BOY:
That was a weird movie.

Yeah, from the reviews,

I thought it was gonna be
more of a comedy, huh?

I thought it was pretty good.

BOY: Teenagers
like boring movies.

You only like cartoons.

No. I just don't like
boring movies

about people in love.
(kicks seat)

(laughs)

(laughter)

Can we get ice cream?

No, we got to get home.

Oh, come on.

It's on the way. Kind of.

MAN: Actually, bud,
it's-it's not at all.

You know?

However...

You know you want to.

Well, see, if you put
it like that, then...

(laughing):
Dad!

(laughing)

(gunshot)

Dad?

What was that?!

Take the wheel!

I'm trying!

Dad! Dad!

Watch out,
you're gonna hit that...!

Look out!

(tires squealing, horns blaring)

I got it!

- Dad?
- Dad?

Dad!

Lady luck.

Chance.

Randomness.

Human beings truly have
a hard time understanding it.

Raindrops fall randomly.

Now, which of these two images
best represents

raindrops falling on a sidewalk?

Is it image A?

Image B? Okay.

You're wrong.

Our brains misperceive
evenness as random,

and wrongly assume
that groupings are deliberate.

Because of this, people make
all sorts of irrational decisions.

Like, they-they won't work
in a high-rise building,

or they're afraid to live
in an earthquake-prone area.

And yet, a mathematical
assessment tells us

that you are far more likely
to suffocate in bed

than you are to die
in a terrorist attack.

You are ten times more likely

to die from alcohol than
from being in an earthquake.

And it is three times
more likely

that you will be killed
while driving

to buy a lottery ticket
than it is that you will...

that you will win the lottery.

(students laughing)

WOMAN:
They said he was shot.

Yeah, that's what we think.

Is there anyone who would
want to harm your husband?

No. No one.

I'm Don Eppes, FBI.

Marla.

So, do you know who did it?

Not yet, but-but
we're working on it.

I heard on the news there
were attacks on the freeways.

- Yeah.
- DAVID: That's true.

But we don't know
if those incidents are related

to the, uh, the attack
on your husband at all.

DON: Right, I mean,
what we'd like to do,

if we can, is just take a...

Excuse me.
Uh, Mrs. Kinkirk?

Yes.

Your husband's stable.

Thank God.

There are issues that
need to be discussed.

DON: All right. We'll
give you a few minutes.

We'll wait for you down here.

Oh, please stay.

Um...

DON: I'll take these guys.

Why don't we go
hang out there, guys?

Okay. Thank you.

Come on.
It's all right.

Your husband sustained
a gunshot wound to his head.

Luckily, the bullet did not
penetrate far.

It's lodged in the
right occipital lobe.

Our neurosurgeon is
confident that he can remove it

without further damage.

(crying)

So, can you guys tell
me anything at all

that you remember
from what happened?

I heard a loud crash
from the back.

I turned, and Pete was scared.

From the noise.

Right.

And then I saw the blood.

And I looked
where Pete was looking,

and I saw Dad was hurt.

So, what happened then?

I grabbed the wheel, and I tried
to keep us from crashing.

Yeah, well, that's smart.

You know, it's good thinking.

Now, right before the shot,

is there anything
that stood out?

Any cars or anything
that you might remember?

I don't know.

I think maybe
there was a white truck?

Okay.

I didn't see who was driving it.

Sorry, I didn't see it.

Is-Is our dad going to be okay?

Yeah.

And, you know, we're gonna do
everything we can to find the guy.

We got seven freeway attacks
in eight weeks.

Four people dead.

You okay?

Well, you know,
I just lied to those kids.

No, you made them feel
a little better, Don.

It's a tough time, you know?

I'm an idiot, acting like
everything's gonna be normal.

Those kids need to believe that
if they're gonna make it through.

Come on, Dave. Their lives
are never gonna be the same.

COLBY: There's no indication of enemies,
financial or marital troubles.

Witness testimony and
tips came up empty.

All right, so what
have we got here?

We got seven attacks
in two months.

What do you think,
Megan, serial?

MEGAN: Uh, if so, it's atypical.

All the MOs are different.

Yeah, the previous attacks
we had a wrist rocket,

thrown rock, brick, tire iron,

golf club, and then
a rifle shot.

Now we're looking at a
hand gun from close range.

Victims don't fit
a profile, either.

