Sources: Dorner Did Not Leave Burning Cabin

Authorities waiting for fire to die down to see if there's a body inside

A law enforcement official said the man believed to be fugitive ex-cop Christopher Dorner never came out of a California mountain cabin engulfed in flames.

The person who requested anonymity because of the ongoing investigation said a single gunshot apparently fired inside the cabin was heard just before the fire broke out Tuesday.

Officials were waiting for the fire to burn out before approaching the ruins to search for a body.
