Denver Police solve four related cold case homicides that occurred between 1978 and 1981

The Denver Police Department and law enforcement partners today announced that through the continued determination of investigators, DNA evidence, investigative genetic genealogy and familial DNA search, the suspect in three Denver cold case homicides and an Adams County cold case homicide has been identified as Joe Michael Ervin (DOB: 6/25/51), who is deceased. The murders of three women and a teenage girl occurred in separate incidents between 1978 and 1981. The four cases were linked together and solved through several significant investigative developments beginning 35 years later. The final identification of the suspect in these four murders through Investigative Genetic Genealogy and familial DNA research was a result of Denver’s Integrated Cold Case Project. This project is funded in part through a 2020 Genetic Genealogy & Familial Match Searching grant, awarded to the Denver Police Department by the Bureau of Justice Assistance for a total of $470,000.
