The Walker Bullet
On April 10, 1963, a bullet was recovered from General Walker’s home, following an attempt on his life.[A10-98] The bullet, which was severely mutilated, weighed 148.25 grains.[A10-99] This bullet had the rifling characteristics of the C2766 rifle and all its remaining physical characteristics were the same as the Western 6.5 millimeter Mannlicher-Carcano bullet. However, while the bullet could have been fired from the C2766 rifle, it was severely mutilated and in Frazier’s opinion could not be identified as having been fired or not fired from that rifle.[A10-100] Nicol agreed that a positive identification could not be made, but concluded there was “a fair probability” that the bullet had been fired from the same rifle as the test bullets.[A10-101]
FINGERPRINTS AND PALMPRINTS
Two experts gave testimony concerning fingerprints and palmprints: Sebestian Latona[A10-102] and Arthur Mandella.[A10-103] Latona is the supervisor of the Latent Fingerprint Section of the Identification Division of the FBI. He has been with that Division over 32 years, having begun as a student fingerprint classifier and worked up to his present position. Mandella is a detective and fingerprint instructor with the police department of the city of New York. He has been in the fingerprint field for 19 years. Both have made a vast number of fingerprint examinations and have testified in Federal, State, and military courts.[A10-104] Their conclusions were identical, except as noted.
General Principles[A10-105]
Fingerprints and palmprints are made by the ridges which cover the surface of the fingers and palms. These ridges first appear 2 or 3 months before birth, and remain unchanged until death. Commission Exhibit No. 634-A ([p. 564]) illustrates several common characteristics or “points” formed by the ridges; a clear fingerprint impression will contain anywhere from 85 to 125 such points. While many of the common points appear in almost every print, no two prints have the same points in the same relationship to each other.
A print taken by a law-enforcement agency is known as an “inked print,” and is carefully taken so that all the characteristics of the print are reproduced on the fingerprint card; a print which is left accidentally, such as a print left at the scene of a crime, is known as a latent print. To make an identification of a latent print, the expert compares the points in the latent print with the points in an inked print. If a point appearing in a latent print does not appear in the inked print, or vice versa, the expert concludes that the two prints were not made by the same finger or palm. An identification is made only if there are no inconsistencies between the inked and latent prints, and the points of similarity and their relative positions are sufficiently distinctive, and sufficient in number, to satisfy the expert that an identity exists.[A10-106]
There is some disagreement concerning whether a minimum number of points is necessary for an identification. Some foreign law-enforcement agencies require a minimum number of 16 points. However, in the United States, in which there has been a great deal of experience with fingerprints, expert opinion holds there is no minimum number of points, and that each print must be evaluated on its own merits.[A10-107]
Palmprints are as distinctive as fingerprints, but are not as popularly known. Possibly this is because law enforcement agencies usually record only fingerprints for their identification files, since fingerprints can be much more readily classified and filed than palmprints. Also, latent fingerprint impressions are probably more common than latent palmprint impressions, because persons generally touch objects with their fingers rather than their palms. However, palmprints will frequently be found on heavy objects, since the palms as well as the fingers are employed in handling such objects.[A10-108]
