Jeff Erickson -- 1992
A Hanover Park couple, Jill and Jeff Erickson, robbed a string of Chicago-area banks. When they were caught in 1991, she was mortally wounded in a chase with FBI officers, and he was arrested and taken to the Metropolitan Correctional Center. But as he was being led from the Dirksen U.S. Courthouse on July 20, 1992, Erickson uncuffed his hands with a handcuff key, disarmed a guard and fatally shot Deputy U.S. Marshal Roy "Bill" Frakes and court security officer Harry Belluomini, a retired Chicago police officer. Erickson, mortally wounded in an exchange of gunfire with Belluomini, shot himself in the head a few feet from a rush-hour Loop crowd.
