Elisa Lam

Elisa Lam (born Lam Ho-yi) was a 21-year-old Canadian student from Vancouver, British Columbia, who had attended the University of British Columbia. She had been diagnosed with bipolar disorder and depression, for which she was prescribed several medications. In January 2013 she was traveling alone along the West Coast of the United States, reaching Los Angeles on January 26 and checking into the Cecil Hotel (then also marketed as the Stay on Main) in the city's downtown on January 28. Hotel staff later described some unusual behavior, and after roommate complaints she was moved to a private room. She was last seen alive on January 31, 2013, her scheduled checkout date, when she failed to make her usual daily contact with her parents, who then alerted police.

The Los Angeles Police Department publicized the disappearance in early February and, on February 13, released roughly two and a half minutes of hotel elevator surveillance footage recorded on January 31. In the clip Lam is alone, pressing multiple buttons, stepping in and out, appearing to look or hide from something in the corridor, and gesturing with her hands. The video spread rapidly online, drawing millions of views and worldwide attention. On February 19, a maintenance worker inspecting the roof after guests complained of low water pressure and discolored water discovered Lam's body inside one of four large water tanks that supplied the hotel's rooms.

The Los Angeles County coroner ruled the death an accidental drowning, with bipolar disorder listed as a significant contributing condition. An initial autopsy on February 21 was inconclusive as to manner of death; the finalized report, released in June 2013, confirmed the accidental ruling. Investigators found no evidence of physical trauma, sexual assault, or suicide. Toxicology detected prescription medications at levels suggesting she had not been taking them as directed, along with over-the-counter products and only a trace of alcohol, but no recreational drugs. Her clothing was found floating separately in the tank, coated with a sand-like particulate.

Because the roof was described as secured and the tanks difficult to access, the case generated intense online speculation. Theories circulated tying the death to the paranormal, to a supposed "elevator game," to foul play by an unidentified pursuer, or to eerie coincidences involving the hotel's grim history and even the similarly named LAM-ELISA tuberculosis test. None of these theories was ever substantiated by investigators, and authorities maintained there was no evidence of foul play. Her parents filed a wrongful-death lawsuit against the hotel in September 2013; it was dismissed, with a judge ruling the death was not foreseeable because Lam had entered an area guests were not permitted to access.

The case left a lasting cultural footprint, inspiring extensive amateur online investigation and numerous references in television, film, and music, and was the subject of the 2021 Netflix docuseries "Crime Scene: The Vanishing at the Cecil Hotel." Despite the official ruling of accidental death, the unresolved questions about how Lam entered the tank have kept the case a persistent subject of public fascination and speculation. Its recorded status remains contested in popular discussion even though the coroner formally classified the manner of death as accidental.
