A former U.S. soldier convicted of raping and murdering a 14-year-old girl in Iraq after killing her parents and younger sister has been found dead in his prison cell in Arizona. Steven Dale Green was found hanging in an apparent suicide. In 2006, he and three fellow soldiers went to the home of an Iraqi family, where Green killed three people, then joined his colleagues in the gang-rape of 14-year-old Abeer Qassim al-Janabi, before killing her. Three years later, Green was sentenced to life in prison, becoming the first U.S. soldier convicted under a 2000 law allowing U.S. soldiers and contractors to face prosecution for crimes committed abroad.
