Alvin Karpis
Alvin Karpis was a member of the notorious "Ma Barker Gang," also known as the "Barker-Karpis Gang," which terrorized the Midwest in the early and mid-1930s with bank robberies, kidnappings, and murders. Karpis was arrested by J. Edgar Hoover himself. Karpis served 26 years on Alcatraz -- more than any other inmate.
