Yes! I have some graphic design experience and I tried something and it worked. The photo online is very pale and washed out but the techniques i used increase the contrast and if you exaggerate certain colour techniques what will happen is this - it can't create marks that aren't there but it will show marks that are there and it does show a scar very close to the right eye - like a scratch very near the eye that has become a welt - perhaps what would happen if someone was absolutely clawing?
The hand is also interesting, yes there are small scratches showing above the cuff, but also the hand has blotchy red marks on it near the knuckles and fairly large ones above the wrist - as if the top of his hand has been not only scratched but perhaps held onto and pulled - but he has pulled harder and the hands pulling on his have lost their grip. Or there may be another explanation depending on what he actually did. But I am definitely thinking there has been some sort of mild trauma to the hand and perhaps more serious scratches elsewhere from what others are saying, plus the disguised welt on his face.
I agree, I think we are very close to an arrest, and maybe all of us here are closer to putting it together as a whole - maybe with some gaps, but from everything we have discussed over this last 10 days or so, i believe many of us could put together something quite close to what actually occurred, with of course missing bits due to our own lack of information. I feel sad for everyone involved, mainly for Allison, the girls and her parents of course. But I also look at him and I see him as pathetic - however that is being kind I guess. If he did it, sadly, he is evil.
