bam. i just started running. everyone said this is no drill. go, go, go. emergency exits now. go, go g. people were yelling to close the doors, lock the doors. we heard a very loud gunshot very close by and we looked up and we saw bullet holes in the wall to the conference that we were in about a foot down from the ceiling. he was far enough down the hall that we couldn t see his face but we could see him with a rifle and he raised and hit high on the wall. as we came outside, people were climbing the wall trying to get out over the wall to get out of the spaces. it was just crazy. reporter: we will have much more on alexis and his history this morning. he had an ar-15, a rifle. he also had a semiautomatic clock and handgun with him and third weapon. it is believed the ar-15 was the main murder weapon. that was the same weapon used by adam lanza and james holmes.
