There are plenty of scenarios that could play off of her being manic/schizo and just being a nut case cause of withdrawals and the like. Her toxicology results showed she had no drugs in her system, despite being prescribed to stay mentally stable. Her roomates said she was acting strange, again missed her meds. The days leading to her death she's just mentally loopy/unstable. Having meltdowns. Somehow she ended up at the top of the Cecil, the door leading into the tank I remember reading wasn't heavy enough for someone to open. Very plausible she just went in because. Being mentally unstable, people do some "dafuq?" Type stuff. My belief, when she got inside the tank, she opened the top enough to get in, but just enough for gravity to hinge the top back to closure. Given her manic state. She stripped down and boom. She died over time. I'd love to believe something more sinister was afoot, given the hotel's history. But this is just a sad case of an unstable youngster
