The whole situation was very sad and I feel for his family and friends...suicide is not the way to go.
How do you determine that "loads of weapons" from five guns? It's a hunting community/area. I know lots of hunters that have various sorts of guns for hunting and recreation. People love to go out and target shoot around that area as well.
I'm not sure if he was arrested yet. They were too busy trying to SAVE HIS LIFE!
