NBC News has fired a producer for editing a recording of George Zimmerman's 911 call the night he shot Trayvon Martin.

NBC had aired an edited version of Zimmerman's call from the night of Feb. 26. It was trimmed to suggest that Zimmerman volunteered that Martin was black. But the deleted portion had the dispatcher asking Zimmerman if the person was "black, white or Hispanic." Zimmerman responded, "he looks black."

A person with direct knowledge of the matter who was not authorized to speak publicly said Saturday on the condition of anonymity that the producer was fired. The producer was not identified. An NBC spokeswoman declined to comment.

The producer's dismissal follows an internal investigation that led to NBC apologizing Tuesday for airing the misleading audio.
