If the grandmother survives, some of the questions may be answered. I also am concerned about how he gained access to the school.I'm waiting on the details. Three in particular:
1. What is it that the shooter originally set out to do? Seems he obviously had something in mind when he left the house.
2. Why was LE chasing him in the first place? Because of his Grandma? A tip or investigation?
3. How did he get into the school, and was it the Cafeteria or something? Lots of kids and staff, different ages.
