Elisa Lam was a 21-year-old Canadian student whose mysterious death in 2013 captured global attention. While staying at the Cecil Hotel in Los Angeles, she was last seen acting erratically in a hotel elevator, footage of which went viral online. Weeks later, her body was discovered in a water tank on the hotel roof after guests complained of low water pressure and odd-tasting water. Her death was ruled accidental drowning, with her bipolar disorder cited as a contributing factor, but the bizarre circumstances and lack of clear explanation have fueled widespread speculation and conspiracy theories.
