I'm not going to say how I know, but he's been in a lot of legal trouble and may be in jail. I think a lot of it has to do with alcohol, and he looks extremely rough for the wear. It's a shame because he's still pretty young (not quite 30).
I hope he gets his stuff together.
One guy who did a few scenes with him is dead now (Chris Taylor).
It's just kind of tragic how things turn out with these guys. You feel horrible for them when maybe they were dealing with something they didn't ask for, and even also feel terrible for their families too having to deal with the heartbreak.
