Elisa Lam's disappearance in early 2013 quickly became a media sensation, as the Canadian student had seemingly vanished without a trace from her room in the Cecil Hotel in Los Angeles.
After her body was found in one of the hotel's water tanks several weeks later, following complaints from guests of low water pressure and foul-tasting water, investigators and Lam's family were still left with more questions than answers.
Lam's disappearance and tragic death - which remain a cultural fixation to this day - are the focus of a new series on Netflix called "Crime Scene: The Vanishing at the Cecil Hotel."
In addition to taking a deep dive into the 21-year-old's final days, the show also sheds light on the dark and violent history of the Cecil, where many people have died by suicide, and where serial killers such as Richard Ramirez and Jack Unterweger have stayed.
"Crime Scene" does end up concluding that Lam's death was an unfortunate accident - not foul play or the effects of paranormal activity, as some believe. However, the show, which premiered Wednesday on Netflix, still leaves some important questions answered.
Here are seven questions we still have about Lam's death after watching "Crime Scene: The Vanishing at the Cecil Hotel."
