Well, I hate to be spoilsport, but with all due respects, I'd disagree. Much as I admire your skills with the pics, Makara, as I posted previously, that little discolouration on his left cheek looks like a thing called a lentigo, and the mark on his forehead (in fact all the marks on his forehead) look like solar keratoses.
The fact that they were there in previous photos (eg carrying the laundry basket) and still there at the funeral, would be consistent with that, too. Acute traumatic marks, like scratches, bruises, etc, would be well gone by the time of the funeral.
I really think people are reading things into these photos that aren't there - at least not to my clinical eye they're not.
One thing that does show up in your Photoshop work, though, in the shot with increased saturation, is that it is NOT a big curved scratch on the left side of his face in the funeral shot. You can quite clearly see the skin lines, and they have not been breached. Scars that run ACROSS skin lines tend to be fairly obvious. One reason that surgeons try to put incisions along skin lines where possible.
