CSI: Vegas

All right, keep up the good work, Cinco.

Hey, Tres, how's it going there?

Cuatro, what just happened?

What the...?

Oh, hold it.

Oh.

Hey.

We don't have to be... Look, I know we're not together anymore...

Good morning. Hey.

I'm sorry.

No...

How have you been?

I'm, uh, I'm fine.

We should still be able to talk, you know?

Share stuff.

It's not like I'm still reporting on you guys

to Internal Affairs anymore.

And the venue was so great and...

But there's no pressure to set a date, though.

No pressure at all.

I was just writing in the future log

in my bullet journal.

Maybe you're not a "long-term plan" kind of gal.

Also cool.

Everything okay?

Did you just hear what Chavez said?

Uh, uh, no, no. What? Detective Chavez.

She just said it's not like she's still reporting

on us guys to Internal Affairs anymore.

Not like she's still, as in she was.

Chavez was reporting on us to Internal Affairs.

All of us. In secret.

Probably this whole time.

Which is... bad.

I-I can't believe this. I got to go.

Yeah.

Smile, Allie, you're on camera.

Don't get too excited. Some kind of power surge

knocked everything offline.

Cameras, motion sensors,

and most of the robots.

Most of the robots?

Mm-hmm. They cleared them all out for us.

And apparently they call this place a "dark factory."

Machines run all night,

and they set up for human workers the next day.

They weren't just using the machines.

Look, they were building them.

So, robots building robots.

Robots all the way down.

The overnight shift is maintained

by just one man. Well, it was.

Robert Cuevas, 48.

Worked in this factory the last eight years.

Contusions here and here.

Probably some more here.

So cause could be blunt force trauma.

Hey, what do you make of this?

Whoa. Whoa?

What's whoa?

This spatter is all over the map.

It came from only a handful of impacts,

but the size of the blood droplets...

These are around four millimeters.

These are maybe two, 2.5.

All normal.

Those are one millimeter.

Less than a millimeter means really fast,

like a bullet or a table saw.

But the pattern is similar to a blunt impact.

Like a punch. Hi.

Hi there.

Sorry to bother. Sorry.

I'm Sabrina, Mr. Thomas's assistant.

Mr. Thomas?

The owner of this company, among many others.

I was asked to let you know that the techs

who found Mr. Cuevas's body are here

if you maybe want to talk to them.

Yeah.

Hey.

A man lay dying with all these machines

moving and working all around him, huh?

It's kind of dehumanizing.

Wait a minute.

Is that blood?

Yeah, there's more here.

Allie.

Are those hairs?

Yep.

Same color as our victim's, right?

Well...

Did they go out that way or...?

Let's see.

Look there. It's going this way.

That's a bit bizarre, right?

Hey there, little fella.

So, you didn't kill him, did you?

Hey, where's your little bestie?

Beau and I drove separately.

Believe me, we see enough of each other

under Allie's partner system.

You don't really think that a robot killed that guy, do you?

Well, the experts say it couldn't happen.

RGB/lidar array combined with a proximity guidance system

means it can see perfectly.

It couldn't collide with objects.

We built it to not collide with objects.

Thank you for that very thorough explanation,

which wasn't an answer to my question.

Is it literally impossible

for one of these machines to hurt someone?

We've been building these guys for six years.

Never had an injury.

Well, Bill burnt his hand

on a soldering iron last month.

We've never had a robot-related accident.

Okay, what if it wasn't an accident?

Could someone tamper with one of these things

to make it more dangerous?

Well, I ran diagnostics on the bloody one, uh, Ocho.

Uh, Ocho's his name because he's the eighth robot.

Would it surprise you to learn I speak Spanish?

Right.

Well, he's as good as he was fresh off the assembly line.

Uh, nobody's tampered with him.

But the robots can be controlled. Right?

Like a person drives a car.

Who here could get behind the wheel of one of these things?

Our bipedal hydraulic humanoid robots

use keyframe programming and a suite of AI tools

to operate.

That takes experience, but,

I guess a lot of the folks who work here could figure it out.

At least in theory. I just think...

Hey, hey!

Hey, hey.

Hey, what do you think you're doing?

That's proprietary technology.

Well, this proprietary technology

is at the very least a murder weapon.

Or an actual murderer.

Either this man-made machine killed Mr. Cuevas...

...or that's what somebody wants us to think.

Either way, some person is responsible.

Ocho and the blood spatter--

that's all the evidence we've got,

so, yeah, he is coming with us.

Beau, that Roomba's headed toward my blood spatter.

No, no-no-no-no, no-no-no-no-no-no-no-no.

I got it. I got it.

I'm fine.

Just weird doing an autopsy

where the killer might actually be in the same room as me.

Max and Allie are here.

Love you. Uh, listen to your physical therapist.

Your sister doing better?

Comes home Friday.

The doctors thought it would take much longer

to bounce back from thallium poisoning,

but they are happy with her progress.

That,

and also she won't stop critiquing

her physio's understanding of anatomy, so...

Sounds like she's back to normal.

So, Mr. Cuevas.

Cause of death is clear.

Blunt force trauma to the head, neck and chest.

Manner of death, on the other hand,

is trickier to define.

Not natural, not suicide, which leaves us with accident

or... Homicide.

Robocide, though, right? Mm-hmm.

"Cide" meaning act of killing,

"homi" meaning by human, whereas...

You think Ocho is responsible.

Almost missed it in the examination,

but I caught it in the X-ray.

Now, this is a bit of our victim's skull,

cleaned and lit obliquely.

You can see the impact here.

Something hit him hard,

leaving this very distinctive wound.

Now, this is the robot's hand.

You see the manufacturing defect,

this little curve?

I'd call that a match.

This robot hit our victim on the head

very hard. Oi.

I have something here.

There's something reflective in this wound.

Some kind of piece of glass.

I didn't notice any chipped or cracked glass on Ocho.

Maybe he was struck by some secondary implement.

A bottle or a drinking glass?

Remember that one time, with the snow globe?

I don't know what a snow globe's doing in a robot factory.

Find out where the glass came from.

And I'm gonna get together with Folsom

and try and recreate his attack.
