Dz You Ying Pu, who also used the name Tommy Perea, disappeared from Lakewood, Colorado in the summer of 1992. He ran a karate school that served as his residence in the 5800 block of West Alameda Avenue. His girlfriend last saw him on July 28, 1992, but his family did not report him missing to the Lakewood Police Department until August 29, 1992, after more than a month without contact.

He was described as a White/Caucasian male, 5 feet 9 inches to 5 feet 10 inches, 150–160 pounds, with long black hair often tied in a ponytail past his hips, brown eyes, and a possible Ying tattoo on a possibly shaved head. There has been no confirmed communication or credible sightings since he was last seen, and the investigation remains an open cold case.

Did anyone in Lakewood or the Denver area know him as Tommy Perea or have information about his movements that summer?