DAVID:
Yeah, it's rich, poor, Asian,

Latino, whites,
across the spectrum.

MEGAN: You know,
maybe instead of one sociopath,

we have a bunch of copycats.

Maybe there's no pattern at all.

MEGAN: That's what I just said, Charlie.
There's no pattern.

A single assailant,

or a bunch of copycats
both imply a pattern.

No, What I'm suggesting here is,

these groupings of shootings
might, you know,

very well be random.

Seven completely
unrelated attacks?

CHARLIE:
Sure. Consider this.

An MP3 player has a random
shuffle function, right?

It uses an algorithm to create a
random order to play the songs.

But when people listen
to their random shuffle mode,

they do perceive patterns.

That's just pure coincidence.

People swear their MP3 players
like to play certain songs.

I know mine has a thing
for ZZ Top.

CHARLIE: Right, right.
And that's exactly it --

that human beings perceive
patterns where there just aren't any.

All right, look, you know,
until we know different,

then we're gonna pursue these
as individual crimes, all right?

Hey.

Hey, Larry, do
you have a minute?

Yes, I have the eight
and a half minutes

it takes me to walk
to my office.

Now, if we need more time,

I guess we could choose
a longer route,

maybe stop and contemplate
the turtle pond.

Or we could just keep
talking at your office.

Yeah, it's not
as scenic, but sure.

You know, I'm finding
it a little strange,

uh, being a professor after
being a student for so long.

(laughing) Oh.

We have all been there,
my young friend.

I mean, I feel like I
should be going to lectures,

not giving them.

You know, I run
into former teachers

every day, who act
like nothing's changed.

That's why, you know,

people usually leave the school

where they earn their doctorate
and go off and teach elsewhere.

But, what, CalSci made you
an offer you couldn't refuse?

I don't know.

Maybe I would have been
better off on the East Coast.

No, no, no, no. Come on,
this is not about geography.

Listen, you yourself
must embrace this new role.

'Cause only then will others
be able to see you differently.

Wow.

Larry, even for you,
that was profound.

I guess you just caught me
when the caffeine was kicking in.

Come on.

MEGAN: I get the concept
of random clusters, I do,

but road rage is associated
with certain factors,

none of which are present
in any of these cases.

Wait. When you say factors,
you mean, like, what, like weather?

Yeah, and bad traffic, and
racial conflicts, and accidents.

Stuff that makes people tense
and angry.

All right, so,
it's not a typical streak.

No, and there's something else --
the youngest boy, Pete,

said he thought he
saw a white pickup truck.

Now he thinks he saw the same
truck drive by his house that morning.

What? A white pickup truck?

I mean, they're all over
the place.

He says both had a bobble-headed
hula dancer on the dashboard.

Yeah? What do you think?

I think he's nine, and he's been
traumatized, and he's searching,

but it opens up the possibility that
Jeff Kinkirk was stalked, you know?

That he's not a random victim.

All right. Well, look,
play both sides.

I mean, get a list of white
pickup trucks from the DMV

and-and work it with the guys.

What's the other side?

Well, the wife said she didn't
think the husband had any enemies,

but, I mean, maybe she was
hiding something from us.

Okay.

I took out the garbage,

helped Pete with his homework.

Everything's good at home.

(knocking)

DON:
Hey.

How's he doing?

They got the bullet out.

Now we just have to wait.

PETE: Did you
find the white truck?

Not yet, Pete,

but, I mean, we got a lot
of people working on it.

Guys, I need to speak
to your mom for a minute.

Is that okay?

DON: Your son Pete thinks
he saw a white pickup truck

the day of the shooting.

Now it's possible that that same
truck was near your house that day.

Someone was following Jeff?

Yeah.

Any reason for that?

No. I-I can't think
of anything.

Does your husband have
any problems at work,

or with neighbors,
anything at all?

No, there's nothing.

Anyone want to hurt you?

- Me?
- Yeah.

Not that I know of.

Marla, somebody tried
to kill your husband,

and, I mean, you have no
idea about who or why?

It doesn't make sense.

I mean, it could be
something minor.

Just even a-a fight
over a parking space.

That's just it.
You have to understand Jeff.

He'd let someone else
have the parking space.

(voice breaking) If he has a flaw,
it's that he tries too hard to be nice.

Okay. All right,
that's-that's all I need.

Come on. That's all right.

We were looking
for a white truck.

I've checked 177 so far.

I'm just also checking
some other factors.

