John David Watson was 14 when he left his Dunbar Township, Pennsylvania home on the evening of May 2, 1974 to buy cigarettes for his mother and never returned. Watson, who was white, was found the next morning on a neighbor’s property with a gunshot wound to the back of his head.

Decades later new forensic testing in 2009 on a coat belonging to Joseph Leos, a childhood friend, detected gunpowder residue. Leos, who was 17 in 1974, was arrested and charged with homicide in 2015, but those charges were later dismissed because the evidence was deemed inconclusive. The investigation remains open and the Pennsylvania State Police have offered a $5,000 reward for information. Watson’s family has described their ongoing heartbreak over the lack of closure.

Are there any neighbors, classmates, or others from Dunbar Township in 1974 who can add details about John’s last evening or about people seen near the motel that night?
