BERNSTEIN: 16 years on the job and this is the most bizarre thing I've ever seen.
CAINE: It's a new one for me, too.
Cross-country runner found him when she was training.
Thinks he might be a professor at the university.
So, no ID yet?
No, we're working on it.
Auto-erotic?
I don't think so.
Too much violence.
No way is it suicide.
It's not a suicide.
You see these knots?
See how elaborate this is?
Where does this leave us now?
Up a tree.
♪ Yeah! ♪ Captioning sponsored by CBS and CSI PRODUCTIONS
♪ We don't get fooled again ♪ ♪ Don't get fooled again ♪ ♪ No, no! ♪
( shutter clicking ) Rust has spread to the tree.
This block and fall's been here a while.
A pulley system.
Now what is that doing here?
Looks like trauma from head to toe.
You think it was inflicted before or after he was strung up?
WOODS: Don't know... yet.
Fabric and blood.
There's an awful lot of foot traffic for such an out-of-the-way place.
The campus isn't far.
Maybe the kids come here to party, make out.
You got something, Speed?
Yeah, take a look at this.
Is that canine?
Some kind of animal sacrifice?
Weird cult?
It's in the same shape as our victim-- mutilated and dead.
I got an ID.
Adam Metzger, cultural anthropologist.
Teaches at the university.
He just took a permanent sabbatical, didn't he?
WOODS: Eyes open.
Implies he died quickly.
But his wounds don't make sense.
I've got signs of retinal burn.
You mean like snow blindness?
Yeah.
How could he get snow blindness in Miami?
His eyelids are glued open.
( terrified groaning ) Somebody wanted to make sure he saw something.
Or, based on the damage to his retina...
Saw nothing.
( sighs ): All right... one wound down.
Want to get started?
Yeah.
Puncture wounds, six inches deep.
Size and shape of an ice pick; nine total.
12-inch contusions indicating blunt force-- eight such wounds.
One- to two-inch cuts.
Could be a razor blade-- 14 of those.
Oh...
Are those needle marks?
Puncture wounds.
You said you were thinking cult?
Maybe. You mean like a life-size voodoo doll.
Counting those as one we have a total of 62 wounds, all antemortem.
All that blood, and yet he didn't die of exsanguination, did he?
No, whoever killed him managed to avoid every major blood vessel.
62 wounds, and not one of them meant to kill him.
Cause of death was asphyxiation.
So, he was mutilated for who knows how long.
This looks to be one of the oldest wounds.
Antemortem abrasions have four stages of healing: scab formation, epithelial regeneration, hyperplasia and regression of granulation tissues.
These scrapes were at the second stage.
So, his body went through four to six hours of healing.
Or four to six hours of torture.
Hey.
How you doing?
Underwater Recovery called with a stinker.
Classic insurance job with a twist, I'm sure.
Bring you back to the days when you were drinking murky canal water and dining on rusty car parts?
Yeah, don't knock it.
Underwater Recovery gets all the chicks.
No skid marks.
Which means it wasn't an accident.
Which means somebody probably pushed it in.
Eric Delko.
( laughing ) The man who went on to bigger and better things.
Hey, how are you, man?
I'm still wet, man.
Yeah, you are.
Somebody called in a shadow?
This was what we got.
Windows wide open.
It looks, uh, it looks hinky.
Well, she sunk fast.
Silt layer's pretty thin.
Hasn't been here long.
Three, maybe four weeks.
Aren't you supposed to be on the other side of the law now?
Why don't you get on the other side of this car and help me out with this?
Oh!
Ah!
Yeah, no problem.
Look, I'm... going to go secure the tow.
Bacteria's filled his body with rancid gas.
Ah, guy's twice his normal size.
Yeah, it's a trunk job. It could be a mob hit.
Yeah, or drug related.
We'll know more once we get him out.
Yeah, could you see if there's any more surprises in that trunk?
Yeah, we got to be really careful with these guys.
It's really easy for them to burst.
Oh, whoa, Jerry, whoa!
