"Close to midnight last Christmas Eve, a Blackwater security contractor named Andrew Moonen emerged from a boozy party in Baghdad's Green Zone and took a wrong turn on the way back to his hooch. There is as yet no satisfactory explanation for what happened next. An Iraqi guard named Raheem Khalif, who was protecting the compound of Vice President Adel Abdul Mahdi, was fatally shot three times. TIME interviewed three Iraqi guards who were on duty that night and reviewed two signed witness statements: all say the shooter was a white male, wearing an ID badge typically used by security contractors. The day after the shooting, Moonen was fired by Blackwater and flown out of Iraq. His name was not directly linked to the incident until earlier this month, when a Seattle lawyer told the New York Times he was representing Moonen, 27, a former Army paratrooper, in connection with the investigation into the shooting."
