A Marine sergeant was ordered Friday to stand trial on charges of unpremeditated murder and dereliction of duty in the killing of an unarmed detainee in Fallujah, Iraq. Lt. Gen. Samuel Helland ordered the court-martial of Sgt. Ryan Weemer after finding there was sufficient evidence to send him to trial. Weemer is one of three current and former Marines accused of breaking rules of engagement and killing four men they had captured after a platoon commander radioed to ask whether the Iraqis were "dead yet." The killings occurred in November 2004 during the invasion of Fallujah, one of the fiercest ground battles of the Iraq war.
