He hanged himself... not terribly peaceful. He was a very troubled and depressed person but no one really did anything about it. We don't know all the details but I would say there were warning signs people ignored.
That is correct we don't know the circumstances leading up to death, Please don't assume no one did not do any thing about it or there were warning signs people ignored.
I had a brother who committed suicide many years ago, no one was any the wiser of his intentions & this is something I my family & friends have to live with for the rest of our lives as there were no signs of him seeking attention or help or displaying signs of trouble.
People can be very clever hiding their true feelings/problems.
