Answer:
At his trial, Ed Gein was found mentally unfit and committed to a state mental hospital. Gein's mother was a religious fanatic and was incredibly strick and harsh. Gein's father was not much better. Gein had one brother and they lived on the same plot of land for many years. His family members died off one by one until he eventually lived in the old farm house by himself. The solitude probably didn't help an already sick mind.
