As Jackie & Robert accompany the bronze casket to Bethesda, Hubert Clark and the remaining Honor Guard members shadow this grey ambulance to Bethesda by helicopter. The Honor Guard arrived moments earlier than the grey ambulance to assist removing the casket. At this time the Honor Guard was placed in the bed of a pick-up truck and followed the grey ambulance to the loading dock. However, the grey ambulance turned off their lights and tried to 'lose' the accompanying Honor Guard. According to Clark, they circled the Bethesda facility three times when they finally saw the grey ambulance at the loading dock.
While standing guard outside the morgue, Hubert Clark observed JFK's body on the autopsy table. He noticed his head being supported by an object called a 'Chock Block.' When shown the official autopsy photos in 2015, both Hubert Clark and morgue technician, Jim Jenkins, said this was not what the President looked like. Also, Jim Jenkins said, 'Bethesda didn't even have this (Chock Block) type of equipment in 1963.' This photo was taken somewhere besides Bethesda Naval Hospital.
In this image you can see the neck wound is completely different than what the Doctors at Parkland Hospital described. They said the tracheostomy incision was made through the 'entrance wound' in the neck. Also in this image, you can see JFK's (L in image) forehead area and what appears to be a small bullet entrance wound near hairline.
