I was grieved about the deaths of of Sergeant Mark Renninger and Officers Ronald Owen, Tina Griswold, and Greg Richards. The heartfelt appreciation of a truly grateful American citizen goes out to their families and friends. You have my sympathy condolences, and prayers during this time of grief. They are true heroes, and I hope the fact that they are honored by so many brings you some comfort in this time of loss. May they feel the comfort and love from across this nation embrace and hold you up during this difficult time. We will not forget them and will forever be in their debt for what they have done for us.
