"You're leaving your DNS in a place that's open to the public," she said.
The test result confirmed the match against more than 10 murders in California. Ms. Schubert's office then received a second sample and returned with the same positive result that matched the full DNA profile. Representatives of 23andMe and other Genetic Testing Services denied on Thursday that they had been involved in identifying the killer  The suspect, also known as the East Area Rapist, tormented his victims with sadistic rituals. Some he shot and killed with a firearm. Others were beaten to death with everything he could find ̵
Among the numerous serial killers who fought America in the 1960s, 1970s and 1980s – the Zodiac killer, son of Sam, to name only two – the Golden State killer was one of the most notorious.

Schubert was central to the search for the murderer. Her childhood in the Sacramento suburb of Arden-Arcade, just a few miles from the place where the suspect wandered through houses and wanted to rape women, was horrified to wonder if she or the people she was She knew that her parents were "not weapons," she said, but her father bought a firearm and her mother kept an ice pick under her pillow while she slept
Monica Miller, who was in charge of the Sacramento F.BI. Field Office from 2013 to 2017, said that when she retired, the case of the Golden State killer was cold. She said that Ms Schubert, "played a key role in convincing people that it was worth pursuing." For the people of Sacramento, she added, "It was almost an open wound, people would still talk about it, he was a phantom or a ghost in people's minds."
In her career as a district attorney, Ms. Schubert championed DNA technology and taught courses on cold cases. The Sacramento Procuratorate has set up a department to prosecute her. Eighteen years ago, she contacted an investigator from Contra Costa County who specialized in the East Area Rapist and began working to revive the case.
Two years ago, she convened a working group on the 40th anniversary of the attacks on the suburbs of Sacramento. It was the work of this group – working with counties in Southern California, the San Francisco Bay Area and the F.B.I. "That helped to solve the case," said Ms. Schubert.
There are many questions about the suspect. Do his family or former colleagues have clues to his gruesome past? Why did he seem to stop his wave of rape and murder in 1986? Did he use his job as a police officer to escape discovery?
All these questions got around in conversations between the residents of Citrus Heights, the neighborhood of Mr. DeAngelo. They woke up shocked on Wednesday when they learned that their neighbor, who wanted to tinker with his motorcycle in front of his neat, beige stucco house, was accused of being one of the most notorious serial rapists in America.
"It's crazy – she's been looking for this guy for 40 years and he was here under our nose," said Ashley Piorun, who lives five Mr. DeAngelo's homes. "We were shaken to find out."
This suburban neighborhood of manicured homes northeast of Sacramento is a classic Californian residential area with winding dead-ends and towering palm trees. Mrs. Piorun calls it a "quiet, sweet, boring neighborhood".
Paul Sanchietti, another neighbor, said he had been interested in the case six months ago, combing through the Wikipedia entry that committed all the gruesome and sadistic elements of alleged crimes accused of the Golden State killer ,
"Here I looked up the guy on Wikipedia and he was five doors down," Mr. Sanchietti said of Mr. DeAngelo.
From the outside, the house was meticulously maintained. The roof is new, the garden hose is perfectly wound up, the greening of lawn, wood chips and decorative stones is neat.
Mr. Sanchietti said he had had no more than polite interactions with Mr. DeAngelo for the last two decades, but like other neighbors, he remembered Mr. DeAngelo, who had a temper.
"He would escape," Mr. Sanchietti said. "He would take care of his car out here and he would get very angry." There were many four-letter words. "
" Every quarter has a weird little guy, "Mr. Sanchietti said. "But for him to be a serial killer and a rapist – that never crossed my mind."
