I honestly feel like something happened at the party that isn't being disclosed. The party-goer's use of the word 'coherent' sounds like legalese to me. It's too ambiguous. Combined with investigator's exclusion of party details makes me wonder if there is something more going on. Perhaps the most bothersome part of this case is that it will likely never be disclosed what actually happened - once the investigators do figure it out. Out of respect for the family and the deceased, it's common in this area to withhold any information which may put the individual in a bad light. I know of multiple DUI related car deaths in the area which involved drug or alcohol use but this was never disclosed in the press releases. Very common to see with overdoses too.
