Just Solving Cold Cases With Forensic Genetic Genealogy

In episode four of our Case Studies: Part 1 mini season, Just Science sat down with Leighton D'Antoni, the Assistant District Attorney in Dallas County, Texas, to discuss how forensic genetic genealogy was used as an investigative tool to help solve a series of violent cold cases. In the 1980s, several violent sexual assaults occurred in Dallas County, Texas and Shreveport, Louisiana. These cases were all linked by a foreign DNA profile; however, no suspect was found, and the cases went cold. In 2020, the investigations were re-opened, and forensic genetic genealogy was used to help identify a common suspect in all six cases. Listen along as Leighton discusses the journey to bring justice to survivors almost 40 years later and the prospects of using forensic genetic genealogy as a tool to help solve previously unsolvable cases.
