I'm on the fence. Having the experience of sharing a home with a schizophrenic woman, I gained an incredible amount of insight. The behavior due to their mental illness is bizarre to watch with your own eyes. The woman I shared a home with was my roommate's adult daughter. She would have auditory and visual hallucinations that she would interact with all day. She was incredibly paranoid, as well. If Elisa was suffering from mental illness, I would suspect that she either harmed herself unintentionally, or that someone may have noticed her vulnerability and taken advantage of it. The second possibility makes me feel just as equally that her death could have been a murder, which used her possible mental illness as a cover up. This would make sense if someone saw her as vulnerable or an easy target, and it ties both of the theories together. We have no proof that Elisa did this to herself and I can't believe that she did without significant evidence. Yes, her behavior may have been unusual, but that could have been what caught the attention of the perpetrator, if indeed there was a perpetrator.
What I do know is that Elisa was afraid. Maybe of a person, and maybe of her own mind. It hurts my heart and I wish someone could have given her the help she deserved, regardless of what type of help that may be.
May Elisa finally rest in peace.
