Elisa Lam, a Canadian student, went missing in January 2013 while staying at the Cecil Hotel in Los Angeles. Her disappearance gained widespread attention when a surveillance video of her acting strangely in the hotel's elevator was released. Several weeks later, her body was found in one of the hotel's rooftop water tanks. Her death was ultimately ruled as accidental drowning with bipolar disorder being a contributing factor, and no foul play was suspected. The case generated significant public interest and speculation due to the eerie video footage and the mysterious circumstances surrounding her death.
