Nancy Kerrigan's brother charged with attacking their father, who then died

it mentions in the article that the brother was intoxicated.it is completely possible that this was a fight over a phone. sometimes an addict (if he is one) can drive a parent or sibling over the edge. perhaps this 45 yr old man, that seemed to be living at home, was trying to use the phone in the middle of the night and his father had had enough and refused to let him? ive been around enough addicts to know how a small thing can turn ugly quickly.
