Vehicle belonged to Banchero. Story didn't clarify whether or not he was intoxicated. The guess here is either he was and it wasn't disclosed in the story, or he wasn't and was ignorant enough to let someone who was drive his vehicle. Bad move either way.
Wow. What a stupid mess. Made, IMO, even dumber when you consider that A) in the era of ride share, how difficult is it to make arrangements not to put yourself in that situation and B) given that the family isn't exactly scrambling to find breakfast in the morning, affordability is neither an issue nor an excuse.
