176 Assassinatlon of President John F. Kennedy a white man from a window on the sixth floor of the building in which Oswald was employed. This witness later selected Oswald in a line- up as the person who resembled the individual he observed fire the rifle from the window. The witness could not make a positive identification. Mrs. Earlene Roberts, 1026 North Beckley Street in Dallas, stated Oswald, using the name of 0. H. Lee, had lived at her residence since October 14, 1963, and at about 1:00 p.m., November 22, 1963, came to her residence, picked up a jacket and left hurriedly. A 6.5 caliber Italian carbine rifle with a four-power scope was found on the sixth floor of the building in which Oswald was employed and from which the shots at the President were fired. Investigation by our Chicago Office has revealed that a weapon of this description and identical serial number was sold to one A. Hidell, Post Office Box 2915, Dallas, Texas, on March 28, 1963, for $21. 45. This Post Office Box at that time was rented by Mrs. Lee H. Oswald, believed to be the mother of suspect. Oswald, at the time of his arrest, had in his possession a Selective Service card in the name of Alex Hidell. The recovered rifle as well as the .38 caliber revolver taken from Oswald, were immediately brought to the FBI Laboratory for examination. It was determined that a bullet found on one of the stretchers at the hospital following the admittance of President Kennedy had been fired from the rifle referred to above. Examination also identified two bullet fragments found in the Presidential car as having been fired from this same weapon. Other examinations in the FBI Laboratory are continuing. A brown paper bag possibly used to carry the rifle was found near the window on the sixth floor of the building from which the shots were fired. A latent fingerprint developed on this bag by the FBI Identification Division was identified with the left index finger impression of Lee Harvey Oswald.