Looking at traffic,
weather, employment,

time of day, day of the week.

Looking for a pattern in a
series of random events?

Oh, dear, Professor
Eppes wouldn't approve.

Okay, but here's the thing.

None of these
attacks can be linked

to the typical causes
of freeway violence

like bad traffic
and hot weather.

Gang shootings.

Seven random freeway attacks,

and not one of them
fits a profile

of a random freeway attack?

Yeah, I see what you're saying.

At least some should have
typical causes.

All we have are invisible
assailants and no motives.

Yeah, I mean, is it possible

for something to be too random
to be random?

CHARLIE:
I'm sorry, too random?

- MEGAN: Yeah.
- Too ran...

Uh, something can be
a little random.

Something can be very random.

But, no.

No, no, not, not too random.

Why?

Well, we're just kind of
assuming

that all these freeway attacks
are a series of random events,

but not one of them
can be linked

to the typical causes
of freeway violence.

You mean, like road rage,
stuff like that?

Yeah, actually.

70% of all traffic assaults stem
from arguments between drivers,

especially if one or the other

has something called
Intermittent Explosive Disorder.

Oh, we used to call that
having a screw loose.

(laughing) My dad had...
that screw loose,

but, uh, explosive rage
can be a little more serious.

People can erupt into violent
anger for seemingly no reason.

- I see what you're saying.
- Okay.

You're saying that in
this particular string,

there are none of
the typical causes.

Mm-hmm.
And what are the odds of that?

I would say
that they're not very good.

What if there's a pattern that
you're just not able to detect?

Hidden variable theory.

The idea that, that

nothing in this world
is ever really random,

that there is some influence

or some force
that we can't detect.

Isn't it, like, weird that none
of these attacks are typical?

Not one?

Weird, yeah, yeah.
Unlikely, yeah.

Impossible, no.

How's it going?

White pickups checked:
1,307.

Only about 162,000 left to go.

Oh, just think of the sense
of accomplishment

you'll have when you're done.

Right.
How you doing?

Looking for connections
between people,

you always find more
than you expect, you know.

Yeah, most of it doesn't
mean anything, though.

Two victims wore the
same brand of jeans,

went to the same college.

I got one I want
to take a look at.

These two victims
used the same car wash?

I want to get a
list of employees,

see if anybody has a record.

All right, I'll check
with the local cops.

COLBY: Victims number
two and number five,

Henry Rains and Cece Smith.

They're both patrons
of the Valley Car Wash.

DON:
Uh-huh.

Now, Rains got into a yelling
match with one of the workers there.

Two weeks later, he's
killed by a rifle shot.

What was the fight about?

He accused the worker of
taking money out of his car,

started getting loud with him,

so the car wash manager
had to call the cops,

but Rains split
before they got there.

- So who did he accuse?
- Calvin Oates.

Five years ago,
he's thrown out of a bar.

Comes back, fires a handgun
out the front window

from a moving car.

Car wash have links to any
of the other victims?

Still working on it.

All right, it's thin,
but go pick him up.

Manager special
today: $11.95.

Wax, underbody, tire dressing.

What air freshener?

We let the FBI garage take
care of all that, thank you.

Hey, we're looking
for Calvin Oates.

Oh, man, I just had
this suit cleaned.

(yells)

You, back up!
Back up!

Give me the bat,
give me the bat.

Thank you.

Next time, leave it
to the professionals.

(groans)

You're fired.

COLBY:
Come on.

Dude said I stole his money.

He started screaming,
coming at me.

I didn't do nothing.

When the manager called
the cops, he split.

So why'd you run?

I'm stupid.

(laughing)
Yeah.

When cops show up, I get lost.

I didn't think they'd bother
to chase me 'cause...

I didn't do anything wrong.

Well, that guy must have
made you furious.

He called you a thief

in front of your boss
and your co-workers.

Don't start the psych crap.

I've been in anger management
therapy for three years.

I know when someone's
pushing my buttons.

You got a lot of buttons, huh?

That therapy was

court-mandated as a condition
of your parole.

Yes, and believe me, I am now the
poster boy for anger management.

That must be one ugly poster.

Yeah, time cards show him at
work when Rains was shot, so...

You don't think he's the guy.

Either there isn't a guy...

And it's seven
unrelated incidents.

(phone rings)
...or, if it's one guy,

he's definitely a lot
smarter than this dude.

