In 1967 the autopsy pathologists (Humes, Boswell, and Finck), the acting chief of radiology (Ebersole) and one of the autopsy photographers (Stringer) viewed the autopsy photographs and/or X-rays and confirmed the photos and X-rays were accurate in the portrayal of the wounds of the President.
The Clark Panel studied the autopsy X-rays and photos and concluded that the head was struck once from above and behind.
The Rockefeller Commission studied the autopsy X-rays and photos and concluded that the head was struck once from behind.
The HSCA forensic panel studied the autopsy X-rays and photos (and interviewed the Kennedy autopsy personnel in order to verify the validity of the photos and X-rays) and concluded that the head was struck from behind.
In 1964 the WC said JFK was struck in the skull slightly above and slightly to the right of the
external occipital proburence (EOP).
When critics noted the EOP wound location didn't work with a TSBD 6th floor SE corner shooter the Clark Panel was formed and conveniently moved the wound 4 inches higher on the skull to conform with the official LN narrative.
The Panel said the trail of metal particles high in JFK's skull, visible in the x-ray below, show the wound location.
The autopsy doctors noted that photo's they had made of the inside and outside of the EOP wound in the skull were no longer among the autopsy materials in the archive.
Without those photo's the Rockefeller Commission and HSCA had no choice but to agree with the Clark Panel's wound location.
The autopsy doctors stood by their original EOP wound conclusions until death.
IMO the Clark Panel located a second wound in JFK's skull.
