In another case Wednesday, a Marine private who pleaded guilty to taking part in the murder of an Iraqi civilian was sentenced to 18 months in prison. The marine, Private First Class John Jodka, is the youngest and lowest-ranked of the seven charged for the murder of Hashim Ibrahim Awad in Hamdaniya. The marines shot Awad after pulling him from his home last April. They initially tried to cover up the slaying by placing a rifle at the scene to give the appearance Awad was an insurgent.
