Mooney's discovery intensified the search for additional evidence on the sixth floor, and at 1:22 p.m. approximately 10 minutes after the cartridge cases were found, Deputy Sheriff Eugene Boone turned his flashlight in the direction of two rows of boxes in the northwest corner near the staircase. Stuffed between the two rows was a bolt-action rifle with a telescopic sight. The rifle was not touched until it could be photographed. When Lt. J. O. Day of the police identification bureau decided that the wooden stock and the metal knob at the end of the bolt contained no prints, he held the rifle by the stock while Captain Fritz ejected a live shell by operating the bolt. Lieutenant Day promptly noted that stamped on the rifle itself was the serial number "C2766" as well as the markings "1940" "MADE ITALY" and "CAL. 6.5." The rifle was about 40 inches long and when disassembled it could fit into a handmade paper sack which after the assassination, was found in the southeast corner of the building within a few feet of the cartridge cases.

As Fritz and Day were completing their examination of this rifle on the sixth floor, Roy Truly, the building superintendent, approached with information which he felt should be brought to the attention of the police. Earlier, while the police were questioning the employees, Truly had observed that Lee Harvey Oswald, 1 of the 15 men who worked in the warehouse, was missing. After Truly provided Oswald's name, address, and general description, Fritz left for police headquarters. He arrived at headquarters shortly after 2 p.m. and asked two detectives to pick up the employee who was missing from the Texas School Book Depository. Standing nearby were the police officers who had just arrived with the man arrested in the Texas Theatre. When Fritz mentioned the name of the missing employee, he learned that the man was already in the interrogation room. The missing School Book Depository employee and the suspect who had been apprehended in the Texas Theatre were one and the same--Lee Harvey Oswald.

The suspect Fritz was about to question in connection with the assassination of the President and the murder of a policeman was born in New Orleans on October 18, 1939, 2 months after the death of his father. His mother, Marguerite Claverie Oswald, had two older children. One, John Pie, was a half-brother to Lee from an earlier marriage which had ended in divorce. The other was Robert Oswald, a full brother to Lee and 5 years older. When Lee Oswald was Mrs. Oswald placed him in an orphanage where his brother and half-brother were already living, primarily because she had to work.

In January 1944, when Lee was 4, he was taken out of the orphanage, and shortly thereafter his mother moved with him to Dallas, Tex., where the older boys joined them at the end of the school year. In May of 1945 Marguerite Oswald married her third husband, Edwin A. Ekdahl. While the two older boys attended a military boarding school, Lee lived at home and developed a warm attachment to Ekdahl, occasionally accompanying his mother and stepfather on business trips around the country. Lee started school in Benbrook, Tex., but in the fall of 1946, after a separation from Ekdahl, Marguerite Oswald
