Mintz describes the attack in a Facebook post (link). He says he was in an adjacent classroom in Snyder Hall when everyone heard yelling. When they heard gunfire, Mintz held the door as everyone fled.
All of a sudden, the shooter opened the classroom door beside the door to my left, he leaned half of his torso out and started shooting as I turned toward him. He had a black shirt on, a shaved head, was tan and wearing glasses, he was so nonchalant through it all, like he was playing a video game and showed no emotion. The shots knocked me to the ground and felt like a truck hit me. He shot me again while I was on the ground and hit my finger, and said “that’s what you get for calling the cops” and I laid there, in a fetal position unable to move and responded “I didn’t call the cops man, they were already on the way.” He leaned further out of the classroom and tried to shoot my phone, I yelled “its my kids birthday man” he pointed the gun right at my face and then he retreated back into the class. I’m still confused at why he didn’t shoot me again.
I have to thank all the people who responded and everyone in the hospitals. THEY are the real heros, they saved us. I was shot five times, once in the left leg(breaking my femur) once in the right leg(breaking my tibia and fibula) once in the abdomen that exited my right hip, once at the top of my shoulder blade(it is still in my back, broke off part of my scapula and was about an inch from my aeorta) and finally my left finger(shattering the mid-joint of my ring finger.) Although I am not completely sure, I believe the caliber was a 38.
I am recovering well and thank everyone for their thoughts and prayers.
