Nicholas Oswald, 45, was last seen in Las Vegas on August 9, 2025. He is described as a white male, about 6 feet 1 inch and 160 pounds, with brown hair and hazel eyes. At the time he disappeared he was reportedly wearing a black shirt and gray pants and his last confirmed contact was within the 89103 zip code.

Shortly after 1:00 a.m. he left his home intending to meet a friend at the wash area behind the Rio Hotel, an underground network of flood-control channels often called the tunnels. That destination is notable because the tunnels can become dangerous in heavy rain and investigators have focused on Nicholas’s movements toward that location. The Las Vegas Metropolitan Police Department’s Missing Persons Detail opened an investigation and entered his case into NamUs, but as of the last update the case remains unresolved.

If anyone saw Nicholas in the 89103 area on August 9, 2025, or has information about his visit to the wash behind the Rio Hotel, please come forward.
