FBI

Sarin gas is a valuable commodity

to a particular group of people.

You mean terrorists.

They likely intend on using that sarin gas

in New York City.

Unless we find them.

We need to wait for the protective gear,

and you have to trust me on this one.

Change of plans, we do not have time

to wait for SWAT.

We need you to make entry now.

No!

No, no, no, no!

Gotta get me out of here. - Stay with me.

Maggie!

It's not even like she had a fever or anything.

She was just coughing.

Her parents are being cautious,

which I, for one, appreciate.

Can you pass me the egg rolls?

Look, I know you're disappointed,

but you can go to Rachel's next weekend.

I'm with Dad next weekend.

I'll talk to your dad, okay?

But for now, can we try to have a good time?

I got you cookies from Weaver Street Bakery.

The double chocolate ones?

Mm-hmm.

Oh, my God. Maria, no!

No.

Get off. No!

Brooke, honey, wake up. - What's going on?

- Wake up, we have to go. - You're scaring me.

- Get in the closet. - Mom.

- Shh. - Mom!

Ah!

Two of your agents were exposed to sarin gas.

Agent Bell is still undergoing treatment for nerve damage,

which I'm hearing will require months--months of rehab.

You want to explain to me how the hell we got here?

There was an accident at the lab,

and the doors sealed automatically.

Right.

What were your agents even doing in the lab

without backup in the first place?

We had evidence that the suspect

had been tipped off; we had to confirm

that he was still on premises.

Without Swat? Without HAZMAT?

Knowing there could be chemical weapons inside?

- We were moving quickly. - Yeah, too quickly.

You nearly cost your agents their lives.

I made the best decision I had

with the information I was given.

Yeah, the problem is, these big, impulsive decisions

are quickly becoming your MO.

Excuse me?

You're getting a reputation

for being a bit of a cowboy, Isobel.

What does that mean?

It means I'm getting calls from the deputy director

asking me if he should be concerned.

Look.

My advice?

Take it easy for a while.

Okay, you played the game.

You beat out the boys,

made it to the top of the pecking order.

You don't need to try so hard to prove yourself anymore.

Understood, sir.

So have you guys talked to Maggie?

How is she doing?

I went to the hospital yesterday.

She's awake. There is a lot

of residual nerve damage, and she is looking

at a lot of physical therapy, but Maggie's a fighter.

She's gonna get through it. - Good.

- Hey. - Hi.

All right, folks.

Uh, heads up, this is a rough one.

Last night, morning show host Maria Blake

was brutally stabbed to death in her house in Boerum Hills.

Her wife Olivia was also attacked,

but she survived.

She's in critical condition at Hope General.

Olivia's ten-year-old daughter called 911.

Was she there during the attack?

Uh, yeah, she was hiding in a closet.

Yeah, NYPD thinks the MO of the attacker

matches two others across town.

They are asking for our help

in a potential serial killer case.

What do we know about the earlier murders?

First victim was 38-year-old

real estate broker Chetna Burman.

Killed at her brownstone on West 73rd Street

sometime around 2:00 a.m. on March 20th.

Two weeks later, bank president Jamie Merritt,

42, was found dead with similar wounds

at her place on West 87th.

Those are Upper West Side addresses.

So the Blakes in Brooklyn would be a departure.

Yes, but the other case markers all line up.

Like townhouses broken into late at night,

powerful women in their 30s and 40s

being attacked with a knife, so.

Yeah, let's get to work, huh, people?

You four want to head to the scene,

see what you can dig up?

- Oh, welcome aboard. - Thanks.

So, you're, uh--

Oh, filling in for Maggie temporarily, yeah.

I got the call this morning,

so I didn't have a chance to tell you,

but, you know, don't make it weird.

This is a nice house.

The family doesn't have a security system?

House has one, but it doesn't look

like they had it set up yet.

Neighbors said they just moved in,

had workers in and out.

- Any sign of forced entry? - No.

Back door was unlocked when we arrived.

Got markings around the keyhole.

Looks like the guy must have picked the lock.

We're gonna need you

to touch base with the neighbors again

to pull their security footage.

You got it.

I know you're just doing your jobs,

but she's been through a lot.

Between the divorce,

her mom getting remarried, and now this,

it's just--I mean, it's--

We'll keep it brief, okay?

We just want to ask her a few questions.

Of course.

Now, Brooke, honey, I, um--

I need you to tell them what you told me

about the guy that you saw, kay?

I'm not sure, but he kind of looked

like the man who worked on our house.

He had the same kind of boots on.

I think she said that, uh, the guy was arguing

with her stepmother, Maria.

Okay, uh, when was this, Brooke?

A few weeks ago.

And do you remember what they were arguing about?

What did the man look like?

He was tall.

Do you know how old he was?

Or what color skin he had?

He was about your age.

And he was Black.

Do you think you would recognize the man

if we showed you a photo?

Yeah, I think so.

Yeah? Okay.

Isobel Castille?

SSA Deon Marshall

from the Behavioral Analysis unit.

I've been assigned to your serial killer case.

Well, thank you, but I did not request

a profiler on this case.

ADIC Hawkins is an old friend. He asked me to advise.

I'm sure you have a handle on it.

Just here if you need an extra set of eyes.

Okay. Welcome aboard.

Okay, listen up, everyone.

This is Deon Marshall with BAU,

he will be assisting us in this case.

Great. So, uh, the killer

did not leave and forensics on the scene,

but we just got the ME's report.

The knife wounds found on Maria's body

are similar to those found on Merritt and Burman,

so it seems like we are looking for the same killer.

Have you been able to identify

any connection between the victims?

We're still digging into their backgrounds,

but so far, no. No clear nexus.

Hey, I just talked to Scola.

ERT thinks Maria's wedding ring was stolen.

There are lacerations on her finger

like it was forcibly removed,

and they can't find it in the house.

Did any of the other victims have jewelry taken?

Yeah, uh, Burman wore a diabetes bracelet

that NYPD never recovered.

No, there's nothing about missing jewelry

in Merritt's file, though.

It's not unusual for serial killers

to take jewelry as trophies.

Yeah, Kelly, you want to make sure ERT is doing

a full inventory at Merritt's? - Got it.

Listen, did we ever alibi out the ex-husband?

Uh, yeah. He was in Philly overnight

on a job interview. - And we confirmed it?

A theater there confirmed he had an interview

to be their technical director,