Oh, relax!
Okay, I think I might have it.
Handcuff knot.
Military.
Used to tie prisoners.
And professors.
191 countries in the world seven-eighths of which have armed forces.
Well, at least that narrows it.
Speed, what have you got?
DNA results from the fabric at the tree.
The blood doesn't match the professor's.
I don't know, maybe it's our killer.
Or killers.
We've got 13 different types of wounds here.
That means 13 different weapons.
Not yet identified.
Take a look at this.
What is that, a tattoo?
It's a contact burn; look closer.
Streaming nuclei.
Those are micro-blisters normally associated with an electrical burn.
Now, I thought taser but the marks are too large.
Maybe an electric baton?
Possibly.
What part of the body are we looking at?
Scrotal sack.
13 weapons, 13 wounds... 13 different killers?
The appropriate number for a cult, right?
HERNANDEZ: People's feelings for the professor ran pretty much hot or cold.
No in-betweens with that guy.
Start with his students.
Loved him; thought he was a genius.
Wish I could agree.
Okay, so that's where the cold came in.
Look, I'm sorry to hear that Adam was murdered but in a way, I'm not surprised.
Why is that?
The guy was a whack job.
METZGER: Hatred is inherent.
It is instinctual.
For every student that loved him there were two parents and another professor who couldn't stand him.
He was as controversial as they come.
Man is not man without hate.
Tell me more about his extreme teaching methods.
Sure, let's see.
He came to class one day dressed as Hitler.
Wrote serial numbers on everyone's forearm.
A couple of weeks ago he brought in a Grand Dragon of the KKK and a Colombian prison interrogator to give guest lectures.
Pain moves us into the process of becoming whole... healthy.
The other day I walked in he was showing some home movies.
Slaughter, torture, lynchings, you name it.
Pain is necessary.
Pain is vital... for survival.
We're going to need to talk to his class.
On the way there now.
One more question, Dean.
How many students did the professor have?
13. Why?
13.
I have a very interesting lesson plan for today's class.
It's called How to Take a DNA Swab.
So who's going to be first?
CAINE: Ned Sante, you're here because we matched your DNA swab to a piece of bloody fabric at the crime scene and that three of your fellow students claimed you threatened to kill the professor.
I didn't want him dead, okay?
You just wanted to torture him.
It's not like that at all.
He was going to kill me.
I mean, not really.
I'm so freaking confused!
One minute, I... hated him so much.
Now I see it was just all part of his lesson.
Part of his lesson?
You mean Hanging 101?
It was a mock lynching.
No!
Metzger was making some point about normal people following social norms.
You mean like the Stanford Experiments?
My friends turned on me in, like, two seconds.
Strip him.
( cloth ripping ) ( whimpering ) Get off!
That sounds degrading.
Did he treat other students badly?
His research papers won awards.
Ned, don't you think that a human being should have greater value than a research paper?
Hmm... this is not good.
Hello?
Excuse me.
Excuse me, but what are you doing here?
Miss, Miss...
You in the sweater.
What are you guys doing here?
He had an open-door policy.
Plus, we all had keys.
Why didn't you mention this before?
Our relationship with our professor is none of your business.
Okay.
You want to tell me more about this open-door policy?
Sometimes he needed help typing up a paper.
Sometimes we would take his laundry to the cleaners.
We were all really close.
Listen to this: "No man chooses evil because it is evil.
He only mistakes it for happiness."
Wollstonecraft.
Why anyone needs to prove that evil exists is beyond me.
Took us 600 years to classify slavery as evil.
Got a lot of paper here shredded for a pack rat.
Maybe he's got an awful lot of secrets.
You got the bolt cutters in the truck?
Nice.
Very nice.
Jade... honey, stop there and photograph.
( camera whirs ) Circular fracture of the cranial vault.
So his head hit something.
Or something hit his head.
Adhesive tape... something was here on the dash.
This car was stripped.
Not of its parts, but emptied out.
This guy was traveling light, too.