Hey.

All right.

We just got another one.

Well, there you go.

(indistinct radio communication)

Victim was a 28-year-old
computer tech.

Died instantly.

The killer had to lug
this cinder block

up to the top of
the tunnel entrance,

time the drop to hit a car,

and avoid being
seen by witnesses.

DAVID: That took work, planning.

I doubt it was vandals
or some crime of impulse.

You think she was
targeted or just unlucky?

DAVID: I think she
never knew what hit her.

Hey.

Pythagorean theorem,
law of cosines, metrics.

Equivalence principle.

Back to basics.

You know, I spent the weekend
at Politzer's

and he completely disassembled
my 11-D supergravity theory.

So here I am in ten dimensions
with two pea-brain solutions,

electrically and magnetically
charged respectively to the C-field...

You still sleeping
in your office?

Yeah, sleeping, living.

Cuts down
on the morning commute.

- You must find a new place to live.
- No.

- You can't live out of your office.
- No, I'm not going to be out there

choosing wall colors
and toaster ovens.

Look, I just want
to be thinking about gravity.

How do you expect
to have company over?

What company? Who?

Oh, I don't know. Who, I may -- who,
what, M-Megan, maybe?

Oh, oh, oh, listen.

If you propose to start
discussing my love life,

then I'm gonna find yours
to be fair game.

Ah, point, point.

Point to Professor Fleinhardt.

Hey, so, speaking of Megan,

she comes by the
house the other day,

wants to know if a
sequence can be too random.

It's funny.

I... fail to see
the humor in this.

Too random, you know, as
in excessively random.

Yeah, I'm, I'm following you.

I will now ask you
a series of questions

and I would like you
to answer simply

in the affirmative
or the negative.

Okay.

This discussion of randomness.

Was it somehow related
to the freeway attacks?

- Yes.
- Okay, might she be concerned

that all of the attacks
have different MOs?

Yeah, but...

And given seven random attacks,
all with different meth...

Eight now.

Okay, eight random attacks,
all with different methods.

I mean, might'nt she just find

the improbability of all this
just a little bit disconcerting?

Larry, you know, I can, I can
roll a pair of dice eight times

and never get
the same result twice,

and that would still fall
within the realm of random.

Yeah... but something
that doesn't repeat

is not by definition random.

- Shuffle mode.
- Hmm?

Shuffle mode.

Why am I such an idiot?

I think I've found new attacks.

These are insurance claims?

Mm-hmm.

There's damage reports
of objects striking cars.

Smart angle.

I have my moments, I think.

I was trying to find related incidents
that didn't result in any bodily injury.

COLBY:
Objects used include a rock,

a large slab of marble,

a lead weight, a steel pipe.

No injuries,
so no police report.

Megan.

Hey.

- I am so sorry.
- What's the matter?

You were right, I was wrong.

About the freeway attacks?

Yeah.
Remember shuffle mode?

Yeah, the patterns
that aren't there.

Controlled by an algorithm

that creates a random order
for the songs,

but the order isn't
really random

because the algorithm
won't ever repeat a song.

Just like the freeway
attacks don't repeat.

That's what I was saying!

So these attacks could be
the act of one person...

Who's trying to make them
look random.

Thank you.

Let me show you something.

All right,
here are five new incidents.

CHARLIE:
Five?

I didn't hear about that
on the news.

Oh, these cases haven't
been included before now.

Megan just found them.

All right, now, let's look at them
chronologically with the others.

That's a fairly regular pattern,
showing increasing frequency.

Thank you.

Okay, I'm going
to call this one.

I am 99% sure.

The varied methods are an attempt
to avoid any discernible pattern...

Which is in itself a pattern.

Yes, but what the perpetrator
can't hide is the intensity of his need.

The compulsion is growing,

so the time between acts is
getting shorter and shorter.

Classic serial killer.

We're looking at one guy.

You guys, check this out.

Just found that five
of the 13 victims

were involved in
serious injury accidents

over the course of
the last two years.

Oh, yeah?
Think that means anything?

I'm not sure if that would hold
true for any similar group or not.

Maybe call a CHP
accident specialist.

And the department of insurance.

Five of 13 --
that's less than half, man.

Yeah, I don't know if it's
just coincidence or not.

Well, let's find out.

So, Professor, you think
it's safe to drive, huh?

Even with this crazy person
out there attacking cars?

