After passing Scoggins, the gunman crossed to the west side of Patton Avenue and ran south toward Jefferson Boulevard, a main Oak Cliff thoroughfare. On the east side of Patton, between 10th Street and Jefferson Boulevard, Ted Callaway, a used car salesman, heard the shots and ran to the sidewalk. As the man with the gun rushed past, Callaway shouted “What’s going on?” The man merely shrugged, ran on to Jefferson Boulevard and turned right. On the next corner was a gas station with a parking lot in the rear. The assailant ran into the lot, discarded his jacket and then continued his flight west on Jefferson.

In a shoe store a few blocks farther west on Jefferson, the manager, Johnny Calvin Brewer, heard the siren of a police car moments after the radio in his store announced the shooting of the police officer in Oak Cliff. Brewer saw a man step quickly into the entranceway of the store and stand there with his back toward the street. When the police car made a U-turn and headed back in the direction of the Tippit shooting, the man left and Brewer followed him. He saw the man enter the Texas Theatre, a motion picture house about 60 feet away, without buying a ticket. Brewer pointed this out to the cashier, Mrs. Julia Postal, who called the police. The time was shortly after 1:40 p.m.

At 1:29 p.m., the police radio had noted the similarity in the descriptions of the suspects in the Tippit shooting and the assassination. At 1:45 p.m., in response to Mrs. Postal’s call, the police radio sounded the alarm: “Have information a suspect just went in the Texas Theatre on West Jefferson.” Within minutes the theater was surrounded. The house lights were then turned up. Patrolman M. N. McDonald and several other policemen approached the man, who had been pointed out to them by Brewer.

McDonald ordered the man to his feet and heard him say, “Well, it’s all over now.” The man drew a gun from his waist with one hand and struck the officer with the other. McDonald struck out with his right hand and grabbed the gun with his left hand. After a brief struggle McDonald and several other police officers disarmed and handcuffed the suspect and drove him to police headquarters, arriving at approximately 2 p.m.

Following the assassination, police cars had rushed to the Texas School Book Depository in response to the many radio messages reporting that the shots had been fired from the Depository Building. Inspector J. Herbert Sawyer of the Dallas Police Department arrived at the scene shortly after hearing the first of these police radio messages at 12:34 p.m. Some of the officers who had been assigned to the area of Elm and Houston Streets for the motorcade were talking to witnesses and watching the building when Sawyer arrived. Sawyer entered the building and rode a passenger elevator to the fourth floor, which was the top floor for this elevator. He conducted a quick search, returned to the main floor and, between approximately 12:37 and 12:40 p.m., ordered that no one be permitted to leave the building.

Shortly before 1 p.m. Capt. J. Will Fritz, chief of the homicide and robbery bureau of the Dallas Police Department, arrived to take charge of the investigation. Searching the sixth floor, Deputy Sheriff Luke Mooney noticed a pile of cartons in the southeast corner. He squeezed through the boxes and realized immediately that he had discovered the point from which the shots had been fired. On the floor were three empty cartridge cases. A carton had apparently been placed on the floor at the side of the window so that a person sitting on the carton could look down Elm Street toward the overpass and scarcely be noticed from the outside. Between this carton and the half-open window were three additional cartons arranged at such an angle that a rifle resting on the top carton would be aimed directly at the motorcade as it moved away from the building. The high stack of boxes, which first attracted Mooney’s attention, effectively screened a person at the window from the view of anyone else on the floor.

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. C. 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 Pic, 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 3, 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 reentered Lee in the first grade in Covington, La. In January 1947, while Lee was still in the first grade, the family moved to Fort Worth, Tex., as the result of an attempted reconciliation between Ekdahl and Lee’s mother. A year and a half later, before Lee was 9, his mother was divorced from her third husband as the result of a divorce action instituted by Ekdahl. Lee’s school record during the next 5½ years in Fort Worth was average, although generally it grew poorer each year. The comments of teachers and others who knew him at that time do not reveal any unusual personality traits or characteristics.
