Summary based on the NamUs case record (MP12971) and 5 other sources
Vaughn Martin Lueck, a 40-year-old man from Buffalo, Minnesota, disappeared on July 14, 1983. Lueck was last seen in the Buffalo area, but the circumstances surrounding his disappearance remain unclear. Standing 5'5" and weighing 127 pounds, with brown hair and brown eyes, Lueck had no known distinguishing marks or features that would aid in identifying him. His disappearance has left few leads, and no substantial clues have surfaced over the years.

Despite efforts to investigate, Lueck’s case remains unsolved. Authorities have no dental, fingerprint, or DNA information available for him, which has made the search challenging. The case has remained open for decades, with local authorities still urging the public to provide any information that might lead to understanding what happened to Lueck.

The Buffalo Police Department remains the primary investigative agency for this case, though no significant breakthroughs have occurred. The lack of concrete evidence has made it difficult for investigators to make progress, and the case continues to be one of the many unsolved missing person cases in Minnesota.
