Geronimo was the scene of one of the deadliest bank robberies in recent Oklahoma history on December 14, 1984. Shortly after 1 p.m., Jay Wesley Neill entered the First Bank of Chattanooga in Geronimo, and forced the three tellers to the back room, where he had them lie face down on the floor and stabbed them to death. The three employees (Kay Bruno, 42; Jerri Bowles, 19; Joyce Mullenix, 25) were stabbed a total of 75 times. Mullenix was six months pregnant.