People get killed in
car accidents every day.

It's not like we worry about
that when we get on the road.

Uh-huh, speak for yourself.

Look, if you're worried
about the freeway killer,

you know, take the bus.

The bus does not go everywhere.

In case you missed it, we live in
Los Angeles, the city of the car.

You know, people in L.A. spend
100 hours a year in traffic.

100 hours.

That's four full days of waiting
for the car in front of you to move.

I'm getting road rage
just thinking about it.

But, seriously, you are twice
as likely to hit a royal flush

on your first hand of poker
than you are of being

a victim of this
freeway attacker.

Yeah, but I'm not afraid
of hitting a royal flush.

I'll still be around
to play the next hand.

You want me to behave
irrationally and tell you

that, yes, I would prefer
if my only living parent

stayed off the roads until
we catch this guy, okay?

There, I said it. You happy?

No! I have to drive
to Culver City.

My mall project.

I don't know why
I let you do this to me.

I should see it coming.

Yeah, but you never do.

Hey, look who's awake.

Hi.

Honey, this is
the FBI agent I told you about.

Anything new?

Well, what we're working with
is that in five of the attacks,

the victims have been involved
in a serious car accident.

So we're checking on the others,
but, uh... no?

Jeff hasn't had so much as a
speeding ticket since we were married.

No, I... I'm careful.

I worry about the kids.

A couple years ago,
I saw this...

bad accident where
this little boy was hurt.

It was terrible.

Yeah, you say you saw this?

JEFF:
Yeah.

An SUV ran through this light
and smacked a sedan.

I tried to help out
at the scene.

I gave a statement
to the police.

Jeff Kinkirk was the only
witness to an accident

that left a six-year-old boy
badly injured.

Now, Kinkirk says he saw the
boy's father run a red light.

Father said he didn't.

But both insurance companies
went with Kinkirk's account.

Well, a lot of people
witness accidents.

Yeah, but they don't all end up
with gunshot wounds to the head.

It's such a strange motive
for a series of attacks.

Yes, it is,
because serial attacks

generally have a sado-sexual
component to them.

The assailant needs to
see the victim suffer.

But not this guy.

He wants to inflict
serious damage,

but he's happy to do
it from a distance.

And he's not that intent
on killing every victim.

So how would
the profile break down?

Likely male,
and meticulous and educated.

History of road rage,
problems with anger.

Might have difficulty
holding a job.

He identifies with the victims.

He feels a sense of injustice.

He's probably a victim of
a violent crime himself.

Or someone close to him is.

Well, we could get a list
of major injury accidents

and cross-check them
against the victims.

DON: Yeah, we'll let Charlie
run whatever we come up with,

and get a suspect list going,
yeah?

Yeah, anything will help.

What do we have, five million
drivers in L.A. County?

The optimization algorithm
can be translated into software.

You know what?

I think Amita has it.

But there's stuff
in here we can use.

How's it going with Amita?

Huh? Oh, good, good.

No, yeah, she's -- I mean,

we're both pretty
busy right now.

- You know, she's a professor now.
- Yeah.

It's always tough, huh?

What's always tough?

The whole thing, you know?

It's just tough.

How you doing with Robin?

- Yeah, well, it is what it is.
- Yeah.

I know you don't like to talk
about who you're seeing.

Hey, Charlie, if I have
anything worthwhile to say,

believe me, you'd be
at the top of my list.

You know who else doesn't like
to talk about his love life?

Your boy Larry.

What do you know?

I know Megan thinks
he's beautiful.

(mouths)

What does he say?

It's difficult to decipher through
all the, you know,

the cosmological metaphors.

But he does really seem to
really like her, you know?

Hey, here we go, I found it.

All right.

(chuckles)
Okay.

(clears throat)
Before we run Amita's program,

I need to draw up
some parameters,

because there's a component
we're neglecting.

- What's that?
- Traffic.

I mean, this guy's
been attacking people

in broad daylight,
on busy roads,

running the risk of being seen.

Right.
No witnesses.

So he must be
planning carefully.

He probably plans escape routes.

Yeah, possibly.

All right, so if we can look at the traffic
patterns in the vicinity of the attacks,

that'll give us a chance to
guess at those escape routes,

which will give us a more general
idea of where he goes afterward.

Right, 'cause he'd definitely want to
avoid traffic in each instance, right?

Oh, yeah. Oh, yeah.

