California 1979 Cold Case Solved — He Reported It to Police Himself

In 1979, when the body of Esther Gonzales was discovered, police interviewed the man who found her. He seemed calm. He was cooperative. He even agreed to a polygraph test, but what investigators wouldn’t know for another 45 years is that they weren’t just interviewing a witness. They were talking to her killer.
February 10th, 1979. The San Jacinto Mountains of Southern California are covered in a pristine, deceptively peaceful blanket of snow. It’s a cold, crisp winter morning along Highway 243, a winding road that snakes through pines and canyons between the small towns of Banning and Idyllwild. But on this particular morning, something is terribly wrong.
A man driving along the highway, a local named Luis Randolph Williamson, known as Randy, pulls over. He spotted something unnatural against the landscape. A shape, partially hidden by a snowbank on the side of the road, just south of an area called Poppet Flats. It’s a body. He finds a phone and calls the Riverside County Sheriff’s Station in Banning.
But the conversation is strange from the start. Deputies would later describe the call using the word argumentative. He tells the dispatcher he’s found a body, but when asked for details, he’s difficult, claiming he can’t even tell if the person is male or female. Deputies race up highway. When they arrive, they find the scene just as the caller described.
There, partially covered in snow, is the body of a young woman. The cold has preserved the scene with a chilling stillness. It’s immediately clear this was no accident. The signs of violence are unmistakable. The victim is quickly identified as Esther Gonzales. She is only 17 years old. The deputies secure the perimeter as they begin the painstaking process of documenting the scene.
Every footprint, every disturbed patch of snow could be a clue. The serene mountain landscape has become the final resting place for a young woman whose life was stolen from her. And at the center of it all is the man who started the clock on this investigation, Randy Williamson, the witness, the one who found her. As investigators arrive and begin asking him questions, they can’t shake the feeling that something about him is off.
His demeanor, his strange phone call, it all hangs in the air. They have their first person of interest, but they have no idea just how close they are to the truth. Before she became a name in a case file, Esther Gonzales was a daughter, a sister, and a high school senior on the cusp of her future.
At 17, she was navigating that hopeful period of life where everything seems possible. She lived with her parents in Beaumont, a small city nestled in the pass between the mountains. She was the fourth of seven children. On Friday, February 9th, 1979, the day before her body was found, Esther had a simple plan. She was going to walk from her parents’ house in Beaumont to her older sister Elizabeth’s home in the neighboring town of Banning.
It was a familiar journey, a short distance between two points of family and comfort. But on this day, that short walk would become an impossible one. She said her goodbyes, stepped out the door, and walked into the final horrifying hours of her life. She never arrived at her sister’s house. As the hours ticked by, a quiet unease must have turned to frantic worry for the Gonzales family.
Phone calls were made, friends questioned. Where was Esther? The night would have been sleepless, filled with prayers and a growing dread that every family fears. The next day, their worst fears were confirmed with a knock on the door. The news was incomprehensible. Esther was gone. Found dead on a cold mountain roadside.
She hadn’t just been killed. She had been the victim of a brutal assault. An autopsy would later confirm she had been raped, bludgeoned, and beaten to death. The violence of the act was a stark, ugly contrast to the vibrant young life that had been extinguished. For her family, the world stopped. Her sister, Liz, would later reflect on the guilt and the what ifs that haunt survivors.
In an interview decades later, she said, “Sometimes I wish I would have followed her. If I’d known that was going to happen, I would have followed her.” Esther’s brother, Eddie Gonzales, was also thrust into this nightmare. In a town this small, connections were inevitable. He had gone to high school with the very man police were questioning, the man who found his sister’s body.
The idea that this person, someone from his own orbit, could be connected to such a horrific act was unthinkable. But at this point, all the Gonzales family knew was that their beloved Esther was never coming home. In the first hours and days of a homicide investigation, the focus is intense. For the Riverside County Sheriff’s investigators in 1979, the murder of Esther Gonzales was particularly grim.
A 17-year-old girl assaulted and left for dead in the snow. Justice needed to be swift. All eyes quickly turned to the man who inserted himself into the narrative, Luis Randy Williamson. The person who finds the body is always a person of interest. But Williamson was more than that. His behavior from the very first phone call had raised red flags.
His argumentative tone, his odd claim that he couldn’t tell if the body was male or female. It was suspicious. Why would a good Samaritan be so difficult with the deputies trying to help? Five days after Esther’s body was discovered, investigators formally identified the caller as Randy Williamson and brought him in for an official interview.
They wanted to understand his story. How did he happen to be on that specific stretch of Highway 243? What did he see? During the interview, the detectives’ suspicions likely deepened. Williamson was their primary, and at this point, only lead. The pressure was on to either solidify him as a suspect or clear him.
In the world of 1970s law enforcement, before widespread DNA forensics, investigators relied on a different set of tools. Intuition, interrogation, and what was then considered a powerful tool for seeking the truth, the polygraph test. The polygraph, or lie detector, measured physiological responses like heart rate and blood pressure as a subject was asked questions.
