Mr. FRAZIER. Yes, sir. I had a spectrographer run an analysis of a portion of the hole which accounts for its being slightly enlarged at the present time. He took a sample of cloth and made an analysis of it. I don't know actually whether I am expected to give the results of his analysis or not. Mr. SPECTER. Yes; would you please, or let me ask you first of all, were those tests run by the Federal Bureau of Investigation in the regular course of its testing procedures? Mr. FRAZIER. Yes, sir; they were. Mr. SPECTER. And have those results been made available to you through the regular recordkeeping procedures of the FBI? Mr. FRAZIER. Yes, sir. Mr. SPECTER. Would you then please tell us what those tests disclose? Mr. FRAZIER. Traces of copper were found around the margins of the hole in the back of the coat, and as a control, a very small section under the collar was taken, and no copper being found there, it was concluded that the copper was foreign to the coat itself. Mr. SPECTER. Have you now described all of the characteristics of that hole, which you consider to be important for the Commission's consideration? Mr. FRAZIER. Yes, sir. Mr. SPECTER. Assuming that those clothes, that jacket, specifically, at this juncture, was worn by President Kennedy, and was in the same condition when that hole was made as it is now, and at the time when you made your examination, do you have a professional opinion as to what caused that hole in the back of the jacket? Mr. FRAZIER. Yes, sir; I would say that it was an entrance hole for a bullet. Mr. SPECTER. And what is the reason for that conclusion, please? Mr. FRAZIER. It has all the physical appearance characteristics which are considered when examining holes, such as its shape, its size, and in particular the fact that the fibers around the margins of the hole were all pushed inward where the cloth was torn by the object which passed through, and the fibers were unraveled as they were pushed inward, which is characteristic of a entrance-type bullet hole. Mr. SPECTER. Is the presence of the metallic substance relevant in your conclusion that it was a bullet hole? Mr. FRAZIER. Not necessarily. It is a factor which corroborates that opinion but even without it, it would still have been my opinion that it was a bullet entrance hole. Mr. SPECTER. Can you tell the size of the bullet from the hole in the jacket? Mr. FRAZIER. The hole in the jacket is approximately a quarter of an inch in diameter. Mr. SPECTER. Would that hole be consistent with a hole which would be caused by a 6.5 millimeter bullet? Mr. FRAZIER. Yes, sir; the actual bullet which makes a hole cannot be determined because the cloth in one instance may stretch more than it does in another instance causing either a larger or smaller hole even for the same caliber, but it is consistent for a bullet of 6.5 millimeters in diameter to make a hole of approximately this size.
