The Commission has weighed the visual recollection of Frazier and Mrs. Randle against the evidence here presented that the bag Oswald carried contained the assassination weapon and has concluded that Frazier and Randle are mistaken as to the length of the bag. Mrs. Randle saw the bag fleetingly and her first remembrance is that it was held in Oswald’s right hand “and it almost touched the ground as he carried it.”[C4-171] Frazier’s view of the bag was from the rear. He continually advised that he was not paying close attention.[C4-172] For example, he said, * * * I didn’t pay too much attention the way he was walking because I was walking along there looking at the railroad cars and watching the men on the diesel switch them cars and I didn’t pay too much attention on how he carried the package at all.[C4-173] Frazier could easily have been mistaken when he stated that Oswald held the bottom of the bag cupped in his hand with the upper end tucked into his armpit. Location of Bag A handmade bag of wrapping paper and tape[C4-174] was found in the southeast corner of the sixth floor alongside the window from which the shots were fired.[C4-175] (See Commission Exhibit No. 2707, p. 142.) It was not a standard type bag which could be obtained in a store and it was presumably made for a particular purpose. It was the appropriate size to contain, in disassembled form, Oswald’s Mannlicher-Carcano rifle, serial No. C2766, which was also found on the sixth floor.[C4-176] Three cartons had been placed at the window apparently to act as a gun rest and a fourth carton was placed behind those at the window.[C4-177] (See Commission Exhibit No. 1301, p. 138.) A person seated on the fourth carton could assemble the rifle without being seen from the rest of the sixth floor because the cartons stacked around the southeast corner would shield him.[C4-178] (See Commission Exhibit No. 723, p. 80.) The presence of the bag in this corner is cogent evidence that it was used as the container for the rifle. At the time the bag was found, Lieutenant Day of the Dallas police wrote on it, “Found next to the sixth floor window gun fired from. May have been used to carry gun. Lt. J. C. Day.”[C4-179] Scientific Evidence Linking Rifle and Oswald to Paper Bag
