Also, how did the wife find him at 4 a.m.? Did she wake up and try to wake him in their bed? Was he in another room and when she found him? Fox is now reporting on other stories...guess they are waiting for details.
How did he die? Gunshot? If so, when and where did he buy a gun?
Did he hang himself? That is an even more horrible thing for his wife to find, and again makes it odd for him to kill himself at home.
There are no people saying he was depressed. Seems to have been a rather sudden reversal of mood.
