technology section.

Yeah, yeah. And?

Chip on the ID communicates with a
network of sensors around the school.

Central computer
tracks the students.

It's like a GPS system.

That sounds a bit
Big Brother to me.

It's not 100%.

The kids leave it at home,
they forget it in the locker.

Well, it should definitely
be able to narrow it down for us

which kids were running away.

Which will tell us who we can
eliminate as suspects.

And anyone who was absent,
we can run down their alibis.

That school has metal detectors.

How did they get
the guns inside?

They got them in there somehow.

Well, if the system can
tell us where each kid is,

then we should match it
with witness statements

and map the shooters' route.

By "we," I mean Charlie.

I got you thinking
like a mathematician.

However, I'm not too keen
on your method.

See, there's a natural flaw
in witness statements.

And statistics show that
memory is often unreliable.

Charlie, that's all we got,
so...

Actually, you do have
more than that.

Neptune.

Neptune? As in the planet?

The discovery of Neptune occurred
because scientists inferred its presence

due to its gravitational force
on other planetary bodies.

From the observable,
we can divine the unobservable.

Right.

CHARLIE: Remember that
trick we did when we were kids?

The soap and pepper trick.

Yeah, you put pepper
in the water,

you put the soap in and then
the pepper goes everywhere.

Same principle.
Except let's say the students

are the specks of pepper

and the bar of soap
are the shooters.

The shooters arrive --
and just like the pepper,

repelled, in this case,
by breaking surface tension,

the students flee.

They scatter in
a predictable pattern.

Yeah, how's that?

AMITA: Using non-linear
pursuit-evasion equations.

Which show how predators
pursue their prey.

Yeah, but wait, you can
see the soap.

Here's the beauty of it.

Let's try this trick again,

but this time
with clear liquid soap.

Now you can't see the soap,

but the pepper behaves in
precisely the same manner.

It's just the same
with our two students.

Though they may be unobservable,

it's the observable --
the fleeing students,

that will tell us, not just how
the shooters got into the school,

but every single move
they made thereafter.

According to students
who were there

these shooters were
targeting people out in the open.

Jocks, popular kids, mainly.

A couple of them said these guys
would point a gun at one of them

and shoot the person
right next to them.

No one has exactly jumped
to the front of the line

to say they were best pals
with the shooter either.

Isolation also fits the profile.

Several students said
this kid Paul Elins --

he was a part
of a group of boys.

Called themselves the DMG:
"Dark Matter Guild."

Computer geeks mostly.

Do we know anything
else about them?

Well, apparently the editor
of the school newspaper

did a profile on them
a couple months back.

Her name's Karen Camden.
So, we're running that down.

Why is that name so familiar?

She was the other girl in the
closet when Becky Flynn was shot.

Whoever said that I'm the leader
of DMG, they're full of it.

Actually, you said it, Greg,

in an interview with
Karen Camden.

All right, you want to know
about the DMG?

It's simple.

We're just a guild
of gamers, that's all.

A guild?

I take it you don't know much
about MMORPG's.

Like starting with
what the hell they are -- no.

Massive Multi-Player
Online Role-Playing Games.

A guild is a team
of players online.

Of which Paul Elins
was a member.

Look, I'm as shocked about what
Paul did as anybody else.

What is the Dark Matter Guild?

Like I said, we're a team.

Dark Matter is just
a component of the universe

that exists all around us
that remains unseen.

Well, you and your pals
just stick to video games

or do you engage in other
activities, as well?

I don't know anything
about the shooting,

if that's what you mean.

Why were you absent from school?

I had a cold.

You look pretty
healthy right now.

Look, I told you,
I don't know anything.

And I can't think of anybody
in the guild

that would condone what Paul did,
let alone be a part of it.

The DMG are gamers,

not killers.

Poor Becky.

I keep thinking
why didn't he shoot me?

That's not your fault, Karen.

And you're never going
to know why.

It could be anything.
It could be because

you wrote that article in the
school newspaper about the DMG.

I just wanted kids to understand
who they were.

So many kids
dissed them, you know.

Calling them dorks, cyber-geeks.

You know, jocks pick on geeks
every day.

Bullying happens.

It just doesn't
usually end like this.

I could see his eyes

through his mask.

He looked so angry.

And what about
the other shooter?

I never saw him.

But he shot Paul Elins.

Yeah.

After I just sat there
and waited.

I tried to help Becky, but...

