For 16 years New York City was under attack by a serial bomber. In the 1940s and 50s The Mad Bomber placed dozens of bombs around New York City in theatres, businesses, train stations, and libraries. The bombs left an entire city on edge for years as the police desperately searched for their creator.
Thanks to some smart thinking by investigators the Mad Bomber case used one of the very first criminal psychological profiles created by a psychiatrist and opened the door for a whole new investigation technique.
