Summary based on the NamUs case record (MP9151) and 10 other sources
On a Tuesday in the late summer of 1981, a 30-year-old man named Ryan Jan Kemp was seen for the last time. It was September 15th when Ryan, a resident of Germansville, Pennsylvania, was spotted having lunch at the King's IGA Supermarket in North Whitehall Township. After that sighting, he seemingly vanished, leaving behind a life and a future that was just beginning to take a new direction. Ryan, a 1969 graduate of Slatington High School where he had been a good student and athlete, was remembered as a bright individual. He had attended Pennsylvania State University for a couple of years and later worked for the New Jersey Zinc Co. before being laid off. At the time of his disappearance, he was enrolled as a part-time student at Lehigh County Community College, with aspirations of a career in mechanical engineering.

The days immediately following Ryan's disappearance only deepened the mystery. Two days after he was last seen, his truck was discovered abandoned in the parking lot of the Buffalo Inn on Route 309 in Schnecksville. The discovery of his vehicle, miles from where he was last seen, offered no clues as to his whereabouts or what might have happened to him. The lack of any communication or activity from Ryan was entirely out of character, and as days turned into weeks, and weeks into years, the hope of his safe return began to fade. The Pennsylvania State Police have consistently suspected foul play in his disappearance, a belief that has persisted throughout the decades-long investigation.

The passage of time has done little to unravel the enigma of what happened to Ryan Kemp. Eight years after he vanished, in 1989, he was legally declared dead at the request of his mother, a somber acknowledgment of the painful reality that he was likely never coming home. Despite this legal status, the investigation into his disappearance remains open, a cold case that continues to trouble law enforcement and the community. The case is a poignant reminder of a life interrupted, a story without an ending. The overview of the case is one of sudden and unexplained absence, with the discovery of his abandoned vehicle being the only significant development. Foul play has long been the presumed reason for his disappearance, but without any concrete evidence or leads, the truth of what transpired on that September day in 1981 remains unknown, leaving only questions and a lingering sense of loss.
