- Ronan Wolfe: Welcome to *Case Cracked: The Clues That Led to Justice*, the AI-powered true crime podcast where digital detective Ronan Wolfe breaks down real-life cases and the clues that led to justice. Today, we uncover how a decades-old mystery was finally solved. It took over 40 years to track down the infamous Golden State Killer, but in 2018, one piece of DNA changed everything. This is how genetic genealogy helped crack the case. Ronan Wolfe: The Golden State Killer terrorized California for over a decade. From 1974 to 1986, he committed at least 13 murders, more than 50 sexual assaults, and over 100 burglaries. He was a phantom, leaving behind terrified victims and frustrated investigators. He struck without warning, often stalking his victims before breaking in at night, tying them up, and committing his horrific crimes. His ability to elude authorities made him one of the most feared serial predators in history. Ronan Wolfe: His crimes spanned multiple regions, and for years, law enforcement agencies struggled to connect them. He would sometimes call his victims afterward, whispering threats or breathing into the phone, instilling fear long after the attack. Witnesses described him as calculated, prepared, and relentless. Despite extensive manhunts and numerous composite sketches, he remained unidentified. Ronan Wolfe: Law enforcement had evidence—DNA samples from various crime scenes—but for years, they had no match. Without a name, he remained a ghost. The case went cold. Detectives followed thousands of leads, but each one led to another dead end. Families of victims were left waiting for justice that seemed out of reach. Ronan Wolfe: Decades passed. Then, in 2018, detectives turned to an emerging technology: genetic genealogy. Investigators uploaded DNA from a crime scene to a public ancestry website called GEDmatch, which allows users to share their DNA to trace family roots. This was a revolutionary approach—one that had never been used before in a high-profile criminal case. Ronan Wolfe: A distant relative of the Golden State Killer had submitted their DNA, unknowingly opening the door for investigators. Using a complex process of building family trees, detectives meticulously traced the suspect down to one man: Joseph James DeAngelo, a former police officer living in a quiet Sacramento suburb. Ronan Wolfe: With DeAngelo in their sights, detectives needed confirmation. They surveilled him and collected his DNA from a discarded item—reports say it was a tissue from his trash. When they ran the test, it was a perfect match to the crime scene DNA. Ronan Wolfe: The decades-long mystery was over. Ronan Wolfe: On April 24, 2018, authorities arrested Joseph James DeAngelo, unmasking the man behind one of the most infamous crime sprees in U.S. history. When confronted, DeAngelo didn’t resist. Instead, he muttered to himself, whispering about an alter ego named "Jerry," as if blaming someone else for his crimes. This bizarre behavior left many wondering if his cold-blooded actions had been the result of a split personality or just another manipulation. Ronan Wolfe: In 2020, DeAngelo pled guilty to multiple murders and kidnappings, avoiding the death penalty in exchange for life in prison without the possibility of parole. Families of victims filled the courtroom, some speaking directly to him, ensuring he finally faced the pain he had caused for decades. Ronan Wolfe: His capture was a landmark moment for forensic science. The use of genetic genealogy has since led to breakthroughs in numerous other cold cases, proving that even the most elusive criminals can leave behind an invisible trail. What was once considered a long shot is now a powerful tool in the hands of law enforcement, offering hope to victims and their families who still seek justice. Ronan Wolfe: And that’s how justice was served in the case of the Golden State Killer. A single DNA match, hidden for decades, finally led to his arrest.
