Sheriff's transcripts show that during the final two hours of the manhunt for ex-cop Christopher Dorner deputies didn't fire a shot while he was inside a mountain cabin.

There was a furious gunbattle shortly after Dorner arrived at the cabin on February 12. One deputy was killed and another injured.

San Bernardino County Sheriff's Department radio dispatch transcripts released Friday show law enforcement poured in but deputies were told not to fire unless they saw Dorner. They tried using tear gas to force him out and when that failed, incendiary gas was used.

Flames broke out. Minutes later a single gunshot was heard from inside. Authorities believe it was Dorner taking his life.

Dorner killed four people to avenge what he called an unfair firing from the LA police department.
