As has been explained in chapter IV, the Commission determined that none of the warehouse employees who might have customarily handled these cartons left prints which could be identified.[C6-44] This was considered of some probative value in determining whether Oswald moved the cartons to the window. All but 1 of the 25 definitely identifiable prints were the prints of 2 persons--an FBI employee and a member of the Dallas Police Department who had handled the cartons during the course of the investigation.[C6-45] One identifiable palmprint was not identified.[C6-46] The presence on these cartons of unidentified prints, whether or not identifiable, does not appear to be unusual since these cartons contained commercial products which had been handled by many people throughout the normal course of manufacturing, warehousing, and shipping. Unlike other items of evidence such as, for example, a ransom note in a kidnaping, these cartons could contain the prints of many people having nothing to do with the assassination. Moreover, the FBI does not maintain a filing system for palmprints because, according to the supervisor of the Bureau’s latent fingerprint section, Sebastian F. Latona, the problems of classification make such a system impracticable.[C6-47] Finally, in considering the significance of the unidentified prints, the Commission gave weight to the opinion of Latona to the effect that people could handle these cartons without leaving prints which were capable of being developed.[C6-48] Though the fingerprints other than Oswald’s on the boxes thus provide no indication of the presence of an accomplice at the window, two Depository employees are known to have been present briefly on the sixth floor during the period between 11:45 a.m., when the floor-laying crew stopped for lunch, and the moment of the assassination. One of these was Charles Givens, a member of the floor-laying crew, who went down on the elevator with the others and then, returned to the sixth floor to get his jacket and cigarettes.[C6-49] He saw Oswald walking away from the southeast corner, but saw no one else on the sixth floor at that time. He then took one of the elevators back to the first floor at approximately 11:55 a.m.[C6-50]
