On This Date in Minnesota History: April 25

April 25, 1932 – In Feb. 1932, the Barker-Karpis Gang rented a home on South Robert Street in St. Paul. Their landlord Nick Hannegraf eventually recognized his boarders after seeing them in an issue of “True Detective Mysteries” on this date. “Eager to earn the $100 reward, [Hannegraf] alerted police to the location of the Public Enemies.”

At that time, the police were operating under the “O’Connor Agreement,” where St. Paul Police Chief John O’Connor’s policy was “outlaws were welcome as long as they checked in with police, paid a small bribe and promised not to kill, kidnap or rob within city limits.”  

When contacted by Hannegraf, the police tipped off the Barkers “who fled, leaving dinner on the table and a stolen $500 bond under the rug.”
