An elderly ex-policeman confessed on Monday to being the violent serial prowler known as the "Golden State Killer," pleading guilty to 13 murders and admitting to dozens of rapes and break-ins that terrorized California during the 1970s and '80s.<br /><br />Joseph James DeAngelo, 74, entered the pleas as part of a broader deal with prosecutors sparing him from a potential death sentence in return for his admission to all of the offenses he stood accused of - charged and uncharged - in 11 California counties.<br /><br />Under terms of the unusual plea agreement, approved by Superior Court Judge Michael Bowman at Monday's hearing, DeAngelo faces life in prison without the possibility of parole rather than a potential death sentence.
