CSI: Vegas

Mom, I know what's going on.

If you're running product for these guys,

I can't help you. Previously on CSI: Vegas...

They killed her, she's gone.

You cannot investigate

the death of a family member.

Jeanette Folsom. Who did it?

Raphael Tarquenio... is that your boss?

I'm not telling either one of you a damn thing.

I found the guy who did it.

Kahn Schefter killed my mother.

Josh was officially charged.

I'm looking for Raphael Tarquenio.

How long has it been?

Not nearly long enough.

I killed Kahn Schefter.

So we're supposed to believe

this was your idea?

I trust this concludes the matter.

Murder charges got dropped.

I want to say thank you

for believing in me.

I'm not sure you're gonna keep your job, Josh.

I saw that, Hernandez.

The four-month sleep regression is no joke.

Where's the cavalry?

Oh, should be here soon.

Till then it's just us

and the body.

- What do we know? - Not a whole lot.

A fisherman called 911

when he saw a stranger trespassing on the dock.

Which, in hindsight, may have been a bad idea.

Gunshots rang out on the call, then the line went dead and...

So did the caller.

Explains the dead body.

And what about the container?

Your guess is as good as mine.

Well, let's not guess.

What?

Whoa! Slow down!

Officer Hernandez died in an instant.

It's a miracle I didn't, too.

When I came to in the hospital the next day,

I was told that my camera,

the dead body and that yellow plastic container,

- all gone. - The whole crime scene was wiped.

Like it never happened.

Whoever it was got what they came for.

Case was never solved.

- What are you thinking? - The thing I've never been able to shake

is that I recognized that car that hit us.

It was part of this drug investigation I'd been working.

- Raphael Tarquenio? - One of his associates.

God, the man needs to go down, Max.

Lord knows.

- Joshua agrees with you. - Well, the problem is,

the SUV was never found.

We were never able to establish a link

between Tarquenio and the boat.

The man is my white whale, and I could never prove

that he even got onto the water.

Until now, maybe.

Look what I found at his house.

Boss.

Hey. You asked to see me?

Yeah.

I'm gonna go back to the boat, pick up where I left off.

I'll let you know when it's time to start the engines.

Go get him, Ahab.

So

These time cards are now your responsibility.

Happy days.

I know you and I knocked heads

over your idea to partner people up...

It's okay. No need to apologize.

I wasn't planning on it.

So, you partnered

Catherine and Beau, and Chris and Penny up.

Mm-hmm.

Any of them have a say in it?

No.

Do you care to reveal why

- those would be. - The best pairings? - I have my reasons.

Of course, I told them

that I drew their names out of a hat.

I didn't want anyone to object.

Okay, the pairings worked before you knew they were permanent.

Hmm.

Two heads are always better than one.

You'll see.

I'll get right on these.

You don't have to go.

I know things have been

complicated lately,

but you can stay.

I don't bite.

Yeah, well, I'd just keep you up.

I'm spooked about my date with Internal Affairs tomorrow.

Hey.

You have the Garrity rule.

Use it. You don't have to say a thing.

You shouldn't say a thing.

Yeah. Still, I should go.

Damn it.

Well, it was worth a shot.

I've taken a dozen shots

against Tarquenio.

I need one of them to land.

Are you okay?

Catherine.

If we're gonna be partners, you should know.

I-I don't do well with long silences.

I just took a breath.

Yeah, good. Good. Get it out of there.

Don't let it fester.

Okay.

You leave me no choice.

Fill the gap, I will.

You know, I think...

I think I could be a boat guy in my next life.

Although the idea of a life without socks freaks me out.

But, you know, the-the... the wind in your hair, the sun.

It's not really my thing.

Right.

Yeah, yeah.

It's downright depressing when you think about

what the drought's done to the waterline.

I mean, look at the dock here, this tangle,

the fishing line, it didn't look like that a few years back.

Here.

Look.

Today. 2019. Today.

2019. Today.

Y-Yeah, yeah, yeah. H-Hold on a second. Just...

What?

Is that a prosthetic limb?

What looked like the top of a bumper back then...

- No, it couldn't be. - Yeah, i-it could be.

Let's get it out.

All right.

Holy mackerel. It's a leg.

That is one funky plastic leg.

Wow. This thing's been in the lake so long,

it has its own ecosystem.

I need help figuring out how to clean it off.

Beau's still on the water,

seeing what else he can dredge up.

What are you hoping to find?

Proof that this prosthetic is somehow tied

to Raphael Tarquenio.

I'm convinced that he is connected to that dock

where this leg bobbed up.

Well, we can't use bleach as a cleaning agent.

No, it would destroy the algae

but also any remote chance of usable DNA.

And it'd require scrubbing,

which would compromise the integrity of

whatever evidence we do find.

No, we need something that's gonna break the bond

between the algae cells.

Maybe an oxidizing agent.

Something that causes free radical formations.

Sodium carbonate and water.

I'm so glad you two found each other.

Wait.

Look at that.

Something corroded the metal on the prosthetic.

But the plastic's totally intact.

Only a few types of chromic acids could have done this.

I wonder if the person attached to this leg

was dissolved the same way.

Dark.

Well, it might explain that plastic bin

I found on the boat that night.

Maybe all the contents were just dumped in the lake,

leg and all.

The, uh, leg's serial number was eaten away,

but, look, the atomic pattern was still down in there.

EBSD machine just gave us this.

Entering the serial number

into the national arthroplasty register,

and... Theresa Moren.

Looks like she's a dean at a prep school here in Vegas.

Or at least was.

So, what's her leg doing in the middle of Lake Mohave?

I don't know, but check out that caption.

"Farnsworth Prep's Jocelyn Tarquenio

sinks a three-pointer."

Raphael Tarquenio has a daughter who just so happens to go

to the school whose dean lost her leg?

I can see him raising Dobermans.

But a sweet little shooting guard?

And according to her obit, she died

in a scuba diving accident in Mexico.

The body was never found.

Check out the date. Dean Moren died five years ago.

That's the same week that I was almost run over by the SUV.

Best question in Vegas: What are the odds?

I didn't want to believe it, but
