The one thing I give Nick credit for is he hasn't run to the media to blab like a lot of people. I know he's made some public tweets but that's been it besides a few statements from his lawyer.
If LE has not already interviewed him, I'm really confused. I assumed they would have done that on day one. If he hasn't been, he needs to talk to them. I keep going back to that report about BK's face and Nick's hands supposedly having injuries. If that were true, Roswell PD would have to be completely incompetent to have not talked to him.
If the family has evidence he may have hurt BK then by all means keep him away but if not, I hope they can work something out so he can see her. I don't believe in any miracles at this point but he should have a chance to say good bye.
