I have not found anything released except the mention that she was on medication. However, it was said (whether true or not I do not know) that she and a girlfriend had done coke during the week and had used alcohol steadily if not heavily. Ergo, I would bet that her system was significantly stressed. Add on top of all that her own meds (whatever they were), a week of little sleep, the possiblility of roofies, and you have a recipe for trouble.
When I think back to my youth and the way kids became spirited (if not plain wild) on graduation trips, I am surprised that we don't hear of much more trouble from Aruba.
Even good kids occassionally get the feeling that they are immortal and can take a break from their usual "good behavior"...and use some very dangerous drugs (coke and ecstasy, etc. are very dangerous). If there were ever a time for this, it would be on a senior trip to Aruba.
Whoa! I haven't heard anything about her doing coke? Do you know where that came from?
