Michael J. Lebedda, an officer with the Munhall Borough Police Department, was shot and killed on November 17, 1917, while attempting to arrest Jack Thompson and two other men after they had robbed a man in Duquesne. The three assailants fled.
Thompson was arrested in North Carolina in May 1919. At trial, he was convicted of first-degree murder and sentenced to death in December 1919.
Before he could be executed, Thompson died of tuberculosis in the Allegheny County Jail on April 7, 1920.
