His wife released a statement saying he was taking the anti anxiety drug Ativan. And when she talked to him after the show his voice was slurred and he mentioned maybe taking more than he should have. One of Ativans side affects is suicidal thoughts. Which may have caused him to make a decision that he normally never would have. If you are his wife and children you have to believe he would never choose that option if he were in his right mind. Really sad.
