Summary based on the NamUs case record (MP22760) and 5 other sources
In the late summer or early autumn of 1987, a 30-year-old man named Allan C. Hill vanished from the area of Yelm, Washington, leaving behind a life and a mystery that has endured for decades. Allan, a white male with brown hair and blue eyes, stood at six feet tall and weighed around 170 pounds. The last confirmed sighting of him was on September 18, 1987, at a tavern on Harris Road in Thurston County. Another account places his disappearance on October 9 of the same year, but what is certain is that after that day, he was never heard from again. His case is one of the many long-unresolved missing persons files in Thurston County.

At the time of his disappearance, Allan had been residing at a location off of Harris Road in the neighboring Lewis County. In a detail that speaks to the suddenness of his departure, all of his personal belongings were found left behind at his residence. This suggests that he had not planned to be gone for an extended period. His housemates later recounted to investigators that Allan had mentioned he was traveling to Seattle in September, but they had not seen him after he supposedly left for the city. The Thurston County Sheriff's Office has been the agency of record for this case from the beginning, holding the file on a man who seemingly stepped out of his life and into thin air.

Decades have passed since Allan Hill was last seen, and the trail has grown cold, with very few details available to the public. His disappearance remains a puzzle with many missing pieces. There is no information publicly available about his profession, his family ties, or his state of mind in the days leading up to his disappearance. The narrative of his last known moments is sparse, limited to his presence at a local tavern. The lack of information has made it difficult for a clear picture of the events of that day to emerge. The official investigation, led by the Thurston County Sheriff's Office, continues to hold his case file, a silent testament to a life interrupted and a family left without answers. The overview of this case is one of profound and unsettling ambiguity, a man who, for all public knowledge, simply ceased to be.
