_Examination of clothing._--The clothing worn by President Kennedy on November 22 had holes and tears which showed that a missile entered the back of his clothing in the vicinity of his lower neck and exited through the front of his shirt immediately behind his tie, nicking the knot of his tie in its forward flight.[C3-193] Although the caliber of the bullet could not be determined and some of the clothing items precluded a positive determination that some tears were made by a bullet, all the defects could have been caused by a 6.5-millimeter bullet entering the back of the President’s lower neck and exiting in the area of the knot of his tie.[C3-194] An examination of the suit jacket worn by the President by FBI Agent Frazier revealed a roughly circular hole approximately one-fourth of an inch in diameter on the rear of the coat, 5⅜ inches below the top of the collar and 1¾ inches to the right of the center back seam of the coat.[C3-195] The hole was visible on the upper rear of the coat slightly to the right of center. Traces of copper were found in the margins of the hole and the cloth fibers around the margins were pushed inward.[C3-196] Those characteristics established that the hole was caused by an entering bullet.[C3-197] Although the precise size of the bullet could not be determined from the hole, it was consistent with having been made by a 6.5-millimeter bullet.[C3-198] The shirt worn by the President contained a hole on the back side 5¾ inches below the top of the collar and 1⅛ inches to the right of the middle of the back of the shirt.[C3-199] The hole on the rear of the shirt was approximately circular in shape and about one-fourth of an inch in diameter, with the fibers pressed inward.[C3-200] These factors established it as a bullet entrance hole.[C3-201] The relative position of the hole in the back of the suit jacket to the hole in the back of the shirt indicated that both were caused by the same penetrating missile.[C3-202] On the front of the shirt, examination revealed a hole seven-eighths of an inch below the collar button and a similar opening seven-eighths of an inch below the buttonhole. These two holes fell into alinement on overlapping positions when the shirt was buttoned.[C3-203] Each hole was a vertical, ragged slit approximately one-half of an inch in height, with the cloth fibers protruding outward. Although the characteristics of the slit established that the missile had exited to the front, the irregular nature of the slit precluded a positive determination that it was a bullet hole.[C3-204] However, the hole could have been caused by a round bullet although the characteristics were not sufficiently clear to enable the examining expert to render a conclusive opinion.[C3-205]