The theory was simple. Lying causes stress, and stress creates involuntary physiological changes the machine can detect. To much of law enforcement at the time, the polygraph seemed like a machine that could separate truth from deception. Faced with a suspicious witness, but lacking concrete evidence, the investigators made it a standard request.
They asked Randy Williamson if he would be willing to take a polygraph test. He agreed. For the detectives, this was a critical moment. The machine, they hoped, would tell them what they needed to know. Was this man a killer hiding in plain sight, or just an eccentric bystander? Williamson was hooked up to the machine, the needles poised over the rolling paper, ready to chart the hidden truths of his body.
The questions began. The polygraph room is an intentionally sterile space designed to focus all pressure on the person in the chair. For Randy Williamson, this was his chance to either confirm the investigators suspicions or walk away. The pens of the polygraph machine danced across the paper as a trained examiner posed questions about his involvement in the death of Esther Gonzales.
The investigators waited. They had a man whose behavior was deeply suspicious, who discovered the body of a murdered girl, and who was now being subjected to their most trusted truth-finding technology. The results came in. The examiner analyzed the jagged lines of Williamson’s physiological responses. The conclusion was stunning.
Lewis Randy Williamson passed the polygraph test. In 1979, that result carried immense weight. While not legally definitive proof of innocence, it was a major blow to the case against him. The machine they relied on had declared him truthful. In the absence of any other hard evidence, no other witnesses, no murder weapon, and no way to biologically link him to the crime, their primary line of inquiry collapsed.
A single piece of paper from the polygraph report became Williamson’s shield. Investigators had to let him go. He was, at the time, cleared of any wrongdoing. Williamson walked out of that police station having looked his accusers in the eye and beaten the machine. He had discovered the body of the girl he murdered, endured the suspicion, and emerged on the other side, seemingly untouchable.
He was a free man. Investigators would later learn he had a history of assault allegations behind him, but no convictions for violent crimes. Nothing that would have kept him on anyone’s radar. For the detectives, it was a devastating setback. Their only viable lead was gone. They were back to square one. The investigation would continue, but the trail was growing colder.
We now know that polygraphs are far from infallible. They don’t detect lies, they detect anxiety. A calm individual or a practiced liar can potentially pass one. But in 1979, that nuance was often overlooked. The machine had spoken, and the case of Esther Gonzalez began its long, slow descent into the cold case files.
The truth wasn’t lost, however. It was simply waiting. Preserved in a form that science had not yet learned how to read. A tiny semen stain collected from Esther’s body was carefully stored away as evidence. It held the killer’s biological signature, a silent witness waiting for its moment to speak. With Randy Williamson effectively cleared, the investigation into Esther Gonzalez’s murder stalled.
Leads dried up. For the world, the story faded. But for the Gonzalez family, time only deepened the mystery. They were left knowing that Esther’s killer was still out there. The case file, thick with reports and the one-page polygraph result that sent the investigation sideways, was eventually relegated to a records room.
It became a cold case, a term that sanitizes the raw, ongoing pain of an unsolved murder. Years turned into decades. Meanwhile, Randy Williamson lived his life. After being cleared, he continued on as if nothing had happened. A US Marine Corps veteran, he eventually moved away from California, relocating to Florida, thousands of miles from the snowbank on Highway 243.
He lived for another 35 years, a ghost hiding in plain sight. He died in Florida in 2014, a full decade before his name would resurface, taking his secret, he thought, to the grave. But while Williamson lived and died, science was marching forward. In the 1980s, DNA analysis emerged, revolutionizing criminal justice.
A DNA profile was eventually created from the preserved semen sample from Esther’s case, and searched against the Combined DNA Index System, or CODIS, a national database. But there was no match. Williamson had never been convicted of a crime that required his DNA to be entered into the system. So, the profile remained in the database, a digital ghost waiting for a name.
The silence continued. For 45 years, Esther Gonzales and her family were denied an answer. It would take another leap in science to finally break that silence. By the 2020s, the landscape of cold case investigation had been completely transformed by a revolutionary tool, forensic genetic genealogy. The concept is both simple and genius.
Investigators take the unknown DNA from a crime scene and upload it to public genealogy databases, the same sites people use to trace their ancestry. If the profile matches anyone, even a distant cousin, trained genealogists get to work. They build out family trees using public records to trace connections through generations until they can pinpoint a likely source of the DNA.
In 2023, the Riverside County Regional Cold Case Homicide Team decided to give Esther Gonzales’s case another look. This joint task force was armed with this powerful new technology. They pulled the decades-old evidence from storage and sent the semen sample to a private lab in Texas that specialized in this work.
Authum, the scientists at Authum faced a daunting task. DNA degrades over time, but their technology is designed for this challenge. They painstakingly extracted the remaining genetic material and used advanced sequencing to build a comprehensive DNA profile of the unknown killer. With the profile complete, the hunt began.
It was uploaded to genealogical databases and the search for a relative, any relative, commenced. Got a hit. Not a direct match, but a distant relative who had shared their DNA publicly. For the investigators, this was the first thread they could pull to unravel a decades-old mystery. The genealogists got to work, starting a process that would lead them back in time and ultimately to a familiar name from a 1979 police report.
