For further evidence that reel 61 was shot before reel 59 noticed the splatter on the wall behind the head.

I didn't save a lot of frames of this, but you will need to look it up on the autopsy movie video yourself anyway so that you know I didn't "doctor" the pictures.

(This frame from reel 62, the eye covering removal sequence.)
 

The splatter isn't there at the beginning of the movie as in this still from reel #53..
 

 The first time we see the splatter is on  reel 59.
 

 And the splatter is missing from reel 61.
 

  From reel 62 on till the end of the footage the splatter is seen consistently in the movie.
 

  As you can see from this example, all of the evidence for the reels being out of order is not on the body. The splatters follow the same sequence of disappearing and reappearing as the blood drips.
   And it doesn't seem likely that the doctors wiped off the wall, then managed to splatter it back in the same place later. Unless they were staging a scene, of course.