No, traffic flows
just like any other, you know,

dynamic fluid flow
in a closed system.

You know, it's like the
water in your house.

Water flows due to
pressure and release.

What is the optimum
length and width of the pipe?

What are the number of branches?

How many release points
are there?

I mean, it's a little more
complicated for traffic,

but partial differential
equations can help us

calculate the optimum number
of lanes, on and off-ramps,

signal synchronization.

And I can use data
from road sensors,

traffic cameras and
satellite imagery.

I mean, hell, I can even factor in the
street light algorithms used by the D.O.T.

This is fairly high-level math.

So ten out of 13
have been involved

in some sort of
serious injury accident.

Six are directly involved.

There's a lawyer
for an insurance company,

two accident witnesses
and a tow truck driver.

And we're still trying to
connect the last three.

Yeah, unfortunately,
this guy works to a schedule,

and, you know, he's due now.

(sighs)

Oh, look!

It's CalSci's
live-in cosmologist.

Listen, don't laugh.

I think that couch of mine
has finally fused my vertebrae.

What's going on, Larry?

Is there something you
want to talk about?

No.

I find any discussion
of my inner feelings

to be potentially catastrophic.

It's like a star --

burns up all of its own fuel

and then finally collapses
in on top of itself.

I was just trying to be
supportive here, Larry,

not destroy a solar system.

CHARLIE:
Who needs a caffeine fix?

LARRY: Hey, you know
what Rényi said?

He said a mathematician
is a machine

that turns coffee into theorems.

(Charlie chuckles)

Thank you for getting
on this so fast.

Hey, I don't want to be shot

or struck by a brick while driving
any more than the next person.

You know, I guess there's
nothing to be done about meteors --

well, just yet.

CHARLIE: No, Larry,
even the FBI can't stop meteors.

No, not yet, but someday.

We'll have plasma cannons,

steam rockets.

Anything interesting?

Well, I loaded the data
into the modeling software.

It should produce a clear graphic
of the flow of traffic after the attacks.

I'll put it up on
the LCD. Great.

Also, I compressed time,

so that 30 minutes
plays in 30 seconds.

And what's this?

It's a traffic anomaly -- a
street adjacent to the freeway.

Pull it up.

(beeping)

Huh.

CHARLIE:
Look at that flow.

Optimized in one direction,

all the cross streets
are backing up.

Pull up another one.

(beeping)

Yeah, there it is again, wow.

And this timecode is telling us
that this is after the shooting attack.

It's like someone opened up an escape
valve for traffic coming off the freeway.

It's more like an escape route.

(horn honking)

MAN:
Come on! Get out of the way!

(horn blaring)

WOMAN:
Move out of the way, lady!

(siren whoops)

(low, indistinct radio
communication)

Ma'am?

(tapping)

Ma'am, roll down your window.

MEGAN:
Kathryn Krager.

She's 46 years old, she
has two teenage children.

She works for the
City of Bellhaven.

Notify the family?

CHP's at the house now,
actually.

All right, we got to see if she fits
the traffic accident scenario, right?

This is the second gunshot wound
at close range.

That's new.

All the other ones were
different forms of attack.

What? Different guy?

No, I think it's the same guy,

he's just not afraid
to repeat himself now.

Yeah, he thinks
we can't catch him.

And he might be right.

Come on, you know
we can get this guy.

All right, if you say so.

And how about
the next one on deck?

What's going on with you?

Nothing.

No record the victim was
ever in a traffic accident.

That was Krager's boss --

the city manager for Bellhaven.

Said that two years ago,
a neighborhood submitted

a petition for a light
at a blind intersection,

and Krager was in charge of
overseeing the traffic budget,

and she turned
down the petition.

So she wasn't actually involved
in an accident herself.

Somebody might blame her
for causing one.

Right.

So an accident happened six
months after Krager denied

a request to have a traffic
light put at this intersection.

Three people in two vehicles.

One person survived:
Brennon Sommers.

His wife, the driver of the
other vehicle died at the scene.

And Sommers suffered
a head injury.

Anger and impulse
control problems.

He's lost his job,
he's living on disability.

He's been arrested
twice since the accident,

although the charges
were dropped both times.

Well, I can see where
he might blame Krager

for not putting in
the stoplight, right?

COLBY: Yeah,
but she wasn't the first victim.

I mean, why kill
other people first?

