NEW YORK (AP) — Three employees of NBC or an NBC-owned television station have now lost their jobs because of editing changes to a call made to police by George Zimmerman on the night he shot Trayvon Martin.The network said Miami-based correspondent Lilia Luciano lost her job. This came as a result of her March 20 "Today" show report on the case.In two reports on "Today" and a separate one on NBC's Miami affiliate WTVJ, changes were made to audio of Zimmerman's phone call to a police dispatcher that emphasized the neighborhood watch volunteer's identification of Martin as black. Zimmerman has been charged with second-degree murder in the February shooting of Martin in Florida, a case that has increased racial tensions.Last week WTVJ aired an apology for its report.
