Chapman and Anderson were both sentenced to 25 years' imprisonment and ordered to serve their time at the Atlanta Federal Prison. Chapman escaped from the prison on March 27, 1923, knocking out the facility's power in the process. He was wounded and captured a couple of days later in eastern Georgia, but within a week escaped the hospital, adding to his national notoriety. Anderson broke out of the Atlanta prison on December 30, 1923. The two men reunited, and were suspected by authorities in several hold-ups.
