Video - The Mysterious Death of Elisa Lam: Secrets of the Hotel Cecil

In 2013, guests at the Hotel Cecil complained about dark, foul-tasting water. When maintenance checked the rooftop water tank, they discovered the body of 21-year-old Elisa Lam. Security footage showed Elisa acting strangely in the elevator hours before her death – pressing multiple buttons, peering into the hallway, and making unusual hand gestures. The autopsy ruled her death an accidental drowning. But major questions remain: How did she access the locked rooftop? How did she get into the water tank? And why did she remove her clothes before entering? The hotel has since been renamed, but Elisa's death continues to haunt its halls.
