Bernard Arthur Munn, a 40-year-old husband and father from Massapequa, New York, vanished on April 18, 1967. He was last seen driving westbound on Jericho Turnpike at about 4:00 p.m. after leaving the Volkswagen dealership he co-owned in Woodbury. Earlier that day he made a bank deposit of about $8,600. His dark blue 1967 Volkswagen Fastback, New York plate SA9713, was with him and was never recovered.

Bernard is described as a white male between 5 feet 8 inches and 6 feet 2 inches, weighing 190–200 pounds, with brown partially balding hair and hazel eyes. Distinguishing marks include a V-shaped scar on his left wrist and a five-inch scar on his right shoulder. On the day he disappeared he wore a plaid jacket, grey pants, brown shoes, black horn-rimmed glasses, a gold watch and his wedding band; he carried a V money clip.

Despite searches and public appeals by the Nassau County Police Department, no trace of Bernard or his vehicle was ever found. Theories mentioned over time include accidental drowning, foul play, or voluntary disappearance, but there is no evidence supporting any single explanation. Anyone with information about Bernard, his car, or his movements on April 18, 1967 is asked to come forward.
