BAGHDAD (Reuters) - Relatives of an Iraqi girl who was raped and killed along with her family by a US soldier urged that he be given the death penalty on Friday. Private 1st Class Steven Green was convicted in a Kentucky court on Thursday of raping Abeer Qassim Hamza al-Janabi, 14, and killing her and her family near Baghdad in 2006. He faces a possible death sentence. Green, 24, was tried in federal court as a civilian for murder, rape and obstruction of justice charges since he was arrested after he was discharged from the US Army later in 2006 for a personality disorder. By all measures, this was a very criminal act. We are just waiting for the court to sentence him so he gets justice and the court can change the image of Americans, said Karim Janabi, the girls uncle. The trial featured prosecution testimony by Greens former comrades in which they detailed the assault, one of several incidents involving American soldiers that enraged Iraqis. So they decided this criminal was guilty, but we dont expect hell be executed. Only if hes executed, will it mean American courts are just, said relative Yusuf Mohammed Janabi. Green, 19 at the time of the crime, was described as the trigger-man in the group of five men, who donned black ninja outfits and raped Abeer Qassim Hamza al-Janabi, 14, and shot dead her and her father, mother and 6-year-old sister. Green, from Midland, Texas, was described by prosecutors as predisposed to killing Iraqis. The guilty verdict could go some way towards repairing the strained US-Iraq relations that the crimes caused. But relative Sawsen Najim al-Janabi said the courts took too long to convict him.