There's no wallet.
Maybe I can get an ID from the VIN number.
You think he drove his own car to his death?
No.
I think somebody cracked his skull to knock him unconscious, shoved him in the trunk and then chauffeured him to a watery grave.
A wad of paper...
$1.50 and a car key.
Oh.
This alters your theory, Delko.
Whoever drove him to his watery grave...
Handed him the keys first.
Something happened at that canal.
Neil Diamond CD. Love songs.
Oh, now we know why he was killed.
He was alive in there.
Eric Delko.
Yeah. Yeah, go ahead.
Okay. All right, thanks.
Autopsy concurs.
Cerebral anoxia and ventricular tachycardia.
Death by drowning.
I'm going to run the blood.
I'm all over your toolmarks.
62 wounds and not one nicked bone or cartilage for a nice toolmark.
An educated torturer.
I guess you're going to have to settle for the old wound comparison.
All right. Time to get medieval.
These tools don't match the wounds.
And worse than that, the blood on him was canine.
So what in the hell dug into the professor?
Lorenzo Castanotto?
Call me Larry.
You guys found my car?
Yeah, Larry we found your car at the bottom of Snapper Creek Canal.
You know how it got there?
Somebody stole it.
I already got paid by the insurance.
Did you give the thief your car key?
You found the car key?
Inside the pocket of the dead man stuffed in your trunk.
Hey, we haven't ID'd him yet, but maybe you could help us out.
Take a look.
Yeah, sure.
DELKO: Be warned, he's a... a little bloated.
Oh, my God.
What's the matter, Larry?
You don't recognize him?
Uh-uh.
Mind if I take this, Larry?
No, you can't take my hula girl.
That's all right.
We'll come back with a warrant.
Knock yourself out.
See you later, Larry.
SEVILLA: Who removes a hula girl from their car right before it's stolen?
The same guy that smacked our vic on the head before he stuffed him in the trunk.
That's right. Keep me posted.
All right. Be safe.
CAINE: Well, that looks like a match, doesn't it?
Metzger tortured this dog, didn't he?
And then someone tortured him.
CAINE: We need to figure out who this dog belongs to.
How?
Hang on a minute.
Oh, okay.
Okay...
Well, there you have it.
An identification microchip.
Lojack for dogs.
Mm.
Ginny Taylor.
Mm-hmm.
So now, her relationship with the professor officially becomes our business.
Good.
( crying ): Fisher ran away like three weeks ago.
I put up signs, you know.
I was just hoping that...
Oh, my God.
Do you have any idea how he got to the tree?
No, I can't think of...
Somebody tortured him.
Tortured?
That's right and weapons that we found in the professor's house matched to the dog's wounds.
What are you saying?
Professor Metzger... killed Fisher?
His artifacts were under lock and key.
So he was the only one who had access.
Ginny, the professor had a very serious interest in human cruelty, didn't he?
The professor was a genius, okay?
And he taught us...
About hatred. Right?
It's more than that.
The professor proved to us that violence is natural.
Without it humanity would become... unbalanced.
Ginny, was the professor hurting you?
He... he was...
He once asked me to kiss his shoes and I did.
Who killed him?
I don't know.
Dug through recent teletypes of local missing persons and I found one guy that fits bloater boy's general height and coloring.
Okay, and the mystery man is?
Doug Reid.
Now, he lived with a girlfriend who reported him missing after the car was stolen.
We're trying to locate family members but in the meantime, the girlfriend is...
Right on time.
That's the only picture I have left.
I ripped up most of the others.
You were living together, right?
Caroline, how long were you with him?
Really long... like three months and he was so romantic.
You know that song, "Sweet Caroline"?
By, um...
Neil Diamond.
Yeah.
He used to sing that to me all the time and we were going to go to Aruba...
but when he left I figured all my hints of vacations must have freaked him out.
What about enemies?
None.
As far as I know.
How's the autopsy photo I brought?
It's not looking so good for an I.D.
Wait a second.
