Initially, U.S. Military officials implied the three women were killed prior to the raid by family members, reporting that the women had been found "tied up, gagged and killed." But investigators sent by the Afghan government reported, based on interviews and pictures of the scene, that the special operation forces removed bullets from the victims' bodies and cleaned their wounds as part of an attempted cover-up.
