Actually a range me and my brother frequented had a suicider who also took hostages. Luckily no one but the individual got harmed.

I also know one of my local walmarts had a man shoot himself with a shotgun in the head in the parking lot. When something like that comes up it really does bring a lot of questions, but it also makes you thankful. Why the Walmart parking lot? I can only think there was a thought to do harm to others. My father's a funeral director and the wake that suicide causes a family is so intense, it is a much different atmosphere at a suicides funeral compared to any other. I will say that the most intense is of course victims of homicide, often times it's women from domestic abuse gone wrong, very sad circumstances that can't be disputed as anything less.