Earplugs.
I wonder if they're custom.
Thank God for ears.
Pure cartilage.
Only thing on a bloater that holds its shape.
That's right.
( typing ) Hang on.
Reed Metal Works?
Reed Metal Works, that's Larry's place.
Larry?
Suffice it to say, Jade the world just got really small.
Hey, I've got my glass slipper.
Now where is my Cinderella?
Cremated yesterday.
No, come on, you didn't do that to me.
Yeah.
Please don't tell me you did that to me.
Hey.
I tested for epithelials on the rope, and no go but I did just identify the rope itself.
It's Guadua Augustifolia.
That's bamboo.
Bicolor variety, Colombian bamboo.
Okay, well, the dean did say the professor had interesting guest lecturers, didn't he?
One of whom was a Colombian prison interrogator which is just a really nice way of saying "torturer."
Torture can be interesting. Let's bring him in.
Tell me about your relationship with Metzger.
Señor Barbosa ¿cuando fue la primera vez que usted contacto al profesor?
¿Que tipo de relacion tenia con el profesor?
Usted es una muy buena estudiante, señorita.
She is not a student.
She's a police officer, so I suggest you answer her questions before you have to answer mine.
We're all the students...
in one relationship or another.
So you do speak English.
The professor-- did he suffer?
Was he left in a... humiliating position?
This is about power for someone like you.
A narcissistic fantasy in which you degrade somebody until they lose their identity and their soul.
Higher.
( gasps ) No.
Abuse is more than power.
It is... intimacy.
You'd be surprised at how attached prisoners can get to their jailers... their teachers.
So you see yourself as a teacher, is that it?
Teachers, parents, mentors.
It is how they start to view us.
That's true but most of us, señor arrive at that position through respect and not force.
An intelligent assessment, Lieutenant.
It is not what you do to people.
It's what you get them to do for you.
Through pain?
Mental skill, not weapons is your most important tool.
Yes, and it requires an enormous amount of mental ability to slice someone up and tie them in a tree.
I would agree.
I would... agree.
Take a look at those...
señor.
Are these an example of your skill?
I'm really sorry to disappoint you, Lieutenant.
How's that?
Yo soy inocente.
His flexor tendons are severed in his hand.
He couldn't even pick up a pencil.
Let alone string a man up in a tree.
A gift to the new regime from the old, I suppose courtesy of a machete.
Torture the torturer.
It makes sense.
So he's not our killer.
Hmm.
Oye.
How'd the hula girl match up?
Dead on.
And speaking of the dead?
Doug is indeed Doug.
Okay.
So what's that?
A piece of paper Megan found in bloater boy... Doug's pocket.
A travel brochure.
Yeah, for Aruba.
Doug wasn't gun-shy after all.
Mmm.
There's writing.
And directions.
"Take Bus 15 to F.R."
F.R.?
Flip it over.
I don't know if I can without ripping it.
I'll try. Let's see.
Well, hello, Larry.
Officers.
What can I do you for?
Well, you can start by answering a few more questions.
Yeah, we identified the body in your trunk and it turns out he used to work for Reed Metal Works, too.
We also found your name on a deposit slip inside the guy's pocket.
I don't know what you're talking about.
Insurance fraud gets two to six.
Murder's quite a bit more.
Okay, yes.
Doug and I were going to make some money on my car but I did not kill the guy, I swear to God.
You got an alibi?
Yeah.
I was at the dog track, Flagstone Ridge.
I even paid with a credit card, you can check it out.
That's handy.
I swear, Doug was my friend.
I would have no reason whatsoever to kill the guy.
Is that right?
Hey. Go home.
Get some rest.
I can't.
At this point I'm addicted.
What've you got?
"The experiments "with the dog exceeded my expectations.
"Standing under the tree taking notes I could feel my assistant breaking."
So maybe torturing the dog was designed to torture someone else.
I actually felt sorry for this guy.
All right, so they all did things for him but who was the assistant?
Maybe the person that shredded all these notes.
