Re: fibers/ washing the mouth I was the hair and fiber expert at my old job, and I agree that you probably couldn't guess the type of clothing article from a single fiber. Maybe if you had a small piece of the cloth, to see pattern and weave, you could make a guess. But it would just be a guess, not really anything you'd want to be defending in court, unless you actually found the article it came from. And I've been to a lot of autopsies and they don't wash the mouth specifically but they'd wash blood off the face. How much water got in the mouth would depend on how neatly the deiner likes to work! Sorry I'm way late with this, just catching up.
