"I saw The Who at Staples and stayed here that nite. Checked out the day the girl disappeared. The whole place had a creepy vibe. The place has 2 elevators, 1 of which was out of service that nite. That might be the elevator she was in when she pushed all the buttons yet didnt go anywhere. The other elevator was very slow so I took the stairs instead. Later I heard that the stairs were the way to get up and down without being seen by the cameras. I also stayed on the 4th floor where a witness said he heard a loud bang above( he was on the 3rd floor). Those 2 facts make me surprised that I havent at least heard from he cops once. You would think someone who used the stairs instead of the elevator multiple times and who stayed on the floor where a loud bang was heard would at least hear from the cops once. That tells me that these guys are keystone cops and explains why they think this was an accident and not a murder."

Not sure exactly what this adds, but I found it interesting.
