Joseph J. Lynch

Detective Joseph Lynch and Detective Ferdinand Socha were killed when a time bomb they were inspecting exploded.

Detective Socha and Lynch were called to the World's Fair Grounds and directed to the British Pavilion after an electrician found a suspicious satchel in a fan room. The canvas bag was emitting a ticking sound, so it was carefully carried to the rear of a secluded area near the Van Wyck Expressway, where it was placed beneath a 20-foot maple tree. Detective Lynch took out a pocketknife and slit open a 2-inch hole in the bag as his partner knelt down to look inside. As the Detectives were examining what appeared to be dynamite, the bad exploded. The explosion opened a crater 5 feet wide and 3 feet deep and killed both Detectives. FOur other Police Officers were critically injured.

It was never determined who planted the bomb, or what motivated the bombing.

Detective Lynch was assigned to the Bomb Squad.