Or maybe whoever it was that typed them up in the first place.
Computer keyboard has at least 26 places.
Yes, for nervous hands to leave sweaty fingerprints.
Maybe there are more torture items than in the closet.
There's no prints on the keyboard.
Everything's wiped down.
Okay, folks, this is what I think happened.
I don't think the assistant was wiping down for prints.
I think the assistant was wiping down for blood.
And there is the six-inch ice pick.
There's no way that's more than five inches.
Metzger's body must've caved under the thrust of it.
Leading naturally to an overestimate on the weapon.
Hey, you might want to take a look at this.
Okay.
Maybe the retinal damage was caused by staring in the incandescent light for 100 copies.
Well, that would explain the Miami snow blindness, wouldn't it?
I found Metzger's eye opener.
That...
is a death mask.
Too bad the killer didn't leave a picture of himself.
Or herself.
Wait a minute.
Shine your light right there.
It's cotton.
Who wears cotton sweaters in 80 degrees?
Yes?
Hi, Teresa, I have a warrant for your taser.
Taser?
Look, there's, uh, two ways we can do this.
Thanks.
( electrical whizzing ) Clever.
Hey.
So... ( clears throat ) We got an accident reconstruction program.
Yeah, but the two people who look guilty have air-tight alibis-- And somehow, my vic got in his car and that car went in the river.
Okay.
Now, the center of gravity is forward because of the engine and the slope.
But when I run the coefficient of friction even with Doug in the trunk, the car doesn't move.
What was the condition of the ground that night?
I programmed it in as rocks and dirt.
Rocks and dirt.
Wet or dry?
I'll check the weather report.
Let's do that.
DELKO: There was a hard rain that night.
Love those computers but it's always better to see the crime in context.
So, I'll be Doug, okay?
So, my plan is to dump the car I take my buck-50, I hop on Bus 15 back to Kendell, return the key to Larry collect my money, and purchase a vacation for my girlfriend.
So, he tries to dump the car but ends up in the trunk instead.
Let's find out why.
Okay. Um...
the car's in neutral... and the emergency break is off.
Mud slippage changes the coefficient of friction from point seven to point three.
So you, Doug, get out of the car and is about to push it in.
When I go to the trunk to open it. Why?
Neil Diamond.
( chuckles ) Hmm?
You're right.
Hmm?
You're right.
I'm a hopeless romantic and I'm listening to "Sweet Caroline"
while I'm preparing to take a vacation with my own Caroline.
So...
you open the trunk but can't reach behind the CD changer.
Okay, so I climb in...
Mm-hmm.
Okay, so I climb in...
Mm-hmm.
and slip...
Wait a minute.
There's your blunt-force trauma right there.
Things we do for love.
CAINE: Metzger was a very demanding man, wasn't he, Teresa?
Everyone thought he was a genius.
They thought he was funny and inspiring.
But he wasn't on a mission to torture them, was he?
What do you mean?
I think you know.
Over the course of the last year he broke you down.
He took a happy, healthy young woman and turned her into a destructive creature, didn't he?
No.
No?
Take a look at your arms.
I respected him so much.
And that's what he depended on.
( dog yelping ) ( crying ) He started with a dog...
Who am I to correct a professor?
Teresa, we matched burn marks on the professor to your taser.
Why would I do that?
METZGER: This is what you call writing?!
You're a mental defective, do you understand me?!
You've got no brains at all!
You're a trust-fund-made bimbo!
Shut up!
( anguished cries ) ( screams ) Huh? Am I a moron?!
We have also matched his lacerations to the staple remover.
( panting ) So you walked him out to the woods filled with anger and adrenaline and strung him up in the tree.
Come on!
Take it off! Right now!
Okay!
I said strip!
Get down. Get down!
I would imagine that the worst part for you was finding out that you'd been an experiment all along.
Had I known that I was a test that he didn't mean all those things that he said I wouldn't have snapped.
But I'm glad he's dead.
After six hours of torture, I bet he is, too.
