Article Photos: Trying to unlock secrets of dead serial killer 4/14

FILE - In this file photo taken Dec. 4, 2012, in Anchorage, Alaska, Anchorage police Detective Monique Doll speaks at a news conference after confessed serial killer Israel Keyes committed suicide at the Anchorage jail.  Keyes showed no remorse as he detailed how he'd abducted and killed an 18-year-old woman, then demanded ransom, pretending she was alive. His confession cracked the case, but prosecutors questioning him soon realized there was more, he has killed before.  Before divulging more details, Keyes committed suicide in his cell.
