Dillinger, Dock Barker, Van Meter, and Davis later buried Hamilton in an unmarked grave. Davis and Murray were never charged with the holdups he committed while part of the Karpis-Barker Gang. However, they were indicted for the Bremer kidnapping on January 22, 1935. A little over two weeks later, Davis was captured in St. Louis by federal agents on February 6 but escaped from federal custody the next day. He had been traveling under escort to stand trial in St. Paul when their plane was forced to land in Yorkville, Illinois. Once on the ground, Davis knocked out a guard and stole a car. He evaded capture for nearly four months before being traced to Chicago by the FBI and arrested by Agent Melvin Purvis on June 1. He was eventually returned to St. Paul where he was convicted of kidnapping and sentenced to life imprisonment. Davis cooperated with the government and gave information as well as testified against other members of the gang. Like the rest of the Karpis-Barker Gang, Davis was sent to Alcatraz, where he spent the next several decades. He did not participate in the escape attempt organized by Arthur Barker in 1939. There are claims that he became involved in a violent fistfight with Karpis, which he won. By the time of his release in the late 1950s, however, he was in poor health. Davis married Daisy Irene Graham on May 21, 1960, in Contra Costa County, California, and resided in Guerneville, California. He died on July 20, 1979, in Sonoma County, California.
