LOUISVILLE, Ky. – Facing life in federal prison with no chance at parole while carrying a conviction of raping and killing a 14-year-old Iraqi girl, a former U.S. soldier hanged himself in his cell in Arizona. Steven Dale Green, 28, of Midland, Texas, did not leave a note explaining the reason for taking his own life over the weekend. He died five years after a federal jury spared him a death sentence in the attack on the teenage girl and the shotgun slaying of her mother, father and younger sister near Mahmoudiya, Iraq, in 2006.
