Leanne

The boyfriend seems SUPER shady, as does his friend, but I'm surprised that no one has speculated that she was maybe afraid of something or someone and in her confused state, thought that the chute was an alternative route out of the building. Perhaps she had no idea there was a compactor at the bottom, and in her extremely drugged/drunken state she saw it as something she could slide directly down to the ground floor. If he was out at the time, maybe she thought he was on his way back and she wanted to get away fast and didn't want to encounter him on the stairs or elevator. It seems pretty crazy, but who knows how she was interpreting her reality at that point whilst so under the influence :( Such a tragedy.
