William Hamilton Gregory, 30, of Honey Brook, Pennsylvania, disappeared December 30, 2003. He was described as a white male, brown hair, green eyes, about 5 feet 9 inches to 5 feet 10 inches and 140 pounds, with distinctive tattoos: a sunburst on his neck, the words Shadow and Squirrel across his shoulder blades, and a Tasmanian Devil with a Rebel Flag on his biceps. When last seen he wore a black mechanic’s jacket, a grey sweatshirt, black jeans and grey and blue sneakers.

His 1987 red GMC pickup truck was recovered December 31, 2003. Pennsylvania State Police information points to a violent altercation and indicates investigators believe William was dumped into the Conestoga River at or near the Safe Harbor Dam where the Conestoga meets the Susquehanna. His body has never been recovered and officials have described him as the victim of a homicide.

Anyone with information about William, his truck, movements around December 30–31, 2003, or knowledge of the Safe Harbor area around that time is asked to come forward.
