Let's bring in "gma's" legal analyst, dan abrams. You've been following this case from the very start. Were you surprised by the verdict? Not really. A lot of people talk about this case. And say it's all based on hearsay evidence. That's true. One of the reasons we generally don't allow hearsay evidence in because it's so powerful. It's inflammatory. You're talking about witnesses coming forward and recounting conversations that drew peterson supposedly had with people. That's incredibly powerful evidence when you're talking about the notion that drew peterson allegedly confessed to stacy peterson, that kathleen savio was afraid of him. She slept with a knife under her bed. These are important and powerful statements. In the meantime, the prosecutors were not allowed to talk about the fact that drew peterson's fourth wife have also gone missing. Many people suspect she may be the victim of foul play at his hands. The prosecutors clearly believe that. And hay talked about the possibility of charging him. They may be able to use that in the sentencing phase. In front of the jury, they weren't allowed to bring that up. But in front of the judge, when talking about what kind of sentence drew peterson should get, they sure are going to be mentioning stacy peterson in the hope that he gets the maximum, 60 years. This case has gotten so much publicity. There was a made-for-tv movie. No question some of the jurors knew that. Made that clear during jury selection. Prosecutors with not permitted to enter deuce evidence about that during the case. A quick aside. There was one question that puzzled a lot of people. The jury came forward after at least nine hours of deliberation to ask the judge what does unanimous mean? What does that tell you? It seems there may be one small divide in the jury before they came back. There were two theorys of first-degree murder that could be used in this case. Quickly, after they asked that question, they cam back. And quickly, do you think they will charge him or try to press charges in the fourth wife's disappearance? They may. 60 years will be a long time if he gets that. Dan abrams, thank you so much.
