The school released the following statement:

There are no words that can express our sorrow and pain at the senseless loss of one of our own, Philip Nelson. Philip was not only a colleague and friend to many of us, he was also a loving son and father. I know our students and we will keep trying to find explanation for what isn't explainable. With that, I hope we will find a way at this very difficult time to focus on Philip's kind and beautiful spirit. He was truly a special person. Although gone, he left us a special gift through his life and memory and that is to love our students and each other even more. As we process what has happened, we will focus our attention on our students by providing them with our support, and with access to grief counseling. Our deepest condolences go out to Philip's family and friends.
