The images in the pdf have just been manipulated, there appears to be a white dot on one area of blood staining that people are thinking is skin gouged up, but it is just where the image has been lightened and become pixilated.
Seeing the image below and wider angle images in the photo library we can see that it is simply a continuation of blood staining rather than wounds.
Nice try guys. 

Is this the 'non manipulated' photo?
Even if it is - I'm sorry - but what I see are a full crescent gouge with a stain underneath it and a partial crescent gouge with a stain underneath it. In the images put up by Bill - it is possible to see that the partical cresecent gouge is actually separated. The stains underneath are still quite possibly grazes even in this image.
There is also still a distinctive 'nick' on the inside of Sheila's forefinger - above where the side of the hand eventually meets the thumb.
