Summary based on the NamUs case record (MP27414)
William Hamilton Gregory, a 30-year-old man from Honey Brook, Pennsylvania, vanished on December 30, 2003. At the time of his disappearance, he was described as a white male with brown hair and green eyes, standing between 5'9' and 5'10' and weighing around 140 pounds. He had several distinctive tattoos, including 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 was wearing a black mechanic's jacket, a grey sweatshirt, black jeans, and grey and blue sneakers. The circumstances surrounding his disappearance are deeply troubling, with reports indicating a violent end to his life.

The investigation into William's disappearance took a dark turn when his 1987 red GMC pickup truck was recovered on December 31, 2003. Information gathered by the Pennsylvania State Police suggests a grim scenario. It is believed that William was involved in an altercation and was subsequently dumped into the Conestoga River. This event is thought to have occurred at the Safe Harbor Dam, near the confluence with the Susquehanna River in Lancaster County. Despite this information, his body has never been recovered.

The case of William Gregory remains a somber mystery. Law enforcement officials received information that he was the victim of a homicide, with his life tragically cut short and his body disposed of in the river. The lack of a recovery has left his family without the closure of a proper burial and has complicated the legal proceedings that might bring those responsible to justice. The overview of the case points to a violent crime, with the Conestoga River holding the secrets of his final moments. Despite the passage of time, the investigation continues in the hope of one day finding William and providing answers to his loved ones.
