I did once. About 7 years ago, my next door neighbor's wife and 4 young kids went to visit her parents. I saw him around 8:30PM in the driveway, coming home from work and we talked for a little while. Around 9:00PM, I heard I gun shot from his backyard. I looked out our sunroom window and saw him lying on the grass with blood pouring out of his head and a gun lying next to his hand. I called 911.
