To me, it just seems like an area on of the nightdress that is not bloodstained. Hence the entire thing is over shadowed in other photos.
LOL WALOB
The object shines when a flash photograph is taken from the side or rear of SC but does not appear visible in photos taken from her feet up towards the face. That is why in some pictures it just appears as a black blob as there is no reflected light.
Now, with reference to your tedious and juvenile references to the discovery of Sheila's 28 wounds in 2016, it was originally planned to refer this to the CCRC then, which could have resulted in his release in 2017. It was subsequently Jeremy's decision to delay referring to the CCRC in 2016 as so much new evidence was being uncovered and he wanted it all considered at once.
Those who have seen the evidence of the 70 unreported wounds to the adults all agree that it is sufficient on its own to secure his release, as will be seen in due course.
Maybe you could grow up and cease making reference to my confidence that he could be released in 2017? It would be an adult way of going forward. Or, does it give your kiddie ego a thrill every time you mention it?
