There are now multiple different videos/images of the shooter dead on a roof of a one story building outside of the crowd, of his body being retrieved, of a man saying he pointed the guy out to police before the shooter shot, and that counter sniper fire ‘blew his head off’.
The shooting angle seems to be relatively flat, either grazing the top of his right ear or possibly taking a small chunk of it.
At least two people in the crowd behind Trump were hit, one is dead.
From Kyle Kulinsky’s clip compilation on Youtube an off duty paramedic had his shirt covered in blood and described doing chest compressions on a man with a head wound including exposed gray matter.
Check his YT for the interview of the guy who saw the shooter on the roof as well.
