The 'wet' hair comes in as part of the cleansing ritual that many -maybe I, too, at one moment- went along with, but it was always quite obvious to me that her hair was dry. I haven't read any documents about her hair being examined minutely, but having put more than my fair share of hairs under a microscope, I find it interesting.
Re tampons, as in remove or leave in situ? As you say, we're all different.
Oh, pathologists examine every part of the body in a PM.
They also protect evidence by placing bags over the deceased person’s head, as they did Sheila’s before they removed her body.
In a post mortem they examine every single part of the body, both the outer and inner. Besides opening them up and looking at their organs, they examine the contents of their stomachs, bowels, vagina etc...
They also take samples from their mouths, teeth, nostrils, teeth, ears. Feet, toes, hands, underneath fingernails, and hair..
Hair is a vital part of a PM, as besides being able to establish where they’ve been, what diet/drugs they’ve taken by just one strand of hair, that depending on length can show all their movements over months, or even years, they also look for blood, human tissue, body fluids, and chemicals/fibres/sprays/pollution/smoke/dust/ flora/fibres/ particles from earth/woodlands/fields...everything
Hair is so revealing even if it’s been washed
But if it’s been washed prior to a person being killed at home, that washes away traces of outdoor elements.
In Sheila’s case it was proven that her hair had not been washed the day before she was murdered as she had particles amongst her hair that could have only been present by her being outside by a field. Maybe it was rapeseed spores...
It’s obviously invisible to the eye, just like cigarette smoke would be, but it clings to the hair and stays there until washed.
Sheila did not wash her hair that evening, and that’s a fact, and I shall find the document that states that.
Re: the Tampax. Yes, we’re all different, but I personally (unless having a heavy blood flow mid cycle) would always remove the Tampax prior to bathing/showering, and then insert a new one, I just feel it’s fresher somehow.
