The former Los Angeles police officer suspected of killing four people in a shooting rampage is most likely dead. The giant manhunt in Southern California for Christopher Dorner is over as the suspect probably killed himself during a standoff with police on Tuesday in Big Bear Lake, near San Bernardino. Cornered in a remote cabin that caught fire after police shot tear gas through its windows, he may have taken his own life with a single bullet -- witnesses said they heard a single gunshot from inside the cabin --  as the wooden building burned.
