Known as The Confession Killer, he claimed to have murdered more than 600 people.
He was accidentally stabbed in the eye at age 10, and had a glass eye the rest of his life.
He recanted many of his confessions, and many others are thought to be false, yet he is still considered one of history's most prolific serial killers.
He married a widow in 1975 but they divorced when she suspected him of molesting her daughters.
He at one time claimed to have contributed to the body count of The Green River Killer, Gary Ridgway.
