Happened at Arizona Range. I pulled up to shoot about 10 minutes after it happened. Police were in parking lot and just started to tape off area.
As I heard from witnesses who were inside the range at the time:
Man came in and seemed really nervous. Was asking a lot of question about guns and rented a few of them. Went to his lane and shot a few down range. He was asking for help with them and some of the witnesses helped him.. One told me that everybody thought there was something wrong with this guy. Just jittery and sweating. After putting a few down range with a .357 magnum he put the gun under his chin and pulled the trigger. He left a several page note in his car out front which the investigators retrieved.
