7 questions we still have about Elisa Lam's death after watching 'Crime Scene: The Vanishing at the Cecil Hotel'

Lam's body was found in one of the hotel's four water tanks by a maintenance worker responding to complaints about the water by hotel guests.

According to the series, she was found floating face up and was completely naked, with her clothes and room key at the bottom of the tank.

Hotel staff said was difficult to gain access to any of the tanks, and that going inside would require moving a 20 pound lid off the tank's opening. The lid was reportedly open when Lam's body was found — suggesting that she opened the tank and jumped in herself.

But the question that continues to puzzle investigators, staff, Lam's family, and followers of the case is: Why did Lam go into the tank in the first place? And how exactly did she end up on the roof?

Lam's family revealed to investigators that she'd been diagnosed with depression and bipolar disorder, which eventually led them to theorize that the student had been experiencing a manic episode, potentially with auditory hallucinations and paranoia, at the time of her death.

That's only a theory, though, and without any further evidence, the true reason why Lam decided to go into the tank remains a mystery.

According to toxicology reports conducted after Lam's body was found, traces of prescription psychiatric drugs, including antidepressant Wellbutrin, mood stabilizer Lamictal, and antipsychotic Seroquel were found in her system.

These drugs are usually prescribed to patients with bipolar disorder and depression, both of which Lam had. However, the levels of the drugs in her system, coupled with the remaining doses later found in her possessions, revealed that Lam was potentially skipping doses or otherwise taking her medications incorrectly.

On her Tumblr, Lam had written frequently about being frustrated by her mental illness, as well as her desire to travel and live a fulfilling life. Some web sleuths, as well as a few investigators, have suggested that perhaps Lam started skipping doses during her trip to Los Angeles in order to feel more "normal" — ultimately leading to a manic, paranoid episode that ended with her accidentally drowning.

Unfortunately, the show isn't able to do much other than present theories as to why Lam wasn't taking her medication correctly, leaving viewers to draw their own conclusions.

Another question that baffled some followers of the case is why the police didn't find her body at first — even though they searched all parts of the hotel, including the roof, extensively, and with the help of tracking dogs.

Law enforcement featured on the show don't really give a clear-cut answer as to why they missed Lam's body during their initial search of the hotel, nor why they didn't think to check the water tanks.

And while police have said that it was merely an oversight, plenty of web sleuths interviewed on "Crime Scene" have suggested that law enforcement were potentially covering for one of their own, and that Lam's death was, in fact, a homicide.

Ultimately, the evidence still points to Lam's death being an accidental drowning, but it's still unclear as to how a team of police officers and highly-trained canines could miss a body.

One of the more disturbing things to come out of the investigation was a two-minute long clip of Lam in the Cecil Hotel's elevator — the last time she was seen on surveillance footage before her body was discovered.

In the video, which has since been viewed millions of times on YouTube, Lam steps into the elevator and pushes an entire row of buttons before beginning to act erratically.

Lam steps out of the car numerous times, appearing as though she was checking to see if she'd been followed, before walking back in. During one particularly chilling moment, she appears to be talking to someone off camera, waving her hands in a bizarre pattern before jumping back into the elevator and hiding herself in a corner.

The clip concludes with Lam wandering out of the car.

Following the discovery of her body, numerous people wondered if Lam was actually alone in that video — or if there was someone offscreen who was talking to or threatening her.

Some sleuths have pointed to a suspicious shadow in the corner of the video as evidence that there was another person there with Lam, but no one has been able to definitively prove it one way or another.

Another theory tied to the chilling elevator footage of Lam was that the video was edited, either by someone in the hotel, or perhaps by law enforcement, who were covering for a fellow officer or someone powerful.

Web sleuths pointed to the video's grainy timestamp (that doesn't appear to be accurately measuring the seconds), and several glitchy cuts in the clip as evidence of tampering.

In "Crime Scene," however, the former manager for the hotel denies that the video was edited by someone at the Cecil, and law enforcement don't appear to believe that theory either.

The quality of the video is certainly worth noting, but it's hard to tell either way whether it was simply a subpar camera or actual evidence of editing. And if the clip was, in fact, edited, then the question remains: Who edited it and why?

It's revealed in "Crime Scene" that prior to her disappearance and death, Lam was removed from her shared room in the hotel after her roommates complained of her odd behavior.

The show doesn't go into exact details, but Lam was reportedly leaving cryptic notes for her roommates, and was even escorted off a taping of a live TV show in Burbank for writing a rambling letter to the host.

Many have suggested that these strange actions were the sign of a manic episode and the result of Lam not taking her medications properly.

But aside from moving her into a private room, the Cecil is portrayed as not doing much else to make sure Lam was OK.

In the show, the hotel's former manager, Amy Price, explains that bizarre behavior was par for the course at the hotel, which has housed drug addicts, mentally ill people, and sex workers throughout the years. Price essentially tells producers that while Lam's behavior was odd, it didn't merit any special attention.

As a viewer, though, it's hard not to wonder why the hotel didn't do more to help and whether or not assisting Lam could have prevented her death.

Despite the fact that she died over seven years ago, Lam's tragic end has continued to garner the attention of online conspiracy theorists and casual true crime junkies alike.

A viral TikTok in December even brought the case to the attention of Gen Z, who quickly began sharing their own thoughts on the tragedy.

Even though law enforcement ultimately ruled Lam's death an accidental drowning, plenty of people still have theories as to how she died or who could have killed her.

Some of these theories, including one involving a death metal musician named Morbid, do more harm than good as "Crime Scene" shows.

After watching the series, it's pretty evident that Lam's death was a tragic but genuine accident.

Regardless of the coroner's ruling, or of new evidence that comes to light, however, it's clear that some people refuse to believe this — and are determined to discover the "truth" about Lam's death.
