My mom works in the building across the street from the hospital where the victims were taken. She said it was crazy, all the sirens going off. She found out what happened pretty quickly because my brother works for a local news agency. I've been in that store multiple times over the years. It doesn't directly face any parking spaces, so it's not so likely that someone accidentally floored it while parking or anything. Apparently there were a few people who were laying outside the store, probably because they were on the sidewalk outside when the car came through.
