Would it be okay with you if I quoted someone who is in higher authority than the police chief? Apparently, you haven't followed this very close.
Any direct quote that proves your point is fine. The floor is yours.
Don't worry, I will find it for you. It should be obvious, however, that they didn't perform an autopsy on her as required by law. That, by itself, means it was not necessary according to the government. Of course, you could show me the law that Pakistan does not require an autopsy in a suspicious death in the meantime? That way we both get to work : )
