I suppose it could be a 96, but you're probably right with the 92.
I was surprised and disappointed that 4 rounds didn't end him.
From what I read or saw on the local news, it was a 9mm. I think it probably would have ended him had he not received immediate medical attention. Keep in mind that he was the last one shot, initially thought to have been one of the victims by the first responders, treated as such, and then quickly transported over to Scott & White hospital with the other seriously wounded.
Not to sound morbid, and maybe more facts will come out that completely change my opinion, but the results of the 5.7 didn't put it on my short list of defensive handguns. With what was reported as well over 100 rounds fired at unarmed folks, at close range, in confined areas, the guy shot approximately 44 people, multiple times for some if not most, of which 13 died, and 31 were wounded. Of those wounded, as of yesterday, 27 had already been treated and released. Some of those shot said they were not even initially aware they had been hit.