When I didn't hear anything,
I just ran.

You got to know these kids
pretty well, didn't you?

I guess.

Karen,

I need to find that other boy

before he hurts someone
else or he hurts himself.

Do you have any idea who
that second shooter might be?

There's a half a dozen boys
in the DMG.

It could be any one of them.

Yeah, but did you get a feeling
about any of them?

Did you have a thought that
maybe one of them

was capable of
something like this?

Anything you say to me
is just between us.

Paul used to hang with
this kid named Justin Price.

And what makes you think him?

Justin's scary...

into guns.

Always bragging about how
he has this huge collection.

And he always used
to talk about Columbine.

Thanks.

- Hey, guys.
- COLBY: Hey, Don.

Kid on the left is Justin Price.

Karen Camden describes him as
some kind of angry loner type.

Mom's a single parent.
She travels a lot.

Neighbor said she's away
at a convention right now,

so we checked the house.
There's no sign of him.

Yeah, I got a file on him.
He's got a juvie record.

Out of the 77 kids who didn't show
up on the attendance data that day,

we were able to account for 46
of them who were actually there,

just not wearing
their ID badges.

So what's that?
Like 31 absent, huh?

Yeah. Including
Justin Price.

So the ATF trace on the
guns at the school show

that they were registered
to a John Price, deceased.

He's Justin Price's uncle.
The guns were off the grid,

but, apparently, he
voluntarily registered them.

All right, I'd say we got our
second shooter there, right?

Hey, guys, what's up?

Our preliminary analysis of
the first minutes of the attack

show that the shooters entered
through the southwest entrance.

According to the police report,

the southwest metal detectors
were down

for scheduled maintenance.

Coincidence?

Well, as a prominent
cosmologist once said,

"Coincidence is the last refuge
of the uninspired."

What cosmologist said that?

Oh...

Hey, are these the two shooters?

Yeah. Kid on the right is the
other one we think might be. Why?

I know this place.

This is an all-night cyber cafe.

Yeah, they've got a
retro-version of Asteroids there.

I quite enjoy it.

Karen Camden said the DMG kids
were teased for being "cyber geeks."

If they're hiding out, they'd
probably go someplace comforting.

- And open 24 hours.
- All right.

Why don't you guys check it out?

( loud punk rock playing )

He's inside.
In the back room.

Alone?

Yeah. Isolated in the corner.

You two cover the front.
SWAT's got the back.

Let's do it.

♪♪

We're FBI.

We're gonna need
you to leave the room.

♪ ...committing double
homicide... ♪

Justin Price, FBI!

Everybody down! On the ground!

♪ One shot down ♪

♪ Two shot down... ♪

Call an ambulance.

No.

He was just a kid.

♪ Now they are laying
in the dirt... ♪

So the forensics came back
on Justin Price,

and the blood on his boots does
match the victims at the crime scene.

We got a second shooter.

Yeah, but there's
another problem.

The gun that David and Colby
found on Price at the cyber cafe

only matches two
of the five kills

that he's credited with
at the high school.

Yeah. Wait,
he didn't have any others on him?

No. And, like the first shooter,

he was probably packing
more than one gun,

which means that gun
is still out there.

Yeah. Plus the rest
of the uncle's arsenal.

Right. So now we have
a bunch of guns

and a bunch of
really emotional kids

who might have the potential
of getting their hands on them.

All right, so let's get
every single kid

in that DMG on
surveillance, right?

I mean, we got
to find those guns.

At 11:02:58, Scott Kang
was at X-Y coordinates 335/

211,

heading north.

Oh, evolution
is a cruel mistress.

Human intellect grows unbounded,

while our emotional
maturity is sadly behind.

Larry?

High school will always be
high school, you know?

The jocks versus the geeks,

and the popular versus
the ostracized.

I remember.

Yeah, but, you know, time was when
we solved our differences with fists,

not automatic weaponry.

Times change.

And it's not just guns.

RFID chips and tracking systems.

If this weren't the new millennium,
I'd swear it's all very 1984.

Mmm. You know, Megan
feels the same way.

Speaking of,

what was that smile
she gave you all about?

Oh, it's her smile.
Ask her.

Wait a second.

Can someone clue me in here?

Well, the fact is,
for some time now,

though it's not my
specific discipline,

I have felt a certain chemistry
with Megan.

Which you've kept
fairly well under wraps.

Precisely why my next overture
will be overt.

