Part 3/7:
The turning point came in June 2024 when Montgomery County detectives employed forensic genetic genealogy—a cutting-edge method that compares crime scene DNA to publicly available ancestry databases. Even if the suspect's DNA isn't directly listed, relatives can be identified, enabling investigators to build a familial map leading directly to the perpetrator.
In Leslie's case, forensic analysts traced the DNA trail to an individual in an Eastern European country. Through this process, they uncovered a distant relative linked to the suspect. This investigative lead ultimately pointed to Eugene Gregor, the ex-boyfriend of Leslie's daughter, as the prime suspect.