MEGAN: Well, maybe his first
victim set him off some other way,

and then once he got going,
he went back for Krager.

Brennon Sommers!

COLBY: Put your hands
up and walk over this way.

What is this about?

Put your hands up and
walk over this way.

Get your hands up!
Turn around right now!

What?! What?!

I was an architect.

And now...

I can't concentrate.

I can't read for more than
a minute at a time.

And that's Kathryn
Krager's fault?

Who?!

Who is that?!

I think you know.

I mean, you wrote a letter
to the L.A. Times,

because Bellhaven wouldn't
put in a traffic light.

She was behind the decision.

I blamed the city, yeah,

but I never knew
who made the decision.

And you do get into
a lot of fights.

Maybe because people
don't treat you fairly?

No, because I have anger
and impulse problems.

It comes with
the frontal lobe damage.

I'm trying to deal with it.

By seeking out
people who hurt you?

No! Nothing like that!

I'm in group therapy,
that's all.

I used to be a nice,
easy-going guy.

Hard to believe, huh?

Doctor says he couldn't
lift a cinderblock

or fire a weapon accurately.

Found no firearms,
no evidence at his house

linked to any of the crimes.

He's close but not our guy.

Close?
What do you mean?

Somebody like him, you know?

More capable or angrier.

Hey, you guys, Charlie's got
something he wants to show us.

Hey, Chuck, what do you got?

Hey, I've got probable
escape routes

gathered straight
from traffic data.

Now, these red routes have
the highest level of probability.

Yellow routes, next highest.

- Blue routes, least likely.
- DON: Okay, good.

Why don't you guys
go check 'em out.

You know, see if you can find
a witness, right?

All right.

Here you go.

Field trip. Love it.

You drive, I'll navigate.

I remember it was
the day of the shooting.

I'd just heard the report
on the radio;

couple minutes later,
this truck blows by.

What made you notice the truck --
was it speeding?

MAN:
No, that's not unusual.

No, it was that, uh,

I see this pickup,
you know, coming up fast,

and then the light goes red.

Wait, wait, did you say pickup?

Yeah, yeah, white pickup truck.

MAN:
The light's red, like I said,

and he didn't slow down,

so I figured
he was gonna run it,

and then it goes green again,
after only a couple seconds.

You're sure about that.

It's my job to watch the light.

Can you describe the truck --

maybe you got a look
at the driver.

Mm... it was a late-model,
American make, I think.

White, like I said.

I couldn't see
the driver, though.

It was just a white dude
with sunglasses.

Okay.
Anything else?

Maybe there was something
on the dash, possibly.

Well, there was,
now that you mention it.

I couldn't see
what it was, though.

All right, thank you.

Infamous white pickup.

Sounds like the one
Jeff Kinkirk's son said he saw

just before he watched
his father get shot.

Yeah, the crossing guard's story
about that light changing --

you thinking what I'm thinking?

Yeah -- that our killer
somehow figured out

how to tamper with the lights?

Yeah.

Hey, you.

Yeah, aren't you supposed to be

at the string-theory
symposium at USC?

Now, how do you know
I'm not there?

One of those kinds
of days, is it?

Oh, well, aren't they all?

Larry... is everything
all right?

Everything?

Well, I'm not sure that I can
account for the state

off all matter, but...

You know exactly
what I'm talking about.

Stop trying to Fleinhardt
your way around answering me.

What is it, exactly,
that you want to know?

If sleeping in your office

and missing an event important
to your field of study

constitutes something
that I need to...

be concerned about.

Well, as I previously explained,

I'm sleeping in my office

because I don't wish
the distraction

of finding and furnishing
a residence.

Fine. Fair enough.
The symposium?

I'm hoping to be unavailable,

due to a pressing social
engagement.

You're choosing dinner with
Megan over string theory.

The two are not incompatible.

But thank you.

- For what?
- For looking after me.

It's so good to know that if I
ever stray from the rational plane,

you will be there to accost me.

(phone ringing)
Any... anytime. Hello.

Oh, this modern age.

We think the freeway killer
uses a device like this.

It emits a pulse
of infrared light,

causes traffic lights to change.

They're legal only
for emergency vehicles.

All right, well, that explains
he's getting through traffic, then.

Disrupting traffic lights should
leave a record in the system --

times and places.

There's cameras all over
Los Angeles --

on buildings, at intersections,
at ATM machines.

Okay, so we can check
the locations and the times

against the webcam logs...

