Sheila did - Venezis said so. I don't see a U stain on the carpet.
Vanezis didn't say anything about the inside of her palms being bloody, he said they were not bloody. The police said they were not bloody. There were photos taken of her hands at the autopsy which show the inside of her hands were not bloody. The only blood visible in any photos and/or mentioned by Vanezis or others who saw her hands was noted as being on her outer wrist/outerpalm area.
The Bible was tested for prints and NONE were found in blood. The experts who actually looked at this blood up close and personal to look for prints decided there were no prints of any kind in blood they assessed it was made by the carpet which happened to have blood underneath this very area of the Bible. You don't have all the photos they did nor did you see it up close like they did.
Your speculation is worse than Sutherst's.
