Hi everyone. This is Brittney, Dennis' daughter. It is with great sadness that I want to tell you my dad passed away this morning after a long struggle with heart disease. He gave it a great battle but his heart was too weak to fight back anymore. God bless you all for your friendship to my father. Daniel and I miss him very much...he will never be forgotten. If you wish, you can leave messages on his page or contact me at britndan@sbcglobal.net
Sincerely, Brittney and Daniel Murphy.
