What happened to Black Bart?

Black Bart, the infamous stagecoach robber, was active in California during the late 1800s. After a series of successful robberies, he was captured in 1883 due to a distinctive handkerchief he left at the scene of one of his crimes. He was sentenced to six years in prison but was released after serving only four years for good behavior. Following his release, he reportedly retired from a life of crime and disappeared from public view.
