SOURCE: Suspect Never Emerged From Burning Cabin

LOS ANGELES (AP) -- A law enforcement official tells The Associated Press that 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.

Authorities believe Dorner barricaded himself in the cabin after exchanging gunfire with deputies, killing one and wounding another.
