Summary based on the NamUs case record (MP2657) and 8 other sources
On a summer day in August 2001, twenty-year-old Harold Clifton Cooper III was last seen in Bladensburg, Maryland. The specific date was August 19, 2001, when he was in the 3600 block of 55th Avenue. At the time of his disappearance, Harold was seen getting into a white, four-door 1992 Chevrolet Caprice with an acquaintance. He was wearing a gray Harley Davidson t-shirt, gray sweat shorts, and black swimming shoes. Before he vanished, Harold made a phone call to his grandmother, telling her he was on his way to visit her at her home in Virginia. However, Harold never made it to his grandmother's house and has not been seen or heard from since that day.

Harold grew up in Washington D.C., where he attended Anacostia High School. He was the oldest of five siblings and was described as being very protective of his mother, especially after his father was tragically murdered when Harold was just a child. At the time he went missing, he was working at a warehouse. His family has kept his memory alive, with his mother even celebrating his 30th birthday with his favorite food and music in his absence. The pain of his disappearance remains fresh for his loved ones, who still hold out hope for his return.

The circumstances surrounding Harold's disappearance remain unclear, and authorities have considered the possibility of foul play. The Prince George's County Police Department has investigated the case, re-interviewing friends and family over the years. Despite their efforts, his case remains unsolved. There is a discrepancy among some agencies regarding the exact location of his disappearance, with some reports stating he vanished from Fort Washington, Maryland. The investigation has explored various possibilities, including an accident, but so far, no evidence has emerged to provide definitive answers. This lack of resolution has left his family in a state of prolonged uncertainty. The case of Harold Clifton Cooper III is a somber reminder of the many individuals who disappear without a trace, leaving behind families to grapple with unanswered questions and the enduring hope for closure.
