The thing I find somewhat odd of the story, is if the facts are accurate, what's even the point of the trump arguement. It feels like the article is flooded with basically details not directly related to the shooting. The "relapsed alchoholic that had 2 glasses of wine", the topic of the arguements (and even the specific things said in them).

Actual relevant facts of the shooting.

Dad had an arguement with the daughter.

Several hours later they had an arguement on guns, Dad brought out gun to show her... then claims he accidentally shot her.

Point is the arguement doesn't really hold relevance, Dad either horribly mishandled the firearm, in which case the situations up to it were irrelevant.

Or dad murdered his daughter in a fit of rage.
