Cause of death: Alzheimer's + uncles
"Cornett lost his father to Alzheimer's disease, as well as a few uncles."
Hee-hee. I can picture the autopsy now: "Mr. Cornett died from a number of causes: Alzheimer's played a role, as did the multiple stab wounds he received from his four brothers."
How about: "Cornett lost his father and a few uncles to Alzheimer's disease."
Even then, I'm somewhat perturbed by the vague "few" uncles. Even if it's only three (what I consider the minimum threshold for "a few"), that's still quite a lot of brothers to be brought down by the same affliction.
