Christopher Dorner Manhunt LIVE Video

UPDATE: The cabin Christopher Dorner is holed up in is currently "engulfed in flames" according to CBS Los Angeles.

Ex-Los Angeles police officer Christopher Dorner has allegedly killed four people. According to multiple reports, Dorner is holed up in a cabin in the San Bernardino Mountains. Although authorities had set up a roadblock, CBS Los Angeles is reporting that sources say they are "sure" that Dorner is still in the cabin. 

At a press conference held by the Los Angeles Police Department, police said the situation is ongoing and that details are "sketchy" at this point. The LAPD has sent officers to San Bernardino to assist police there if asked.
