Not sure about others, but the article didn't sit well with me. He laughed about other victims -- why couldn't he just say NO if he was anxious to tell about the other. I believe, and IMHO, that he gave up Amber and Chelsea, but there are others out there. As enraged as this dude is, I can't see him feeling so guilty about one, then killing another. I'm just not buyin it. Again, only my opinion from what I read.
If he's as guilty as he says he is, in time he may confess to others. As far as the plea deal - I tend to believe the DA and that it was offered up. I'm glad it was though, make him play with the big boys and not be another Scott Peterson. Though with his height and weight, he may be difficult to manipulate in there. Do I think he'll behave -- probably not. As hard as it is to say, I hope he goes the way of Jeffrey Dahmer.
