Sergeant Ralph M. Galdi, 45, was a 21-year veteran of the Philadelphia Police Department’s Sex Crimes Unit. On March 31, 1986, while returning from court, he and his partner witnessed a vehicle run a red light and collide with another car. The driver of the offending vehicle attempted to flee, prompting a foot pursuit. At the intersection of North 5th Street and Spring Garden Avenue, the suspect, identified as Pedro Vega, produced a .38 caliber revolver and opened fire. Galdi was struck three times and died of his injuries.

Pedro Vega was arrested and charged with first-degree murder; a jury later convicted him and imposed life imprisonment plus 45 years after deciding against the death penalty. Galdi was survived by his wife, two daughters, and two sons. His colleagues remember him for his dedication to the department and the community.
