Key and revealing information about the cover-up surfaced when the ARRB interviewed autopsy x-ray technician Jerrol Custer. Custer's testimony proves that the plotters were already exploring ways to produce altered skull x-rays the day after the autopsy.
Custer told the ARRB that the morning after the assassination, he was called into the radiology suite by Dr. John Ebersole, the autopsy radiologist, and was told to tape some metal fragments to skull bones and x-ray them. Custer x-rayed them with the same machine, at the same distance, that he used the night before during the autopsy. Custer stated that Ebersole said these x-rays would be used to make a bust of JFK. Custer added that Dr. Ebersole suggested that he “should forget” everything he was about to see:
A: The next morning I took them.
Q: And where did you take those X-rays?
A: In the main department, in a private room, with a portable X-ray unit.
Q: Was it the same x-ray unit that was used m to take the autopsy -
A: Yes, sir. The same distance.
Q: And what was the purpose of taking these x-rays?
A: I was told by Dr. Ebersole that they were to be taken to make measurements, to make a bust of President Kennedy.
Q: What did you do when you took the x-rays? What were the procedures? How did you go about taking them?
A: All I did was place the bone fragments on the film, and I made different exposures at different distances.
Q: Did Dr. Ebersole say anything to you about metal fragments?
A: He gave me three or four different metal fragments, varying in size. And he asked me to tape them to the bones. . . .
Q: Let me try asking you one question, just to make sure that the record is clear on this. Did Dr. Ebersole ask you to tape the metal fragments to the bone after he had returned from the White House? Are you able to say with certainty?
A: Absolutely. As soon as he walked in, that’s the first thing he said. “I want these bone fragments x-rayed with metal fragments taped”. . . .
Q: Is there any question in your mind whether you, in fact, taped metal fragments to the bones?
A: Absolutely no question at all in my mind. . . .
Q: Did Dr. Ebersole ever subsequently explain to you the purpose for taping metal fragments to the bones to be -
A: No, he didn’t. He just stated to me, when he brought the film -- the bone fragments and the metal fragments to me, that he had just come back from the White House after being debriefed.
Q: And what did he say about that debriefing?
A: WelI, he just said that he was debriefed by the Secret Service. And that was it.
High-ranking people had talked to him. And he suggested to me that everything that I see from now on, I should forget. (“Deposition of Jerrol Francis Custer,” ARRB, Transcript of Proceedings, October 28, 1997, pp. 143-146)
Obviously, taping bullet fragments to skull bones and then x-raying the bones had nothing to do with making a bust of JFK. Ultimately, the plotters opted not to use these x-rays because they realized that the x-rays could be altered via darkroom techniques that would be virtually impossible to detect at the time.
Scientific proof of the alteration was not discovered until Dr. David Mantik performed optical density (OD) measurements on the skull x-rays in the 1990s. Dr. Mantik discovered that the 6.5 mm object is not metallic and that the white patch in the lower rear parietal-occipital area is a physical impossibility for a human skull.
Dr. Mantik discovered that the 6.5 mm object was ghosted over a somewhat smaller genuine bullet fragment and a tiny bullet fragment. The largest of the two fragments is an irregular and jagged fragment measuring 2.0 mm at its narrowest point and 2.5 mm at its widest point, and measuring right around 6.3 mm in height. The tiny fragment is roughly circular and has a diameter of about 0.25 mm.
The density of these two genuine metal fragments is far less than the impossibly density of the 6.5 mm object as established by its OD measurements. The density of the two fragments is consistent with the density of metal fragments, whereas the 6.5 mm object's density is a physical impossibility if the object is metallic, proving that it is a ghosted image.
Dr. Mantik was even able to duplicate how the 6.5 mm object was added to the AP skull x-ray. The 6.5 mm object does not appear on the lateral skull x-rays, further absolute proof that the object is not metallic.
BTW, when Dr. Mantik read Custer’s ARRB testimony, he contacted Custer and was able to interview him at length. Custer reaffirmed his ARRB testimony in every detail.
It's truly amazing what you accept as proof. 30 year old recollections from an x-ray technician don't prove anything. Even if true, the conclusions you draw from his statement are highly illogical. You assume every unexplained event has sinister connotations.