You're going
to ask Megan out, Larry?

Yeah. But I don't know.

Given our disjointed universes,

I'm... I'm fearful.

What is it, Charlie?

This last grouping
of data entries...

It shows students running
towards the shooter,

and not away from him.

But that obviously
doesn't make sense at all.

It could be an anomaly
in the data.

Or an anomaly in the school.

These school plans are old.

Walls could have been moved,
obstructions introduced...

If you're suggesting what
I think you're suggesting --

field work -- God, I vowed never
to return to high school.

Mrs. Price, your son
Justin was associated

with a group of boys at school

known as the
"Dark Matter Guild."

What can you tell me about them?

Just that they were friends
who would hang out,

play video games.

And have you ever
met any of them?

I met Paul Elins a few times.

I never met any
of the other kids.

I work in health care.
It's long hours.

I'm on the road
three days a week.

I wasn't able
to keep tabs on Justin

the way I would have liked to.

That sounds like
you were concerned.

I asked my brother John
to spend some time with him.

You know, I wanted him
to have a male role model.

He was in the service.

I thought he could teach him.

But, after John was killed,

it affected Justin.

Nothing that I said mattered.

And, Mrs. Price,
do you know where

your brother John kept
his collection of guns?

I asked him to get rid of them.

I assumed he had.

We think there's
more guns out there.

I ran a credit check,

and found a storage unit
that was leased in your name.

The fees were paid
by money order.

I didn't know anything about it.

You think I'm an awful mother,
don't you?

I think you're a woman
who's lost her son

and feels responsible.

My son murdered a teacher.

He killed all those children.

How do I live with that?

The banality of evil is only
banal to those who never see it.

My senior year, a student showed
up at school with a gun.

He held two kids hostage.

What happened?

Eventually, he let them go.

Then he climbed up
to the roof and jumped.

It's a different world
than the one I grew up in.

Any structural discrepancies
we had hoped to find,

we're not finding them.

Now, given the rate
at which my calculations

show that the shooters moved...

Hey, you guys, you know what?
I'll tell you what.

You guys mind if I borrow
your walkie-talkies?

Thank you.

Thanks.

What... what are you
thinking here, Charles?

You suggested I test
my equations in the field.

Time me.

Okay, Larry. Time?

Uh... 58 seconds.

Charles, what is it?

I need to talk to Don.

We searched that storage
locker that Justin Price rented.

Found some unused ammo.

But if he was storing guns there once,
they're not there now.

We did find this.
Take a look.

It's a security schedule.

Yeah. It shows that the
metal detectors were down

at the southwest entrance of the
school the morning of the shooting.

All right, so they knew
exactly where to enter.

Yeah. We found downloaded
blueprints of the school, too.

Hey.

What's this?

It's a home-made
"modded" video game

we took off of
Justin Price's laptop.

He was playing with Paul Elins
the night before the shooting.

What do you think? Like
some kind of dress rehearsal?

Only they weren't
the only ones playing.

We have evidence other
DMG kids were online as well.

Hey, guys, there's a problem

with the RFID data
I need to show you guys.

All right.
Well, put it up.

Okay, I managed to map the
movements of the students.

Now, these red dots --

these are students.

And the black X's --
those are the shooters.

Now, during the first two
minutes of the attack,

the students behaved
as one would expect.

All right. Well, then,
what's the problem?

Eventually, a group of students

actually started moving
toward shooter number two.

Maybe there was a dead
end over there or something.

No. No. I walked those halls.

There was no dead end, David.

Check this out.

These are the locations and the
times of death of our murdered victims.

Now, according to the data,

the time between the murder
of victim number four

and the murder
of victim number seven

was 33 seconds.

However, I retraced

the steps of shooter number two,

and I found that where

victim number four was murdered

to where victims numbers five,
six and seven were murdered,

took twice that amount of time.

So what does that mean?

We know that shooter number one
took out these three victims.

And we know shooter number two
took out these two.

What about the
other three victims?

There's only one explanation
for the aberration in the anomaly,

and that is that you guys aren't
just looking for a missing gun.

Guess what? You're looking
for a third shooter.

( hammer cocking, gun firing )

Agent Reeves,

my secretary says that you think
there was a third shooter.

I'm afraid that's
what it looks like.

First these shootings,

then Justin Price gunned down.

Now you say another one
of my kids is involved?

Where does this end?

I think as soon as we
find this third gunman.

