Esther Gonzalez, a 17-year-old girl, was raped and murdered in 1979, and her case remained unsolved for decades until new forensic techniques identified her killer.
Lewis Randy Williamson, initially a key witness in 1979, was identified as the perpetrator decades later through investigative genetic genealogy, linking him to the crime scene's DNA.
Investigative genetic genealogy utilizes crime-scene DNA to construct family trees, helping authorities identify potential suspects by tracing them back to relatives and known databases.
The Riverside County district attorney's office was able to connect the DNA from the crime scene directly to Williamson, a former Marine and the original discoverer of the body.
