OC-1 estimated that all the events since entering the wall had taken less than a minute up until this point, and that he had been the only American to fire his weapon. The soldiers threw an American grenade into the living quarters after first entering the complex.[27][43] Silver initially claimed that two Delta Force troops had opened fire, shooting all three of the shots into Khadr's chest, after the youth was seen to be holding a pistol and facing the troops.[20][28] These claims all directly contradict OC-1's version of events as the only eyewitness. OC-1 did agree however, that something was lying in the dust near Khadr's end of the alley, although he couldn't remember if it was a pistol or grenade.[27]