I wanted to reopen school,

get the kids back
to some kind of normal routine.

I can see now
that's not possible.

Mr. Northrup, right now
we need your cooperation.

We need the files of everyone
associated with the DMG.

That might be a problem.

What do you mean? Why?

Well, the parents
of these children

feel their kids are being
unfairly singled out.

They've hired lawyers and they
make it clear that they won't consent.

So you're saying we need
a court order?

I'm afraid that's what
it's going to take.

There may be another way.

How?

Construct the information
from public records.

Military personnel have the same
access as colleges.

Transcripts, activities,
club memberships.

Justin Price
had a criminal record.

Maybe one of the members
of the DMG does, too.

Anything in the public record we
can use the Patriot Act to get at.

Eight dead, 12 wounded.

I'd call that an act
of domestic terrorism.

MEGAN:
More files.

Sorry, team.

Oh, it's okay.

Charlie promised to take a look
at the data

for my solar physics
presentation.

Thank you. And you still think
you can do this in one day?

Yeah, using my Support Vector
Classifier, yeah. Sure.

See, the algorithm's going
to go through it all, okay?

Grades, activities,
disciplinary actions --

to evaluate traits ascribed to
the FBI's School Shooter Profile.

Still seems like
a really tall order.

You know,
Michelangelo always said

that his
sculptures already existed.

It was merely up to him to
release them from their prison.

Well, what he means
is that this process

is a lot like that
of a sculptor.

Preserving only what's
relevant to the image he seeks,

a sculptor
chips away at a block.

Well, in this case,

the algorithm tells the
computer which details

from the public records to keep

and which to "chip away at" --

which to discard
as irrelevant --

until slowly an image appears

from this massive block
of data...

which, you know, if we're lucky,

correlates with an already
existing image:

the profile
of the random school shooter.

I know a lot of women who'd
like to get ahold of your algorithm

and run it against the personals
to find the perfect man.

Oh, hey,

you know you said we were supposed
to do something earlier, remember?

- What?
- You said it.

We're supposed
to do it. Let's go.

- Right.
- See ya.

Right. Bye.

What was that about?

Merely a very crude attempt
at lending privacy.

At the risk of sounding
embarrassingly misguided,

would you care
to join me for dinner?

Or a show, perhaps?

Or maybe even some
terpsichorean pleasure?

I don't know what
the third one means,

but dinner sounds nice.

- Okay.
- ( chuckles )

On one condition, though:

you have to take me
for a ride in the car.

Delighted.

- Call me.
- I will.

I will call you.

( chuckles )

Charlie said he's halfway
through his analysis.

So far, he's got no hits.

We're stuck without
those student files,

I can tell you that.

What about the court orders?

The kids' lawyers
are hemming and hawing,

so it may take the judge
another day.

I'm hoping this may help.

I found on the school's ISP
in the deleted files

an e-mail sent out
the day before the attack

cc'ing all the members
of the DMG

telling them to be careful
at school the next morning.

Guess who sent it?

What, Gregory Dietrich?

- Yeah.
- There you go.

I'm gonna give it to the judge
and I'm hoping if we push,

we might be able to
get a warrant for his file

in the next couple of hours.

All right. Do it.
Pick up the kid,

but let's be careful now,
all right?

Still revisiting
high school, Charles?

Just mapping our shooters'
third route.

You got a date, huh?

You don't seem too excited.

Mine is an inner frenzy.

Like some highly agitated
molecular brew.

I can't even settle
on a restaurant.

Well, you know,
Italian's always romantic.

The kinetics of angel
hair and red sauce,

it's a bit too much
of a challenge, I'm afraid.

Plus, I think I prefer
not to wear a bib.

I think you need to loosen up,
you know?

Free your molecules,
and your ass will follow.

Oh, yeah, well, sound advice.

AMITA: I just ran Gregory
Dietrich's student file through analysis.

He's the leader of the DMG.

He scored off the charts on
the FBI's School Shooter Profile.

Our algorithm
came through, my man.

Larry -- still debating
the complexities of capellini.

No, I'm just considering the
complexities of shooter three's route.

If your main goal was simply
to shoot other students,

why such a convoluted path?

I don't know. Insanity maybe?

Oh, no.

Even a crazy person can get
from point "A" to point "B."

MEGAN:
Two months ago,

Gregory Dietrich made an online
purchase of an "Evil Twin" kit.

What is that?

