Bill Hickman was an early follower of and bodyguard for Mormon founder Joseph Smith in 1839. After the move to Utah, Hickman became a sheriff, prosecuting attorney, assessor, territorial legislator and successful businessman.
But Hickman later wrote that he had a dark side—as an assassin for Brigham Young, killing dozens of Mormon opponents and apostates. Young denied the charges and excommunicated Hickman.
He lived the rest of his life as a pariah, shunned by Mormons and feared by non-LDS folks. Bill Hickman died in a Wyoming sod dugout in 1883.
