Libyan investigators leave the U.S. Consulate, in Benghazi, Libya Saturday, Sept. 15 2012 after finishing their investigation regarding the attack that killed four Americans, including Ambassador Chris Stevens on the night of Tuesday. The American ambassador to Libya and three other Americans were killed when a mob of protesters and gunmen overwhelmed the U.S. Consulate in Benghazi, setting fire to it in outrage over a film that ridicules Islam's Prophet Muhammad. Ambassador Chris Stevens, 52, died as he and a group of embassy employees went to the consulate to try to evacuate staff as a crowd of hundreds attacked the consulate Tuesday evening, many of them firing machine-guns and rocket-propelled grenades.
