The man accused of being the Golden State Killer, facing a possible death sentence for a series of rapes and murders that terrorized California in the 1970s and ’80s, has offered to plead guilty in exchange for a life sentence, court documents show.

The suspect, Joseph James DeAngelo, was arrested in a suburb of Sacramento in April 2018 with the help of a genealogy website. He was charged with 13 counts of murder as well as multiple kidnapping and weapons charges.
