On January 26th, 2013, Elisa Lam checked into the Cecil Hotel in Los Angeles. She was assigned a shared room, but fellow room occupants told the manager about her strange erratic behavior and she was moved to her own room. Surveillance footage from February 1st shows Lam cowering in the hotel elevator, peeking out into the hallway and quickly turning into the elevator again as if she were hiding from something or someone. Eighteen days later, her body was found in the water tank on the roof of the hotel, having drowned in it. It is still unknown how she got onto the roof (with the door being locked and alarmed), or how she got in the tank, which had no fixed access and was high enough that a ladder had to be brought up for workers to look at the water. The elevator footage of her case has received millions of views worldwide and can be seen here
