To me, it's very telling what the family has been saying. In their interviews they allude to there being personal and professional problems. What they are saying publically to me seems like they think he took a break, that he needed to get away from the stresses and pressures of his life. They seem to be fine tuned into his every day life. They sounded the alarm almost immediately once they couldn't get ahold of him.
What I'm trying to say is that they know why he would disappear. What they don't seem to know is if he did disappear on his own. I'm also getting the vibe they think he could be suicidal, without trying to say he is. They don't want to put that kind of information out there because of his career and stature.
But in reality, at this point, he has been missing a month. Without any of his possessions, car, money, credit cards, phone, nothing to survive on.
I think he had a mental break. And I think his family knows it and are scared to death, as well they should be. I don't know, maybe he's in a homeless camp, and loving the peace and uncomplicated life it affords.
It's just that to me, the family and what they are saying and how they are acting is a good indicator of what they fear has happened to Tim. JMO
