AND . . . it is possible her sisters/friends/people she was around only saw that Jenny was perhaps drunk - they may very well had had no idea that she was in danger of DYING from alcohol poisoning along with the coke.
At this point, it is a tragedy, and the important thing is to get the word about drinking too much, the dangers of coke, and mixing the two. I would hope the Greek and college community would take this opportunity to schedule programming to do all they can to educate students to prevent it from happening again. If there is a signficant drug culture on the campus, this can be a wake-up call.
I am so sorry for the loss of a sister, and for the grief her parents friends and family must feel. It's just terrible, and I hope that something good can come of this terrible event.
