In February 2013, this 21-year-old student from Vancouver, Canada, was found dead inside the Cecil Hotel’s rooftop water tank in Los Angeles. The L.A. County Department of Coroner ruled the death “accidental due to drowning” and said no traces of drugs or alcohol were found during the autopsy. However, there is much more to the story than what is implied by police reports. The first piece of evidence that needs to be considered is an elevator surveillance tape that recorded Elisa’s behavior only a few moments before she lost her life.
LA authorities ruled in June 2013 that Elisa Lam’s death was accidental and that she was “probably bi-polar”. That being said, some questions remain unanswered. How did Elisa, who was obviously not in her right mind, end up in the hotel’s water tank, an area that is difficult to access? Here’s a news report describing the water tank area.

Shortly after the discovery of Elisa Lam’s body, a deadly outbreak of tuberculosis occurred in Skid Row, near Cecil Hotel. You probably won’t believe the name of the test kit used in these kinds of situations: LAM-ELISA. That is hardcore synchronicity.

The story of Elisa Lam is eerily similar to the 2005 horror movie Dark Water. Dahlia, the main protagonist of the movie moves into an apartment building with her young daughter Cecilia. Both of these names are relevant. Black Dahlia is the nickname given to Elizabeth Short, a woman who was the victim of a gruesome murder in 1947 – one that appeared to be particularly ritualistic. The case was never solved. According to LA Observed, it is rumored that Black Dahlia was at Cecil Hotel right before she lost her life.