The work of a forensic genealogist is like assembling a massive puzzle with most of the pieces missing. Starting with the distant relative, the team at Authum and the Riverside Cold Case Unit began building family trees. They poured over public records, tracing lineages back to find a common ancestor, and then forward again, looking for a man who would have been in the Banning, California area in 1979.
The trail eventually led them to a surprising place. They identified a woman who had passed away in Beaumont, California. The very same small town where Esther Gonzales’s parents lived. This was a huge geographical link. The genealogists dug deeper. They found a newspaper obituary for the woman, which listed the name of her son, the executor of her will.
His name was Lewis Randolph Williamson. For the investigators, it must have been a jolt. The name wasn’t new. It was right there, in the original case file from 1979. It was the name of the witness. The man who found the body. The man deputies once called argumentative. The man who was cleared by a polygraph test. For 45 years, the answer had been sitting in the file.
The first person they suspected was, in fact, the right person. The entire time, a flawed piece of 1970s technology had blinded them to the truth. As the District Attorney’s office would later put it, Williamson had been seemingly cleared by the polygraph in 1979. But he was never cleared through DNA, because the technology hadn’t yet been developed.
The feeling in the cold case unit must have been a mixture of elation and frustration. Elation that they had likely found their killer. And frustration that he had been right under their noses from the beginning. The good Samaritan who reported the crime was almost certainly the man who committed it. But a genealogical link, however strong, is not proof.
To close the case, they needed a direct DNA match. They needed to compare Williamson’s own DNA to the sample from the crime scene. And that presented one final major problem. Lewis Randy Williamson had been dead for a decade. The revelation that Lewis Randy Williamson was their prime suspect presented a new challenge.
You can’t get a DNA sample from a man who died in 2014. This required a final piece of brilliant detective work. Investigators started digging into the details of Williamson’s death in Florida. They discovered that an autopsy had been performed. And during an autopsy, it is standard procedure to collect biological samples like blood.
The question was, did those samples still exist? The Riverside County team reached out to the Brevard County Sheriff’s Office in Florida, where Williamson had died. They explained the situation. They were on the verge of solving a 45-year-old murder and believed Williamson was the killer. It was a long shot. Evidence from a routine death a decade prior may well have been destroyed.
But luck was finally on their side. The Broward County Sheriff’s Office confirmed they still had a blood sample from Williamson’s 2014 autopsy preserved in storage. That small forgotten vial held the key. With the help of Florida authorities, the blood sample was sent across the country to the California Department of Justice’s forensic lab.
There, scientists would perform the final decisive comparison. They would create a DNA profile from Williamson’s blood and match it against the profile from the semen stain found on Ester Gonzalez’s body 45 years earlier. The tension of waiting for that final result must have been immense, especially for the Gonzalez family who had been waiting nearly half a century.
After decades of silence and dead ends, the answer was just one test away. Then, the call came. The California Department of Justice confirmed an unambiguous match. The DNA from Louis Randolph Williamson’s blood was a match to the DNA of the man who had raped and murdered Ester Gonzalez in 1979. It was over.
After 45 years, the case was officially solved. The man who found the body was the killer. On November 20th, 2024, the Riverside County District Attorney’s Office announced to the world that they had finally identified Ester’s killer. The relentless work of detectives and the power of modern science brought an answer to a question that had haunted a family for nearly half a century.
If you find these stories of long-sought justice compelling, consider subscribing for more in-depth case analyses. The identification of Louis Randolph Williamson as the man who killed Esther Gonzales, brought an end to a 45-year mystery. But, it did not bring him to justice in a courtroom. Williamson died in 2014, cheating the legal system of the chance to hold him accountable.
He lived for 35 years after his crime, a free man. His guilt shielded by a faulty test and the limits of science. For Esther’s family, the news was profoundly bittersweet. In a written statement to CNN, her sister Elizabeth said, “We are very happy that we finally have closure. We are happy about it, but since the guy has died, a little sad that he won’t spend any time for her murder.
” Her brother Eddie, who had gone to high school with Williamson, told reporters he was very surprised because he didn’t think he was capable of doing that. In a public post, he added, “The Gonzales family would like to thank the Riverside County Sheriff’s Department on a job well done. After 40 years, the Gonzales family has closure.
This case stands as a stark lesson in the evolution of forensic science. It highlights the fallibility of older technologies like the polygraph, which can be deceived. And it serves as an incredible testament to the power of DNA and forensic genealogy, which can reach back across decades to pull a name from the silence. Most importantly, it underscores the value of preserving evidence.
The tiny biological sample, carefully collected and stored in 1979, became the most important witness in the entire case. Without it, the truth likely would have died with Williamson. But, the final thought in this case belongs to Esther Gonzales, a 17-year-old girl full of life, who went for a walk to her sister’s house and never made it.
Her life was not a statistic in a cold case file. It was a vibrant existence cut short by a brutal act committed by a man who then had the audacity to report his own crime. While the man responsible for her death escaped a trial, the truth at long last has been brought into the light. And Esther Gonzalez’s name is finally separated from the shadow of the man who took her life.
