Can I please ask why you keep going on about photos at trial regarding Sheila's hand/s. You yourself were allowed a close-up view of Sheila's right hand on this forum. Your response was to launch in to attacks and rail against the person who allowed you to see the image. Why do you prefer to hang off the back of Hammersley's word - instead of just using your own eyes to view the image in question? 
Because my eyes tell me it's blood smearing, this is what the forum is about discussing evidence and dismissing evidence, if there is a way forward with your new evidence so be it, but what I've seen there isn't, don't put your theories on here if you don't want them to be discussed. Or do you want everyone to dismiss clear evidence, that without a shadow of doubt, backed up with numerous first hand account witnesses who clearly back my eyes against your eyes.
