Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

This guy in the white shirt, the ambulance assistant, is the one who disappears.  This is at Parkland, but we don't see him again after this. It's like he got bumped. His name was Harold Wayne Wolfe. 

Here is the driver Michael Herdin leaving the hospital, removing the sheet from the gurney. But, we don't see Harold. He has already vanished.

So, at this point, Harold was already removed from the team.

Here's a related image. I don't know who the man is in the sunglasses. I presume he was FBI or SS. There is something white over Oswald. If it's supposed to be covering his wound, it's on the wrong side. 

And here is another image very similar to the first.

Hardin looks very mobilized there, but it is very strange that he would be pushing on Oswald's arm and expecting it to transfer to the gurney. I can't imagine the point of that except to have Oswald's arm raised. And there his fist really looks tightly closed. There could be a little curl in the fingers from the spring tension of the tendons but nothing like that. That you have to "do." 

I'm surprised that the hospital staff didn't come racing out with their own gurney, that is, if they were forewarned. And I presume they were forewarned.
