The Most Dangerous Female Criminals of All Time

Kate 'Ma' Barker

26. Kate ‘Ma’ Barker

Kate Barker, widely known as ‘Ma’ Barker, controlled and fronted the Barker gang in the 1930s, which consisted of her and her sons. Together, they conspired and executed a large number of murders, kidnappings, and robberies all through the United States.  

But in 1935, the FBI finally caught up with Ma Barker and her sons. In perhaps the longest shootout in FBI history, they were eventually shot and killed.
