The HSCA Cranial 'Exit' Wound

The HSCA Forensic Pathology Panel determined a (cranial)

exit wound to JFK's head. The diagram opposite shows where they found it to be.

Dale Myers "Secrets of a Homicide"

Myers, a writer supporting the 'lone nut' theory (as I do) found an obvious problem with the HSCA trajectory.


A trajectory analysis of JFK's inshoot/outshoot head wounds,
shows an inconsistency with the HSCA trajectory conclusions.

The Zapruder film shows JFK receiving his head wound at frame 313. Using medical data from the House Select Committee on Assassination's (HSCA) Forensic Pathology Panel and Zapruder frame 312 (JFK's last known position before impact), a trajectory was plotted to determine the source of the shot.

The HSCA Forensic Pathology Panel located the entrance wound on the back of the head about 10 cm above the external occipital protuberance, and 1.8 cm to the right of the midline. An exit wound was located near the right temple 11 cm in front of, and 1 cm below the entrance wound, about 5.5 cm right of the midline. These points were located on a computer model representing JFK's skull.
The two points were connected with a straight line and projected rearward 200 feet to represent the trajectory of a missile passing through these two points. The trajectory track was then applied to the recreation at the equivalent of Zapruder frame 312.


The results [left] show a trajectory track (blue line) that intersects the western face of the Dal-Tex Building, 33.5 feet north of the south face, and 124.6 feet above the roofline.
This finding is at odds with the HSCA Photographic Panel which calculated a trajectory that intersected the Texas School Book Depository at a point 11 feet west of the southeast corner of the building and 15 feet above the sixth floor window sill. (6HSCA41)
The discrepancy is probably due to a calibration photograph used by the HSCA to position JFK's head at Zapruder frame 312. A comparison of this photo with Z312 and the corresponding computer frame reveals apparent rotational differences.


As Myers discovered, something is very wrong somewhere.

Another Small Problem

The HSCA exit wound is found, on analysis *, to emerge through the anterior section of the large flap visible on the 'back of the head' autopsy photographs.

Clearly this did not happen - as there is ( it is hardly necessary to point out) no such wound there. (See photo at right).

How The HSCA Forensic Pathology Panel Arrived At Their 'Exit' Location

The Forensic Pathology Panel (FPP) used two pieces of evidence.

1) The 'scalp reflected' autopsy photographs. (below left) &

2) An x-ray of the largest of the 3 'late-arriving' bone fragments - 3 fragments of bone brought to the morgue during the autopsy. (below, right)

Dr. Larry Angel

A forensic anthropologist (Dr. Larry Angel) was called in to help with the evaluation of the autopsy materials. He oriented the above autopsy photograph as below :

He also declared that the large fragment of bone

(arrowed above) was 'clearly frontal'.

The FPP somewhat covertly rejected both of these conclusions, though they called in no other expert with any other opinion to contradict Dr. Angel. I believe this was done in order to manufacture one 'whole' piece of 'exit' evidence out of two distinctly less than 'half' such.
