  1. JJ, surely you are missed just as you were the day you retired as a Trooper. Clearly one of the best I ever worked with. We both got to witness a new generation trooper arriving and I will never forget you saying" they need to be issued mothers along with their equipment". A class act, farewell my friend.

  2. Very good friend of mine, as we often worked together in Law enforcement, RIP JJ.

  3. JJ was a good neighbor, friend and customer who helped keep Stannards a safe neighborhood.

    Condolences to John's family. He was a great guy as a trooper and at Hart's. His sense of humor made Hart's visit more comfortable. Sorry for your loss. Know you will see him again some day!
