Just my view without too much information but initial information. They got drunk, they got belligerent, they had sex, they were really drunk, what were the alcohol levels?, he said calm the heck down or I'm locking you on the balcony, time out?, the belligerence doesn't stop so he locks her out on the balcony, maybe he thinks it's funny, she's drunk and says FTS I'm leaving and tries to climb down, saw a picture where it looked like that was what she was doing and lost her footing and that's it. I don't see murder, I don't see mystery, I don't see anything but egos and attitudes on this one and copious amounts of booze. RIP little one, we should all make better choices and not display risky behavior. It is a lesson to all.
