Mr. Potter, your wife's body's been removed.

I'm really sorry.

Threats? By who?

People say things.
What did your wife do at Dade University?
Nothing. She was a stay-at-home mom.
We found these.
They're all for $120, all from this month.
These are paychecks made out to my wife's maiden name, Janice Garber.
Why is that? I don't know.
Let's find out.
DELKO: H, I heard about the shooting.
CAINE: Yes, they used \h an automated rifle, no prints, no trace, \h not registered.
Sounds personal.
Yes. We received a message before the shooting.
DELKO: A message? \h What, through the mail?
CAINE: They slipped it into \h the morning mail, exactly.
Why would they target us?
I think I just heard an "us" in there.
Yeah, that's right.
While I was gone, I realized this is where I want to be.
Then I have you full-time.
I'm back, if you'll have me.
That's good news.
First order of business.
These checks are from Dade University.
Let's figure out who this soccer mom really worked for, okay?
Good to have you back.
WOMAN: Janice Potter volunteered for a PhD psych research project I was conducting.
The university checks were compensation.
Did she mention needing to hide this from her husband?
Not that I can remember. Why?
Because she used her maiden name to get paid.
Everybody's got reasons for what they do.
What kind of research was this?
I was studying the moral compass of the human brain.
Kind of a new take on the Milgram experiment \h on obedience-- the one that explains Nazi Germany happened because of obedience to authority figures.
DELKO: It's a very controversial study, isn't it?
Yes.
So you got people like Janice who were lining up \h to be your guinea pigs?
WOMAN: She thinks she's shocking \h people, but I'm studying her.
All right, you will ask the subject a series of questions, and if the subject answers incorrectly, you will administer an electric shock.
Can you do that?
Yes, I can.
Great. Let's begin.
(buzzing) (yelling) My theory is \h that Nazi Germany didn't happen because people respond \h to authority.
Simply put, \h the brain wants to be evil.
Did she prove your theory right, she shock the subject?
Let's just say I'm glad we weren't using actual voltage.
(buzzing) (grunting, panting) But I have her to thank for my success.
I'm moving on to a better institution because of it.
Thank you for your time.
Good luck. CAINE: Yeah.

Well, this shooter didn't need to be a trained marksman to gun down a mother in front of her three-year-old.
He was a coward, and he just used a computer to do it. Well, can the computer at least help us track him down? That's what I'm hoping.

Is there a serial killer on the loose in Miami?
Is it true that police were warned about both of today's murders before they happened? Hasn't been determined yet.
Please do your job responsibly, so I can do mine. Lieutenant Caine, is there a serial killer on the loose in Miami? Have a great day.

Lieutenant, I didn't want to scare the others, but, uh...
I think Melissa Walls killed Janice Potter and Dr. Brusatti.
CAINE: Dr. Madsen, why do you think she did it?
About a week ago, Janice came to my office and accused Melissa of scientific misconduct.
Misconduct?
She caught Melissa doctoring the results of her study.

Ugh, I can't do this anymore.

See, I reviewed Melissa's findings.
She did doctor her studies.
She manipulated the data \h to fit her theory.
So we had no choice but to kick her out of the program.
MELISSA: I have her to thank for my success.
I'm moving on to a better institution because of it.
You cheated, Melissa.
No, you fired me.
What sort of message would we be sending the other students if there were no consequences to your actions?
MELISSA: I can't believe this.
You're just gonna ruin my career?
We'll speak on your behalf.
None of this will have to come to light.
Other institutions will have you.
Am I just gonna pluck another thesis out of thin air?
New question, new data?

Yes, well, from what I understand, you didn't achieve distinction, and that you cheated.
What, like no one ever cheats in academia?
One-third of researchers admit to cooking data.
All the greats did it.
Ptolemy, Isaac Newton, Washington Carver.
Did you or did you not kill Janice Potter and Dr. Brusatti? Is that your theory?
It is my theory.
You have no hard evidence.
Maybe I should accuse you of cheating.
Okay, why don't you come in and do it in person?
No. You're so certain, come and find me.
I will.

Of course.
Thank you. I'm just an adjunct professor.
I'm not tenured like Stephen and Neal.
I didn't have any power to sway the committee, and Melissa knows that.
Both of you were on her PhD committee, so what we're afraid of is that one of you could be next.

I didn't want to see her getting kicked out of the program.
That was their idea. It was a unanimous decision, Bob.

Hey, so when you guys found the fleur-de-lis, the spray paint-- it was tacky, right?
Yeah, tacky and non-transferable.
Right. Okay.
Well, I brought out the same acrylic aerosol paint, the same polyethylene sheeting, to recreate the exact same conditions.
See how long it takes for the paint to become tacky.
Exactly. Taking into account the difference in sun position, we should be able to approximate when our killer painted the fleur-de-lis.
All right, hit it.
Hit it.
Tacky with no transfer.
46 minutes, and we found the symbol at 2:15.
Okay. 46.
Which means our killer painted the fleur-de-lis at approximately 1:30.
Yeah, well...

That's good work, man.
Yeah, you put a lot into this day planner.

Apparently, you forgot where you were between 1:00 and 2:00 today.
I had a pilates class at this time.
We're gonna need confirmation on that.

The names of nine people from class. They'll be more than happy to set you straight.
I also have an affidavit from the instructor which states that I attended class from beginning to end, in case you doubt me.
Why didn't we get this before? You believed I was guilty.
I simply allowed that belief to continue.
DELKO: You wanted us to believe that you were guilty? No.
I was completely neutral.
You had a single theory. All your perceptions in this case were shaped to support that theory.
Why would you allow this to happen?
It's part of my new thesis.
First impressions, false perceptions.
Because of it, I just got accepted to Eastern Florida University.
The mind of an investigator needs an answer, so it seizes on a suspect, then alters perceptions so that all evidence fits that single idea.

We followed actual evidence.