It's a hacking device
to tap into WiFi networks

and steal sensitive data.

So what?
So they can get blueprints

and security schedules,
stuff like that?

Exactly like that.

Our guys detected a WiFi breach
at the high school security database

a week after Dietrich
bought the device.

Traced it to him?

Yeah, the kid's not so smart,
after all.

Further proof of that.

Surveillance just saw him running
into his house like a man on a mission.

Ah,
the lawyer must have tipped him off.

He's making his move.

COLBY:
I can't get my head around

this whole high school
shooting thing, you know.

I mean, I came
from a small town.

There's 200 kids in my high school,
not 2,100.

Everybody knew everybody.

If some punk was running
around with a pile of guns

and bad intentions,
we'd know about it.

I don't get it either, man.

Where I grew up, this kind
of stuff didn't happen.

Don't get me wrong.

Kids got shot, but it was over
something, you know?

Pair of sneakers, insult, drugs.

It was definitely stupid,
but looking at those kids

shot in their own school...

Wouldn't have thought
about it at the time, but...

maybe we were luckier than we
thought growing up where we did.

Yeah.

There he is.

Five bucks says he runs.

Yeah? Ten bucks
says I catch him.

- I got the kid!
- I got the bag!

( siren blips )

( tires squeal )

You should spend a little
more time in P.E., kid.

Going hunting, Gregory?

I got nothing to say!

Yeah. That one's new.

Stand up. Let's go.

( gunshots )

WOMAN:
My client already told you

he had nothing to do with
the attack on the school.

Your client was in possession
of a semiautomatic weapon.

A gun that was part of a collection
of guns owned by Justin Price's uncle.

Which doesn't prove a thing,

unless that gun
was used in the attack.

Why'd you have it?

You don't have to answer that.

No, no, it's okay.

I want to answer him.

Justin gave me the gun.

We'd go off into the woods.

We'd fire off a couple rounds
at cans and stuff.

And while you were out there,

no one ever mentioned going
and shooting up the school?

That I won't let him answer.

You bought a device to hack into the
school's database to steal blueprints.

We have your name right here.

We traced it to you. It's your name,
isn't it?

Those blueprints
were for my game.

For authenticity.

For authenticity?

Wake up.

These are kids
you went to school with.

They were shot in cold blood.

Authenticity.

It wasn't me!

But you hated them, didn't you?

Look, why don't you guys
try living with it every day?

The way they look at you

like, like you're
not even there.

So you took your revenge.

It was Paul and Justin.

But you wish it was you,
don't you?

I think we're done here.

MEGAN:
His lawyer's right, you know?

The gun we found on him isn't
a match for our missing weapon.

COLBY: You're not going to
like this much, either.

His e-mail story holds up.

That warning that was sent out
to the other DMG members?

It was sent from his account,

but it originated
from the school library.

So he sent it from the school.

Not unless he was
in two places at once.

His school I.D. badge says
he cut out early that day.

His ATM card
and a security cam photo

says he was making a withdrawal
the same time the e-mail was sent.

He created the game,
he's the leader.

All this goes down and
he's got nothing to do with it?

I don't buy that.

( knocking )

Charlie, your advice --
"Free your molecules"?

I made a reservation for Megan
and I at an Ethiopian restaurant.

Ethiopian, on Fairfax.

Thinking outside the box.

Wish me well.

Hey, you know, um,
you were right.

Shooter number three's route
doesn't conform

to any predictable
pursuit-evasion result.

I'm thinking that I must
be missing a variable.

Up until now --
I got to be honest --

I think we've been looking at
this school shooting the wrong way.

Let's take a look at the route
taken by our first two shooters.

Their movement is methodical.

They are pursuing students in
a logical progression.

Now let's take a look
at our third shooter.

Appears here

and for the next minute
makes his way through the school

killing victims
until vanishing here.

Most likely changed clothes.

Shooter number three's route
is circuitous.

It's inefficient.

Yeah, but it's a random
shooting spree.

Doesn't it make sense
that he'd choose a random path?

Intuitively, yes, but, well,
mathematically, no.

Mathematicians apply
a path minimization

to analyze this kind of
predator-prey dynamic.

What exactly is that?

The snake pursues the mouse.

Mouse runs,
the snake is relentless

and tracks every step.

And when it runs into obstacles,

it finds the quickest, most
economical way around them.

Now using path minimization,
we can predict the snake's path

because the snake only has
one thing on its mind --

finding the most efficient
point A to point B

between it and its dinner.

