US-CRIME-POLICE-INCIDENT

A California Highway Patrol officer guards a roadblock on Highway 38 near Big Bear Lake, California, on February 13, 2013 during a standoff with the former Los Angeles police officer Christopher Dorner. Authorities on Wednesday examined human remains found in a burned out mountain cabin to determine whether they belong to Dorner, a fugitive ex-cop wanted in at least four murders. Police discovered the remains in the cabin's charred ruins after a chase ended in a shootout with police and fire near Big Bear in the snow covered mountains east of Los Angeles where Dorner was thought to have taken refuge.
