On November 8, 1990, the body of 47-year-old Gary Donald Johnson was found inside his home in Centennial, Colorado. Johnson, a White male who worked in real estate, was determined by the Arapahoe County Sheriff’s Office to have died from blunt force trauma. Investigators classified the death as a homicide and opened a criminal investigation.

Despite the initial probe, the case went cold and remains unsolved. No arrests have been announced and no suspects have been publicly identified. The Sheriff’s Office continues to list the investigation as open and has asked the public to come forward with any information, however small.

If anyone knew Gary, observed unusual activity around his residence on or before November 8, 1990, or has information that could help, please contact the Arapahoe County Sheriff’s Office.
