Elisa Lam was a 21-year-old Canadian student at the University of Brish Columbia whose body was discovered in a water tank atop the Cecil Hotel in Los Angeles. She had been reported missing for over a month when maintenance workers finally discovered her body when the tenants began complaining bout the water supply. Her mysterious disappearance became an Internet phenomenon, which showcased elevator security footage of Lam talking and gesturing outside. Some claim that the video was evidence of Lam's bipolar disorder, others claim a paranormal explanation while a small minority believe the footage has been tampered with.
