Your son was the first thing that crossed my mind when I saw the news break this afternoon.
We missed all the local and national news this evening due to nearby tornadoes and half dollar sized hail and lighting that was pretty bad. I unplugged all the stuff I could get to and we rode it out for a long time. It kept coming in waves of more storms but seems to be gone now.
Local news will be on a few minutes so I can learn more about the shooting.