So shooter number three is
just a lousy snake, or what?

Shooter number three's route was definitely
not determined by path minimization.

So... what then?

Maybe this.

Now we know that the school
uses RFID chip technology

to take attendance;

tells teachers when
students are in class

and when they're absent.

Keeps track of students
using a PDA.

Right. Names and locations of
the students show up on the screen.

The DMG kids, we know
they have the capability

to break into
the school security system.

Yeah, so why couldn't they
hack into the RFID?

They definitely weren't
taking attendance.

Charlie's right.

Can you bring up the model
for shooter number three?

Look at the behavior
in the model.

DAVID: He's letting the
students go right by him

without even taking a shot.

Because he's targeting
specific students --

the quarterback,
the skateboarder

and the swim team captain.

And the system would tell him
exactly where they are.

LARRY: Oh, that... no,
that's sufficient.

( African music playing )
Thank you.

So the last time
I had Ethiopian food

I was at a conference on
Bondi Accretion in Addis Ababa.

- ( laughs )
- What?

Oh, am I being tedious?

No, no, tedious would be
a week at Quantico

studying note-taking skills
at a crime scene.

Oh, speaking of which, I heard you
and Charlie went down to the school.

Yeah.

It was horrific.

I just kept thinking
all the while, you know,

if I could only
corral a wormhole

and go back in time,

just talk to these young men
before they did it.

And what would you say to them?

I would say high school
is ephemeral.

And I don't know if the meek
inherit the Earth,

but Bill Gates
and the Google guys...

you know, they did all right.

You seem to have done well.

No.

Well, now, but in high school?

Oh, I don't think you and I
would've been at the same table.

In fact,
I wasn't permitted a table.

I was kind of a mess
in high school.

Yeah?

That surprises me.

It was a surprise
to most people,

particularly my parents
who could, you know,

barely show their face
at the country club for a while.

Oh, no, country club.
You're one of those.

Social register, too.

You're full of surprises,
you know that.

So this FBI thing,

why did you become a G-man?

Well, it's a little more
complicated,

but I have three older sisters,

and I was my father's
last chance at having a son.

I could play every ball game
known to man.

As I got older, it just got
harder to switch gears.

In fairness, I should say that

the FBI has given me the
greatest sense of equilibrium

I've ever felt... on most days.

You do seem
a little distracted tonight.

It's just the case.

You know, Charlie's math proves
that our main suspect

does fit the shooter
profile for a school shooting.

But his math also shows us

that our shooter number three

wasn't on a killing rampage.

You know, I'm failing to see
the inconsistency.

The first two shooters fit
the profile of a school shooter.

They show unbridled rage.

This third shooter...

was calculated.

It was a planned attack.

It's indicative of
a whole other motive.

You know, in cosmology,

when faced with logical
inconsistencies,

I like to fall back
on an old chestnut:

if you don't like the answer,
ask a different question.

DON: 6:00 a.m.
I get a call from Charlie

saying we got some
new angle on the case.

It was something that Larry
said to me over dinner last night.

Wait, wait, you and Larry
had dinner last night?

Oh, God.
Moving on.

He just got me thinking.

You and I both have our doubts
that Dietrich is the third shooter.

Right.

So what if we need
to look at this in reverse?

What if we need to study
the victimology?

Shooter number three picked all
of his targets for a specific reason.

There has to be a reason why.

Oh, I see. So, what,
just have Charlie do

what he was doing with the suspects,
but do it with the victims?

Yeah. If we can find
the common denominator

it might take us back
to the killer.

All right, that's good.

Where'd you have dinner?

So I ran a cluster analysis

on the student files
of our three victims --

Rob Holt, skateboard dude;

Thomas Caballo, quarterback;

and Louis Ives,
swim team captain.

The two jocks share
numerous commonalities --

they're both seniors,

both captains of their squad.

What about skateboard dude?

His only commonality
is that his name appeared

in an investigation of steroid
abuse by student athletes.

He was a suspected supplier.

Some of the students
mentioned that.

The school investigated,
but nothing came of it.

Any other correlations?

All three names appeared in
a police report of a keg party

that got so rowdy
the neighbors complained.

However, there were a
dozen students on that report.

None of them were victims,

none of them had any apparent
relationship to the victims.

Yeah, but still, maybe something
happened at the party.

Yeah, something enough
to motivate a killer.

