Jonathan Edward Hagans was 3 years old when he disappeared from Jacksonville Beach, Florida, on June 11, 1968, during a family outing. Known as Jon Jon, he was last seen following his father toward a snack bar; witnesses said he reached for the door but never went inside. Extensive local searches, including lifeguards and the Navy, failed to find him.

Early police theories suggested he might have wandered into the ocean and drowned, but no body was recovered and Jonathan’s family suspected abduction after recalling a man and a woman near the snack bar that day. Decades later a man falsely claimed to be Jonathan; DNA testing showed he was not. The case has been periodically reopened, age-progressed images released, and the family has looked to advances in DNA for answers.

Does anyone have memories of Jacksonville Beach in June 1968 or information about people who were seen near the snack bar that day?
