On the night of June 22, 1976, 20-year-old Richard Williams, an active duty US Navy sailor stationed in Bremerton, Washington, was shot in Irving Park in Portland, Oregon. He was in town with his wife and friends, and the group had been playing on the park swings just after 1:30 a.m. when an unidentified shooter opened fire from a distance.

Williams was hit, ran with the others toward their car, and collapsed when they reached the vehicle. He was taken to a nearby hospital but died from his wound. Investigators recovered empty shell casings near the restrooms by the swings, but no suspect has been identified and no arrests have been made. A cash reward has been offered for tips leading to an arrest.

Anyone who was in or near Irving Park that night, or who has information about the shooting or the people involved, is asked to come forward.
