Then it was misinformation given on Fox News because that was how they reported it.
Hmmm. I can’t comment on that, because I did not see that, or at least I do not remember seeing it on Fox.
Just going strictly on that story I linked-
““Sources said the medical examiner found Gray’s catastrophic injury was caused when he slammed into the back of the police transport van, apparently breaking his neck; a head injury he sustained matches a bolt in the back of the van.”
It seems like the examiner is saying that hard contact with the back of the van caused the catastrophic injury, and that the bolt related injury illustrates, demonstrates or otherwise proves that at some point his head contacted the back of the van containing that bolt with sufficient force to leave the mark of that bolt.
Looking at those pictures posted in this thread, I do not see a bolt that is large enough or protruding to such an extent that contacting it would cause mortal injury. But I do see what looks like rivets or something like that on the back door that could potentially leave an mark if one hit one hard enough.
