A friend of mine committed suicide at work using a gun. My office was two down from hers. She did it at lunch time so there was only myself and one other person on the floor at the time. We heard the bang, which surprisingly wasn't as loud as you would expect. When we went to see what happened it was quite a shock. There was a pool of blood on the floor and parts of her on the wall. Believe me, for anyone considering using a gun to exit, it is a trauma to anyone who finds you.
