A US soldier charged with murdering civilians and other crimes in Afghanistan has appeared in court while 11 other soldiers have invoked their constitutional right not to testify in the case. The Associated Press has reviewed statements Morlock made under oath in which he claimed Staff Sgt. Calvin Gibbs - who also faces charges connected with the incident - planned "scenarios" during which they could kill civilians. For example, Morlock said, if they came across someone in a village that had previously been flagged as having Taliban influence, they could toss a grenade at the civilian and claim they had been responding to a threat. Gibbs also illicitly collected "drop weapons" that could be placed by the bodies to make them appear to be combatants, Morlock and others said. "Gibbs had pure hatred for all Afghanis and constantly referred to them as savages," Morlock said in the statement. "Sometime after Christmas 2009, Gibbs gave me a (fragmentation) grenade and told me that if the situation presented itself that we should go ahead and run with the grenade scenario that he had briefed to us." Four other US soldiers were charged in June with the same murders as Morlock, and seven additional servicemen have been charged since then with other crimes stemming from the investigation, including conspiracy to cover up the killings. The soldiers are charged with keeping body parts, including finger bones, a skull, leg bones and a human tooth. Court documents say Morlock threatened a fellow soldier by showing him "fingers removed from a corpse."
