I'm sure LE NEED to know why DM refuses to talk to them or tell them anything about what happened that night and who the other people are. If DM is innocent, he sure isn't doing himself any favours in getting his name cleared and getting himself out of this mess. He's just sitting in jail silent, waiting for LE disclosure on what they know, while allowing LE to get search warrants on all his properties and vehicles. And he's just sitting there allowing all this speculation regarding the death of his father and this missing woman to be cast upon him.
If DM is innocent and can prove it, there is no need for him to be sitting in jail right now. He should be working with LE to help find the person's responsible for TB's death and for "planting" all the evidence all over his property. If it were me and I had nothing to do with it, I'd be outraged and giving LE the names of every single person I knew who might have access to my stuff. I'd be cooperating and working with them. Not sitting in jail hoping they don't find anything incriminating against me.
MOO
