Sam Parker

That's right.

At their home and went on a date?

He had to have an alibi, and Christy Bellflower had expected him to come over there.

How's he gonna explain, well, I had a date, but I broke it?

After the date with Christy Bellflower early Thursday morning, prosecutors believe Parker drove home.

Then, sometime between 5.30 and 7.30 a.m., he drove off in Teresa's SUV with her dead body inside and dumped her.

That's our theory of the case because that fits with the timeline.

He goes back because he has to dispose of her body.

He can't leave her lying in the carport.

Defense attorneys Doug Woodruff and David Dunn said that scenario is ludicrous.

What do you make of the blood that was found on the rear bumper of Teresa's car?

But then prosecutors would call their most controversial witness.

Police officer Ben Chafin.

Were you and Sam friends?

Had you ever seen Sam and Teresa have a fight?

Chafin would tell the jury the most explosive evidence of the trial, a phone call from Sam Parker the night Teresa disappeared.

Chafin told the jury after that confession, he hung up the phone.

But a few minutes later, Parker called him back.

He said, if I told anybody, he'd have to kill me too.

Devastating testimony?
