The focal center of the Police and Courts Building during Oswald’s detention was the third floor, which housed the main offices of the Dallas Police Department. The public elevators on this floor opened into a lobby midpoint of a corridor that extended along the length of the floor for about 140 feet. At one end of this 7-foot-wide corridor were the offices occupied by Chief of Police Jesse E. Curry and his immediate subordinates; at the other end was a small pressroom that could accommodate only a handful of reporters. Along this corridor were other police offices, including those of the major detective bureaus. Between the pressroom and the lobby was the complex of offices belonging to the homicide and robbery bureau, headed by Capt. J. Will Fritz.[C5-1] (See Commission Exhibit No. 2175, p. 197.) [Illustration: COMMISSION EXHIBIT NO. 2175 THIRD FLOOR PLAN DALLAS POLICE DEPARTMENT DALLAS, TEXAS] Chronology The policemen who seized Oswald at the Texas Theatre arrived with him at the police department building at about 2 p.m. and brought him immediately to the third floor offices of the homicide and robbery bureau to await the arrival of Captain Fritz from the Texas School Book Depository. After about 15 or 20 minutes Oswald was ushered into the office of Captain Fritz for the first of several interrogation sessions.[C5-2] At 4:05 p.m. he was taken to the basement assembly room for his first lineup.[C5-3] While waiting outside the lineup room, Oswald was searched, and five cartridges and other items were removed from his pockets.[C5-4] After the lineup, at about 4:20, Oswald was returned to Captain Fritz’ office for further questioning.[C5-5] Two hours later, at 6:20 p.m., Oswald was taken downstairs for a second lineup and returned to Captain Fritz’ office within 15 minutes for additional interrogation.[C5-6] Shortly after 7 p.m., Captain Fritz signed a complaint charging Oswald with the murder of Patrolman Tippit. Oswald was formally arraigned, i.e., advised of the charges, at 7:10 p.m., before Justice of the Peace David L. Johnston, who came to Captain Fritz’ office for the occasion.[C5-7]
