The one used in the shooting of the doors was a Kel-Tec 2000 in 9mm. It is a rifle (16.1" barrel) which folds in half. The other she carried slung looks like a 5.56mm "pistol" (barrel shorter than 16"). Her other pistol was a Smith & Wesson Shield EZ, another fine weapon.
She had "good taste" in firearms. They cost money and required some practice to handle as she did. She also acted and moved like she had some training as there was no hesitation or lack of deliberation. Did she have some guidance and planning from someone? It is pretty obvious this was not some spur of the moment mass murder. My guess is there is more to this than meets the eye today.
I agree.
