Okay. I may or may not cross a line here, so if I do then I am sure Summer Breeze or Bessie will let me know.
This case has little to go on. What we do have is a lot of "way in left field" theories, and a few sound ones. The video is the only sure thing we have access to (ad nauseum) aside from pictures. Whether the mental health professionals are stating that she is showing signs of a mental break or not, they are putting their opinion for you to take. By blindly looking past it, or refuting it based on a criteria list makes absolutely no sense to me.
Now it could very well be murder. Doesn't mean that she wasn't having issues in that video. <modnsip>
As for bias, if that is what they are seeing, then why would it be? I have posted my own opinions on matters based on professional experience, only to have people with no experience try to tell me otherwise.
Edit: And what are you leaning to in terms of theory?
<modnsip>
But since you brought it up, I'll give you my take on her analysis:
IMHO her behaviour is that of someone experiencing psychosis.
1. The "holiday" alone with no fixed plans
No fixed plans? She planned specific dates for different cities. As for local plans, we don't know about that, but she went to touristy places like the San Diego Zoo and Conan O'Brien show. Also, many people don't have fixed plans when they travel, especially when you are young.
2. History of depression - more severe mental illnesses like Schizophrenia can often first present as depression. The stress of school could have brought this on.
This doesn't mean much. Yes, Schizophrenia can often first present itself as depression, but that doesn't mean that people who are depressed are likely to develop Schizophrenia. Even if 100% of people with Schizophrenia patients had depression previously, it wouldn't tell us if 0.00001% of people who are depressed develop Schizophrenia. "The stress of school" is pure speculation.
3. Her behaviour in the elevator looks to me like someone experiencing paranoid ideation and possibly command hallucinations (voices telling her to do something like press all the buttons). The hiding and peeking out the door is a response to the paranoid thoughts that "someone is out to get her"
4. The wild gesticulating in the corridor to seemingly nobody is a response to internal stimuli - (voices in her head).
These are pretty much the same point. Her behavior is unknown at this point. You can say that people who are experiencing psychosis often display this behavior, but that doesn't mean people who are normal don't exhibit this behavior under certain conditions. Again, why did she wait for the elevator to close? If she was intent on going down in the video, why go up to the roof?
It's more likely that she was peeking out the door to see if anyone was holding it open. You can even argue that hiding in the corner may not have been hiding at all, that it was to get a good angle to see if someone was pressing the button outside.
5. She probably hid in the water tank to escape her perceived threat. People experiencing psychosis do not make rational plans.
Speculation. Also, "probably" is a strong word. Why didn't she hide in her room? Her closet? In the bathroom? Go to the lobby? A water tank on the roof is not something people, sane or insane, would think of. How did she even know they were accessible? If the water tank was two feet away from the elevator, it would be more plausible.
We're talking about probabilities here. Almost everything is possible, but her going crazy and putting herself in a water tank is highly unlikely, without further evidence. So is your theory on "sex games gone wrong". Now, if she was experiencing psychosis, it would be more plausible that someone took advantage of her in her mental state, than to assume that her death was a direct result.
I already posted one theory on how her behavior in the elevator could be explained, at the beginning of this thread. Feel free to rip it apart, I actually would encourage it.
