Deputy Sheriff Langford A. Hennessey

Langford A. Hennessey

Deputy Sheriff Langford Hennessey, Sheriff Wash Coppinger, and Deputy Sheriff James Conner were shot and killed in a shootout with members of the South Pittsburgh Police Department who held a grudge against the sheriff.

The city's night marshal was the former sheriff and had lost his re-election bid against Sheriff Coppinger. The night marshal had appointed a man who had been arrested by Sheriff Coppinger as a deputy marshal.

During a labor strike at a local factory, the night marshal and his officers supported the non-union workers who were being harassed by striking workers because they were not participating in the strike.

A county deputy witnessed the officers holding a union member at gunpoint and approached them. The city officers then held the deputy at gunpoint before dispersing. The deputy immediately notified Sheriff Coppinger, who responded to the scene with Deputy Hennessey, Deputy Conner, and his son, who was also a deputy.

The sheriff and deputies confronted the officers on 3rd Street, near Cedar Avenue, and attempted to resolve the situation peacefully by offering to discuss it with the mayor. The sheriff then informed one of the officers he would have to be arrested for pointing the gun at the deputy.

One of the officers then opened fire with a shotgun. During the ensuing shootout, Sheriff Coppinger and Deputy Hennessey were killed, along with the city's night marshal, his deputy, and a special officer who worked at the local factory. Deputy Conner, who also served as the South Pittsburgh police chief, suffered a fatal shotgun blast and died the following day.
