I personally knew 2. They were both young men who had appeared very holy and had a lot of family expectation upon them.
One of them, the last time I saw him, had three day old dried blood all down the front of his shirt and ants crawling in every orifice in his head. He shot himself in the mouth with a 22 rifle. Apparently, it being a small calibre gun the bullet skimmed around the inside of his skull 3 times before coming to rest. The word was that he didnt die immediately, not a nice thought.
The other was a fine friend of mine. He didnt mess around and used a double barrelled shotgun, sticking it under his chin. He drove into the woods, turned the stereo up full blast, and then pulled the triggers.
He was splattered all over the car.
