I'm really sorry to hear this, I know this has been tough on you (and Peter). He's at rest now, take some comfort in the fact that he's no longer suffering. Stay strong my friend.
Thanks everyone. Knowing it was coming, and when it actually happens are two different things. I feel sorry for his wife. She poured so much of herself helping him fight for 2 1/2 years. I think she needs a break more than anyone else.
