SACRAMENTO, Calif., April 26 (Reuters) - Investigators in California narrowed in on the Golden State Killer suspect by using the genetic profile of a relative on ancestry websites that solicit DNA samples from users, a Sacramento County prosecutor said on Thursday.
The suspect, identified as former police officer Joseph James DeAngelo, 72, was arrested on Tuesday outside the Sacramento-area home where he has lived for at least two decades. He is accused of committing a dozen murders, 45 rapes and scores of home invasions in a crime-spree spanning 10 years and 10 California counties during the 1970s and 1980s.
