Sam Parker

With no body, no crime scene, and no murder weapon, prosecutor Lee Patterson has an uphill battle.

You wish that you had everything, but that's not how a case works.

And we felt like, even though we didn't have a lot of forensics, that we had a lot of other stuff that was really good.

Defense attorney David Dunn.

How unique is this in that there's no body?

The prosecution admits they don't know exactly how Teresa died, but they're convinced the circumstantial evidence against Parker proves he's a murderer.

Teresa's niece, Ashton Gilbert.

Parker's second wife, Keila Beard.

The prosecution lays out its theory.

Teresa left her new apartment shortly after midnight, driving to the home she shared with Parker.

She didn't think he'd be there, but he was waiting for her.

Sometime between 12.30 and 1.30 a.m.

on March 22nd, 2007, he killed her.

After he killed her, he put her body in the back of the SUV, and then he went to Christy Bellflower's house.

Incredibly, prosecutors say, Sam Parker was heading out on a date.

All right.

Well, tell me, what kind of container did he have it in?

On water bottle.

Okay, so an hour to kill her.

And then you say he left her body in her SUV.
