This is heartbreaking and so confusing for me to try to get my mind around. Hours went by between the shootings and yet classes went on with access doors unlocked (or it seems so since this gunman moved freely across campus and into another Hall)? I just watched video from someone's cell phone and you can hear the shots ringing out. It's beyond horrifying to think what each shot means.

I cannot begin to imagine the horror of this for the students, faculty and their families. They are in my prayers.
