Black Bart (Charles E. Boles) wore socks over his boots during his robberies so that he couldn't be tracked. He considered himself a gentleman outlaw and enjoyed taunting his victims by leaving little bits of poetry behind in empty strongboxes to confuse those that would pursue him. He was eventually arrested in 1883 after dropping a handkerchief with an identifying laundrymark at the sight of one of his stagecoach robberies. He was sentenced to San Quentin Prison for six years, but had his sentence shortened to four years for good behavior. A short time after his release, he disappeared and was never heard from again.
