Break in Golden State Killer case came from DNA on genealogy website

Break in Golden State Killer case came from DNA on genealogy website

The man suspected of being the Golden State Killer was arrested after investigators compared DNA collected from crime scenes to genetic information on genealogy websites, according to a spokeswoman with the Sacramento County District Attorney's Office. It's important to note that in all of 2015, 2016, and 2017 we received no valid legal requests for genetic information.

"Amazing that they caught him after all this time", Inouye said.

He did not address whether the websites volunteered the information or were subject to a search warrant or subpoena. A spokesperson for 23andMe, a well-known genealogical website, said it was not involved in the investigation. He lived in the areas where the crimes happened and fit the right age range.

Detectives matched a discarded DNA sample from his home to DNA evidence from the investigation, authorities said Wednesday.

"Very possibly he was committing these crimes during the time he was employed as a peace officer, and obviously we'll be looking into whether it was actually on the job", Sacramento County Sheriff Scott Jones said.

The Golden State Killer, also known as the "East Area Rapist" and "Original Nightstalker", is suspected of carrying out at least 12 murders and 45 rapes in California between 1976 and 1986, according to the Federal Bureau of Investigation. Officers surveilled DeAngelo for several days prior to his arrest. "It happened nearly instantaneously".

DeAngelo is accused of being the man who killed 12 people and raped more than 50 women in the 1970s and 1980s.




The DNA was available in public family trees in an online database and was used to match to samples in rapes committed by the infamous East Area Rapist.

"He would be outside in his driveway working on his vehicle or something, and he would go into these really loud tirades, Sanchietti said, adding that he nevertheless was unaware of DeAngelo ever running afoul of law enforcement".

Ancestry.com and 23andMe, two of the largest companies that produce genetic profiles for customers who provide DNA samples, say they don't cooperate with law enforcement unless they receive a court order.

The use of DNA technology in DeAngelo's arrest highlights the progress that law enforcement agencies in California have done in their use of forensic science.

DeAngelo, a Navy veteran, has been charged in eight murders.

His crime spree ended in 1986.
