Once again , how did that small hole in the neck , which had a tracheostomy made over it in Dallas , turn into a very wide gash once JFK's body was at Bethesda and Parkland only saw a small hole in the front of the neck and a large blown out hole in the Occipital area which was in the rear of the head . No one else saw any other wounds on the presidents head . How did the top of JFK's head and the right side of his head become so injured after JFK's body left Dallas ? If the Parkland Drs. had seen the head injuries that Bethesda saw , then the Parkland Drs. would have known that there was no way that JFK could have survived . There is no mystery about what happened to JFK , especially when it comes to the wounds .
