Public Enemy Number One the Barker~ Karpis Gang part Two

The Barker–Karpis Gang was one of the longest-lived criminal gangs during the Depression Era, spanning from 1931 to 1935. The gang was founded by Fred Barker and Alvin Karpis, and later joined by Fred's brother Arthur "Doc" Barker. Along with the three core members, the gang's network spanned up to 25 members at one point.

Although not as well-known as their contemporaries the Dillinger Gang, or the Barrow Gang, the Barker–Karpis Gang was perhaps more ruthless, not only committing bank robberies, but also extending the activities into kidnapping. It is best known for the myth that it was run by the Barker brothers' mother, Kate, usually referred to as "Ma Barker".
