ST. GEORGE, Utah -- Polygamous-sect leader Warren Jeffs will spend the rest of his life in prison, but new reports show that he might be trying to cut his life short.

According to recently unsealed court documents from a mental health expert, Jeffs may have tried to hang himself in jail earlier this year. The official reported Jeffs threw himself against a wall and banged his head against it.

Also, in some phone records that were also released, Jeffs said “he's the most wicked man on earth” and has “committed immoral acts.”

"When they see Warren Jeffs talking about some of those things in his own voice,” private investigator Sam Brower said, “when they see that -- perhaps they will see that they have been misled."

In September, Jeffs was found guilty of rape as an accomplice in the arranged marriage of a 14-year-old follower and her 19-year-old cousin. He is also facing charges in Arizona and in Utah federal court on unrelated charges.
