It has been said that he requested his asthma inhaler and medical assistance several times on the way to the station. It’s not possible to speak with a crushed larynx.

No, its not. Therefore if it was crushed, he didn't speak. And if his neck was broken and his heart stopped, that would also prevent him from speaking. So someone is lying big time.

FWIW I don't think he was propped up when he got into the van so I don't think he was paralyzed at that time.

Here is the video that shot was taken from.
