He died a few months after his wife died. My guess is he was distraught over her death and became depressed and stopped taking care of himself and allowed his diabetic condition to deteriorate, whether intentionally or not. The official record indicates complications due to a diabetic condition. I think he let his blood sugar stay too high for too long, and by the time he got medical attention, it was too late to save him. He was a good man, and he is missed.