You got a list of kids
at the party?

- Can you put it up?
- Yeah.

We just need to find the
connection between these names

and one of the DMG kids.

Karen Camden.

Wait a minute, she was
on the police report?

She has a connection
to all the DMG kids.

Yeah, she wrote a story about
them for the school paper.

She knows them really well.

She knows they were having
violent fantasies.

Yeah, but why would she want
to take part in this attack?

I don't know, but it might
explain why they spared her,

not just because she gave them
props in the school newspaper.

Absolutely.
Maybe she's in on it.

MEGAN: Karen Camden purchased
a WiFi PDA three weeks ago.

Okay, so that would allow her
to track anyone in school, right?

Her credit card showed a bunch
of charges to a motel in the Valley.

The manager ID'd her
and Justin Price.

Oh, a pretty girl could get a
teenage boy to do a lot of things.

Especially if he's not
used to the attention.

And if he has the inclination.

I mean look at Pamela Smart,
she got one to kill her husband for her.

So what, she seduces Price,
uses him and blows him off?

She could've even gotten him to
shoot Paul Elins, his own friend.

She could've made up
the whole murder-suicide pact.

Probably knew he was fantasizing
about the shootings

and then just pushed him
over the edge --

and becomes the third shooter.

Why?
What's the motive?

Well, best guess,
we look at the victims.

The answer's probably
going to lay there.

School steroid scandal.

Article was written
by Karen Camden.

I thought that
investigation went nowhere.

No prosecutions, but
some of the team captains

lost their college scholarships.

Yeah?
Just to get even, huh?

Karen's not a violent person.

She'd never do
anything like this.

Yeah, but something happened
at that party, didn't it?

Something that changed
your daughter.

Mrs. Camden,
we have eight people dead

and 12 more in the hospital.

If you know the reason for this,
we need you to speak.

They raped me.

Becky was the one who set it up.

She invited me to that party.

Helped Rob Holt, Mr. Skateboard Cool,
slip something into my drink.

Then Jake Porter raped me

and the others watched
and took pictures.

Oh, God, Karen. God, honey.

I wrote that story
about the steroids.

They blamed me for messing up
their scholarships.

Why didn't you press charges?

They were the stars
of the school.

It would be my word
against theirs.

Karen, eight people are dead

that you went to school
with every day.

I'm going to need you to put
your hands behind your back.

( handcuffs click )

I'm sorry, Mom.
I'm sorry.

I'm sorry.

DAVID:
Jake Porter.

Yeah?

Take your headgear off,
tough guy.

We want to talk to you.

What's this about?

You're under arrest for the rape
of Karen Camden.

What are you talking about?

MEGAN:
We spoke to Karen.

She gave us a statement about
what happened at the party.

You're talking about the same
girl who shot up the school

with her psycho-geek pals,
right?

Everybody's talking about how she's
the one who engineered the whole thing.

You're telling me you
believe Karen Camden?

The girl's a whack job.

It'll be my word against hers.

MEGAN:
Yeah, would've been.

Except for Rob Holt's
cell phone.

Your moron friend took a
picture of you with his phone.

DAVID: Let's go. Turn around.

I'm not going anywhere
with you guys.

Yeah, you are.
You're coming with us.

Get off me, man.

Get your hands behind your back.

What is it with guys
and dirty pictures?

Stand up.

CHARLIE:
Where's Big Papa?

The caterer.

Ah, getting serious.

I just think he doesn't want
to have to cook, you know?

CHARLIE:
You never get enough?

DON: Look, what do you
want from me?

I like seeing how they spin it,
you know?

You think anybody really knows
how any of this stuff happens?

Definitely not.

I know that when I was
in high school, I was so...

uh, angst-ridden.

Yeah. But I mean,
you didn't shoot anybody.

No, but there were days
when I wanted to do,

you know, real...
real damage to...

to you.

To me?

Hey, buddy, take your best shot.

Come on.

Wait, I'll help you out,
I'll get on my knees.

Come on.

- I'm not a kid anymore.
- All right. Tough guy, let's go.

- Maybe we should step outside.
- All right.

- How about now? How about now?
- Let's go.

Come on.

You ain't got nothing.

All right, all right.
How about we just get pizza?

No, I don't want to go out,
man, I just got home.

There's a lovely pot roast
in the fridge.

It's a week old.
Come on.

How do you know that?

Of course.
You eat here more than I do.

I'll pay, how's that?
