The moment was captured in a photograph and published in the Auburn Journal. SACRAMENTO - In 1979, Jerry Johnson was a teenager when his path crossed with Joseph DeAngelo’s. Please look at the time stamp on the story to see when it was last updated. “This is really tough,” Malia Fullerton, a University of Washington ethicist who studies DNA forensics, told The New York Times.This is an archived article and the information in the article may be outdated. But the news also raised fresh questions about privacy and genetic data in the digital age. For the next four months, investigators painstakingly constructed a family tree, which ultimately led them to the doorstep of 72-year-old grandfather Joseph James DeAngelo, a former cop and recently retired grocery store warehouse worker.ĭeAngelo’s arrest was widely celebrated, and it inspired many police departments to use genealogy databases to help solve crimes. That search surfaced the killer’s great-great-great grandparents. Holes took a DNA sample from the scene of a 1980 double murder in Ventura County attributed to the Golden State Killer and ran it through GEDmatch, a public genetic database. So Paul Holes, a retired cold case investigator, tried something relatively new: a genealogy website. His DNA didn’t match anyone in police genetic databases. I nvestigators were running out of tactics for tracking down the Golden State Killer. In an epilogue to her posthumously published book, I’ll Be Gone in the Dark, she addresses the killer directly, imagining the day police finally track him down and ring his doorbell: “Open the door. While McNamara didn’t live to see the Golden State Killer arrested, she suspected that the man was still alive. She left behind 3,500 files related to the case, 37 boxes of case files from an Orange County prosecutor, and dozens of other sources. In 2016, McNamara was working on a book about her quest to identify the Golden State Killer when she died suddenly in her sleep. She shared her findings with thousands of readers of her blog. But after her family went to sleep, she became, in her words, “something of a DIY detective,” scouring the web for “any digital crumbs authorities may have overlooked” in unsolved murder cases. Here’s how it happened.ī y day, Michelle McNamara was a stay-at-home mom living a quiet life with her comedian husband Patton Oswalt and their young daughter. Then, more than 40 years after his first crime, came a break in the case. Until a few years ago, Golden State Killer obsessives believed he might be among those able to elude capture indefinitely.

Serial killers, some experts believe, make up a sizable portion of those who haven’t been caught.

Professional investigators, too, had long been looking for the man, who was also known as Visalia Ransacker, the East Area Rapist, and the Original Night Stalker.Īccording to the FBI, murderers get away with their crimes about 40 percent of the time. By the time she started writing about him, the notoriously slippery criminal was already a subject of fascination among amateur sleuths. McNamara wasn’t the only one on the man’s trail. And she spent her evenings looking online for new details on his decades-old crimes, hoping to find the one hidden clue that might uncover his identity. She knew his shoe size and his blood type. McNamara’s interest in the case was all-consuming: She studied composite sketches of the suspect’s face. It was the first of many posts she’d pen in the coming years about a murderer and rapist she later named the Golden State Killer. It’s not healthy.” So wrote stay-at-home mother and writer Michelle McNamara on her blog, True Crime Diary, in 2011.
