Black Bart's last stagecoach robbery 1883

After 8 years of robbing stage coaches – but never passengers – Charles E. Bolton drops an important clue as to his identity and is captured shortly thereafter. Black Bart never shot anyone, and had a habit of leaving short poems, all signed, Black Bart, the Po-8. He was sentenced to 6 years in San Quentin, but served just over four. In actuality, he stole only $18,000.
