We've obviously had this exchange a dozen times or more. It seems very obvious to me that the blood stains on her night dress transferred from her wrist area of her right hand. Clearly Venizis realised this during his examination and prior to producing his final report.
He is very specific when he states that her palms and fingers were free from blood. He doesn't say that her hands were free from blood.
In order for your bible blood stain to be a Palm print left by Sheila, then her Palm and fingers could not be free from blood. Yet we know that they were.
Therefore, if the stain on the bible is a Palm print (which I very much doubt it to be) then it must belong to somebody other than Sheila.
That's a LOT of assumption H. We don't know that her hands were free from blood because that's not what he initially said. If her hands WERE free from blood why on earth write 'hands not contaminated
APART from blood'. And for him to suggest the stain on her nightdress came from her palm, he must have had reason for thinking that - if there was no blood on her palms, then he wouldn't have assumed it was a from her palm.
