What the coroner (a bureaucrat in most places) states as the official cause of death? In a foreign country with surely great medical practices and transparency like Turkey no less? Sure. Lets take their word for it.
I doubt we will find out more about what happened in this case. If the family is accepting the official theory, perhaps also after getting a phone call, then just let it be.
Personally I think it is suspicious because I don't think a successful career person in her position (based upon a psychological profile), even if they were depressed, would have done this in such a conspicuous public place all on a whim like that. They would tend to choose a more discrete location, somewhere more private like a hotel or at home or out in nature, to do it (they tend to want to retain some dignity and self-respect, hence the desire for somewhere private and not public). Anyway, I'm sure if there is something going on and she is in a certain line of business, then the right kind of investigation will be happening behind the scenes - just that nobody will be reporting about it to the news anymore and they will get to the bottom of it.
