In a Fox News exclusive, sources close to the case said that during a taped phone call between Peterson and Frey, Frey asked her former lover whether he'd had anything to do with his wife Laci Peterson's disappearance.
Responded Peterson, according to the sources: "Yes uh uh but no. But I know who did and I'll tell you later when I see you."
"Yes - uh - uh - but no." LOL. A confession like that really belongs in this case!
You're right, if he testifies, he's gonna need to explain it and he's bound to at least look a bit uncomfortable when he does. Of course, the defense will object to its admission, but it'll probably come in. ;-)
