Our biggest collaboration ever with DNA Justice is happening this weekend! If you're attending CrimeCon in Las Vegas, be sure to stop by the Sherry Black Foundation booth to learn more about how to upload your DNA profile to help solve unidentified remains cases. After you've uploaded to DNA Justice, check your email to see if case(s) you match are any of our six featured cases in this graphic. Your DNA could be the key to solving a case!

On November 3, 1986 approximately four miles west of Interstate 25, in the Midway Ranch area South of Colorado Springs the skeletal remains of an adult male were recovered. The man was believed to have been 5’4” to 5’7” in height, 30 to 40 years of age, and was wearing blue Calvin Klein Jeans and a blue/green sweatshirt at the time of his death. His cause of death was determined to be a gunshot wound. Traditional means of investigation failed to identify the man, and he became known as Colorado Springs John Doe.

In 2025, the Ramapo College Investigative Genetic Genealogy Center was consulted by the El Paso County EPC Sheriff's Office Sheriff’s Office Investigations Division Cold Case Unit to conduct investigative genetic genealogy to identify John Doe. Teeth belonging to John Doe were sent to Astrea Forensics for DNA extraction and SNP analysis, which resulted in the successful generation of a genotype profile for John Doe.

After several weeks of research, IGG staff members at Ramapo developed an investigative lead in the case: the identification of Peter Joseph Paskovich Jr. as the possible identity of Colorado Springs John Doe. Detectives from the El Paso County Sheriff’s Office in collaboration with the Colorado Bureau of Investigation confirmed the identity of Mr. Paskovich in April 2026.

More details about this case are available through the El Paso County Sheriff’s Office: https://epcsheriffsoffice.com/1986-homicide-victim-identified-after-nearly-40-years/

Last week our director David Gurney spoke during a panel on IGG at the Quattrone Center for the Fair Administration of Justice Spring Symposium. We look forward to seeing IGG utilized more frequently for miscarriages of justice as it continues to be adopted around the world.

Our collaboration with DNA Justice continues as their team prepares to head to CrimeCon later this month! At CrimeCon, six featured cases will be shared to encourage attendees to upload their DNA data to DNA Justice. Even if you won't be there, you can participate from home, too! Upload your DNA profile to DNA Justice to help solve cases using investigative genetic genealogy -- and if you find out you're a match to case #7592, you're a genetic cousin of Ajo Tattoos John Doe!

What is "The Koppelman Effect"? When Carl Koppelman creates a facial reconstruction of one of our cases, the new face for a John or Jane Doe helps the public to connect with their story. These images tend to be shared by hundreds of people across the social media sphere, increasing the chances that the right family might come across it. Do you recognize Ajo Tattoos John Doe? Take a close look at his teeth and his tattoos.

Thank you again to Carl for helping to add a face to the name "John Doe".

We're going down under! This weekend, two of our staff are headed to Sydney, Australia for a weeklong bootcamp event during which participants will work together to solve a genuine, unsolved cold case. We are so excited for this collaboration and we look forward to sharing updates as they happen on the ground in Australia!
