Sam Parker

He had even given her money for shopping.

But there was something about her trip that troubled him, so he decided to do a little investigating on his own.

Parker called the lodge and convinced the clerk to send him Teresa's registration, defense attorney David Dunn.

Prosecutor Lee Patterson.

He was very angry about the Gatlinburg trip because he was convinced that she had cheated on him.

Parker's suspicions about Teresa and another man grew when he found something else puzzling on her room reservation.

Remember, Shane Green was the police officer who discovered Teresa's SUV missing the morning the prosecution believes she was murdered.

You don't think that this could have just been a work relationship?

The defense says that there were two people staying at that lodge, that Teresa had somebody with her.

No?

No, there were not.

Our information is there was nobody there to see her.

And if the defense wants to say that Shane Green was there with her, the cell phone towers show that his cell phone activity was not in Gatlinburg.

Green says he was not in Gatlinburg and was never romantically involved with Teresa.

So all of this jealousy that Sam seems to have

is unfounded?

In my opinion, yes.

He was a very controlling, manipulative person.

And I think that Teresa was tired of being controlled and manipulated.

According to prosecutors, Teresa Parker did have one big secret.
