On the morning of March 8, 1975, 26-year-old Robert Peterson was working at the U-Totem convenience store at West 1st Avenue and Federal Boulevard in Denver when he was killed in what appeared to be a robbery. Peterson was a white male; investigators treated the death as a homicide and the Denver Police Department opened a murder investigation immediately after his body was found.

Detectives processed forensic evidence and took witness statements, but no suspects have been identified and police have not released descriptions of any persons seen nearby at the time. The case has gone cold over the decades with no arrests and no significant leads reported. The lack of identifiable suspects remains the primary barrier to answers for Peterson’s family.

If anyone has information about that store, the neighborhood around West 1st Avenue and Federal Boulevard in March 1975, or remembers unusual activity that morning, please share what is known with investigators.
