Not necessarily. I don't think LE approached this the right way either. I've said this a number of times. Missed opportunity when they went to serve that warrent for the car and the phone and the apartment. You don't get cooperation when you wake someone in the wee hours of the AM and serve those warrents. They were more interested in the item than with him or his roommates as they slipped away unnoticed. They really should have had a trained interviewer there. But then, who knows maybe they did try before that and haven't said anything to the public. But if they did not, that was a mistake. It really should have been more crucial to get him under watch, and try to get him to talk about Hannah than it was. They just let him slip away right there.
He shouldn't say anything at this point, innocent or guilty. All statements should come through his attorney.
Though cases have been won without a body, such as the recent Alexis Murphy one, it's more diffiicult. The perp, Randy Taylor talked too much, caught lying about so much. If JM just stays mum, DA is going to have to prove every bit of the case beyond reasonable doubt.
Longo has to appear confident with all the time, money and resources spent. If he has nothing, he'd be in big trouble. LE has to look like they are doing something. I'm really not that impressed with the way it was handled, though perhaps a lot was not released. No idea where Hannah is still. All that trouble to have to get the perp in custody. All ths time. I'd be so upset if I were a parent.
