California Authorities Resolve 45-Year-Old Cold Case of Esther Gonzalez

After four and a half decades of uncertainty, the Riverside County Sheriff’s Office has identified a suspect in the 1979 murder of Esther Gonzalez, a teenager who disappeared while walking to her sister’s house. The suspect, Lewis Randolph “Randy” Williamson, initially claimed to have found her body and reported it to the authorities at the time.

On February 9, 1979, 17-year-old Gonzalez was last seen on her way to her sister’s residence in Banning, California. Sadly, she never arrived at her destination.

The following day, her body was discovered in a snowpack alongside a highway. According to a statement from the Riverside County District Attorney’s Office, she had been subjected to a brutal attack, including rape and being bludgeoned to death.

Witnesses noted that the unidentified man who reported the tragic discovery was “argumentative.” Williamson stated to the sheriff’s office that he was unsure about the identity of the victim. When authorities requested he undergo a polygraph test, he complied and passed, which at that time led to his exoneration in the eyes of investigators.

Decades later, advances in forensic genealogy breathed new life into cold cases, including that of Gonzalez. The specialized team utilized DNA sampling to piece together evidence, leading to Williamson being identified as the prime suspect in the ongoing investigation.

Forensic genealogy is gaining traction nationwide, enabling law enforcement to leverage both DNA testing and genealogical research as tools for solving previously intractable cases.

Sheriff’s Investigator Jason Corey emphasized the importance of these new methodologies, asserting that they enhance investigative efforts significantly. “It’s an invaluable tool that allows us to better understand and trace leads in unsolved cases,” he stated, expressing optimism for its future applications.

Despite the passage of time, Riverside County detectives remained dedicated to solving Gonzalez’s case. They continuously revisited the evidence, including a semen sample submitted to the Combined DNA Index System, but initially yielded no results.

In a major breakthrough this year, detectives sent several pieces of evidence to a Texas genetic lab renowned for its expertise in forensic genealogy. A meticulous review of the case-related data eventually led investigators to reconsider Williamson, who, although cleared through polygraph testing in 1979, had not been cleared through a DNA analysis due to prior technological limitations.

Williamson passed away in Florida in 2014, eliminating the possibility of conducting new polygraph tests. However, a blood sample taken at the time of his autopsy was retrieved, and comparisons revealed a match with the DNA evidence found at the crime scene.

Corey noted that the cold case unit had been actively working on Gonzalez’s investigation since its inception approximately five years prior. As the investigations culminated this past Wednesday, he expressed empathy for the Gonzalez family, reflecting on the enduring pain they experienced over the years.

“It’s difficult to fathom their journey—this pain has likely remained unchanged for them,” Corey commented. “While the identification might not bring complete happiness, it can provide an opportunity for closure.”

The resolution of this case has ushered in a sense of peace for Esther’s family, according to her sister Elizabeth, who expressed gratitude for finally receiving clarity about her sister’s murder. “We are very happy that we finally have closure,” Elizabeth stated, acknowledging the bittersweet reality that the suspect would not serve any time for the crime.

Elizabeth reflected on her sister’s essence, highlighting the close bond they shared growing up. Esther is fondly remembered as a gentle and humorous person in a family of seven children.

In a heartfelt message on social media, Esther’s oldest brother, Eddie, thanked the Riverside County Sheriff’s Department for their efforts, stating, “After 40 years, the Gonzalez family has closure.”
