From what I recall from her interview she walked towards him while firing and he fired several (three?) shots at her. She hit him and he went down but still had control of his weapon. She told him to drop the weapon and he didn’t, and then he reached for what looked like a hand grenade (possible smoke “bomb” similar to the others he tossed outside??). Anyway, as he was going for what she thought was a grenade she fired again. So perhaps his weapon did jam after he got a few shots off in her direction??
Thanks, geo. BTW - love your tag-line!
