Nicholas Singleton (590)

4/30/2001: Singleton and a friend were smoking marijuana and driving a stolen call when caught by police. Bailing out of their stolen Jeep, the unarmed Singleton was chased by three officers up to a building rooftop. Each of the officers mistook the muzzle flashes of the other for Singleton shooting. After 19 shots he was fatally struck in the dead. An Internal Affairs investigation stretched on for more than a year; the city settled a wrongful-death suit with the family for $500K.
