The company said in a statement on Friday that they had no idea its services were involved in the manhunt for the Golden State Killer and they were never contacted by law enforcement or anyone else about this case or the DNA profile that was used.
Investigators were able to make the arrest this week after matching crime-scene DNA with genetic material stored in an online database by a distant relative.
Officers could then have established that ancestor's family tree before looking through it to find likely suspects.
Ward doesn't recall DeAngelo directly working on the case.
"While we take our customers' privacy and confidentiality extremely seriously, we support ethically and legally justified uses of groundbreaking advancements of scientific research in genetics and genealogy", company officials said in a statement.
Oswalt added that he'd like some answers from the famous killer that his late wife always wanted to know.
DeAngelo was a former police officer whose law enforcement career ended after he was busted for shoplifting in 1979.
Salazar believes DeAngelo is the so-called Visalia Ransacker who terrorized the farming community about 40 miles (64 kilometres) south of Fresno in 1974 and 1975. I hope THEY got him'.
It was DNA that also led to the Monterey County arrest in 2017 of Charles Holiefield, for the kidnapping and murder of 13-year-old Christina Williams of Seaside, some 19 years before.
Detectives believed the homicides in Sacramento and Southern California were connected but they could not prove it.
Huddle told The Associated Press it is "still just going insane in my mind".
He told Oxygen.com that he couldn't remember who brought up the subject.
Natalia Bedes-Correnti said the suspect appeared to be a "nice old grandpa" who lived with an adult daughter and granddaughter. The 72-year-old looked dazed and spoke in a faint voice to acknowledge he was represented by a public defender.
Oswalt and McNamara's fans couldn't help but notice the parallels with DeAngelo's arrest and how her book ends, with a message directly to the Golden State Killer.
Shaun Hampton, a Sacramento County Sheriff's department spokesman, also told CNN that investigators used sites that collect DNA information.
"An vast investigation is ongoing as we speak", Totten said.
She was attacked in her home in the Sacramento suburb of Citrus Heights. The case had baffled investigators for more than three decades.
DeAngelo has not entered a plea. By the next day, authorities identified him as the Golden State Killer, citing DNA evidence, according to the New York Times.
She called police, who quickly arrived and asked her for details.
McNamara dedicated her life to the case of the Golden State Killer - a name that she herself coined.
For her, learning that her mother's murder was part of a series of attacks was "comforting" in an odd sense, she said.
Two years ago, nearly to the day, crime writer Michelle McNamara was found dead in her Los Angeles home.
Reamer, who now lives in DE, is the mother of an Associated Press reporter. "Mary" says she will not go to court.
McNamara built such positive relationships with law enforcement officers that several of them attended her funeral in 2016 and "talked about her in a attractive way", Skrine said.
"He'd say 'do you want me to kill you?' and I said 'I don't care.' And I just knew I wasn't going to give him that satisfaction".
"After she learned that DeAngelo had been arrested, she dreamed about what she saw all those years ago".
Billy Jensen, the journalist who worked with Michelle McNamara, the late researcher and author of the bestselling book I'll Be Gone In The Dark, has confirmed to The Daily Beast that an extra chapter will be added to the paperback, covering the major arrest of DeAngelo.
Now that a suspect in the killings has been identified, Mr. Oswalt said he felt a odd mix of elation and impending sadness that Ms. McNamara wasn't alive to witness it.
When questioned about the book's impact on the investigation, Sacramento County Sheriff Scott Jones said that I'll be Gone in the Dark did not factor into the arrest.
AP writer Michelle A. Monroe contributed to this report.
DeAnglo has so far been charged with six counts of murder. He is suspected of killing 12 people and raping about 50 and could face more charges.
After decades of pain and loss, the families of the East Area Rapist's victims finally have closure.
Initially, police didn't suspect a serial killer.
