Remains found in a remote Nevada wash finally received a name, but the core mystery remains. On March 12, 1992, human remains were discovered in a remote part of Sand Canyon near Wellington and the man was long known as Sand Canyon John Doe. Forensic work later determined he had been murdered, probably in the spring or summer of 1991, and his body had been left in the desert for about a year before discovery.

Genetic genealogy solved the identification in 2020: the victim is Vincent Marion Trapp, a 43-year-old Caucasian man originally from Sacramento, California. Investigators reconstructed parts of his last-known movements, finding he lived in Topaz Ranch Estates and later Yerington, Nevada, prior to his death. Those inquiries produced persons of interest in two states, but no arrests have been announced and the homicide remains unsolved.

If anyone remembers Vincent Trapp, his time in Topaz Ranch Estates or Yerington, or has information about that area in 1991, please come forward with what was seen or heard.