Use them to get a photo.

What do you think are
the chances of that, though?

More cameras, better odds.

What do you say, guys?

Hey. All right, so
here's what we got.

We've been through hundreds of
webcams at intersections

indicated by Charlie's analysis
of traffic light disruptions.

We got this traffic webcam from
La Brea and the 10 freeway,

at 15 minutes after
attack number nine.

COLBY: And three seconds
before he drove through that light,

it was hit with
an infrared pulse.

No license visible, no way to
identify the truck or the driver.

And this? What's this?

Oh, that's some sort of decal.

Pulling together a lot of string

that the crossing guard witness
saw the killer...

That the guy in this photo is
the one who changed the light.

Maybe you're right -- I mean,
maybe that's our guy.

TECH:
We're getting something.

I'll flip it around
and print it out.

Looks like "HTSU."

"Head Trauma
Survivors United."

Yeah?

Yeah -- Brennon Sommers,
the guy we suspected,

I think he's part of
their Northridge chapter.

There's something on the bottom
of the decal that's not quite legible.

Well, it could be Northridge.

Now that would not be
random chance.

COLBY:
So far, we have eight current

and former members who we can
link to freeway attack victims.

Ran the members through DMV.

Two have white pickups,
one's a 74-year-old lady,

the other is Mitchell McKenzie.

38, he's a home contractor.

McKenzie was in a motorcycle
accident a year ago.

He suffered a head trauma.

Two months after he
joined the support group,

the freeway attacks started.

Well, that must be it, right?

That must be how he's choosing,
is through the support group.

His accident was a hit and run,

So he's got no target
for all the rage.

He could be acting on behalf
of the other victims.

That's not the kind of support
anybody expected.

Mitchell's close to many
people in the group.

It's common for trauma victims

to feel like nobody understands
what they've been through,

except other victims.

And, Dr. Bird, do you discuss
the freeway attacks in your group?

It's come up in meetings.

I remember I made
a note about it.

What was your note?

Mitchell talks a lot
at meetings,

has an opinion on everything.

But on the topic
of the freeway attacks...

he's been quiet.

Thank you.

Excuse me.

Eppes.

Don, I think McKenzie
could be the guy.

We just got a hit
on his credit card.

A gas station in Long Beach.

So I got David, Colby
and LAPD on their way.

(siren approaching)

(glass shattering)

Come on, man!

(tires screeching)

(indistinct radio transmission)

(yells)

Come on!

(sirens blaring)

Get out of the way!

Get the hell out of the way.

Get your hands on the wheel!

- You! This way!
- Get your hands on the wheel!

(indistinct shouting)

I'm only trying
to do what's right!

Innocent people hurt and killed!

And those responsible
just walk away!

Somebody has to pay.

That's all I do.
I make things right.

I make things right.

What are you sitting
in the dark for?

Just thinking.

Thank God you caught
that guy, huh?

Five deaths, six people injured.

And tomorrow I got 12 new cases.

Yeah, you're having a lot
of tough ones lately.

Maybe you should think
of taking some time off.

Yeah, don't I wish.

Donny, it's not good
for you to get this way.

Oh, Dad, what are you talking
about? This is the way I am.

No, no, Listen to me. Donny...

Look, it's just, you know,
sometimes...

(door opens)

Hello.

Hey, Don.

Glad you're here.

Found something interesting
that I want you to look at.

Oh, yeah? What's that?

You know how I thought that all the
freeway attacks were a random series?

Yeah.

They weren't. They weren't.

Because, yeah, McKenzie was
behind all of them,

but he didn't actually
start the sequence.

What are you talking about?

A hit and run driver started the
sequence when he hit McKenzie.

The head injury
the McKenzie sustained

left him unable to control his
impulses, control his rage...

Oh, come on, Charlie, the man
is still responsible for his actions.

Yeah, of course.

Except that the guy that hit
McKenzie was never apprehended.

He totally got away with it.

What, is this his accident report?

Yeah, Megan called
the CHP for me, and I just...

I thought it was something
you might want to look at.

Yeah, I think I see
where you're headed.

What? We got
his tire treads,

paint and metal...

Yeah, there's tons
of information.

I mean, I can help
you with this.

DON:
Yeah, yeah, yeah.

Yeah, Charlie.
This is good.

There's enough information.

- You got a pen?
- Yeah.

We can narrow down
the suspect list.
