Summary based on the NamUs case record (MP25994) and 4 other sources
In the summer of 1992, a 34-year-old man named Dz You Ying Pu, who also went by the alias Tommy Perea, vanished from his life in Lakewood, Colorado. He was the proprietor of a karate school located in the 5800 block of West Alameda Avenue, a space that doubled as his personal residence. The circumstances surrounding his disappearance are unsettling due to the conflicting timelines provided by those close to him. His girlfriend reported that the last time she saw him was on July 28, 1992. However, his family did not officially report him as a missing person to the Lakewood Police Department until over a month later, on August 29, 1992, after a prolonged period of no contact.

At the time he went missing, Dz Ying Pu was described as a White/Caucasian male, standing between 5'9' and 5'10' and weighing between 150 and 160 pounds. He had black hair and brown eyes. His hair was notably long, often worn in a ponytail that extended past his hips. He also had a distinctive potential feature: a tattoo of the word 'Ying' on his possibly shaved head. Since the day he was last seen, there has been no communication from him, and no one has come forward with credible sightings, leaving his family and investigators with a painful and enduring mystery.

The investigation into Dz Ying Pu's disappearance has remained open over the decades, but has yielded no definitive answers as to his whereabouts or what might have happened to him. The case is a cold case, a term for an unsolved criminal investigation which remains open pending the discovery of new evidence. To date, no one has seen or heard from Ying Pu, and the void left by his sudden absence is a source of ongoing pain for those who knew him. The Lakewood Police Department continues to hold the case file, hoping that one day a new lead will emerge that might finally shed light on the perplexing and sorrowful disappearance of Dz You Ying Pu.
