It is now ordinarily referred to as the city hall, the building which is on the corner of Main, Harwood and Commerce, which is the old city hall, now known as the Police and Courts Building, and houses the jail, the police department, and one or two offices of our city government. But primarily it is referred to, or should be referred to as the Police and Courts Building. Mr. HUBERT. All right. Now, go on. So you arrived back at the police department. Mr. STEVENSON. We arrived back at the office about 4 o'clock, or maybe a few minutes later. I went directly to the homicide bureau. Chief Batchelor went to the administrative offices. Before leaving the Trade Mart, I had gotten information through Captain Souter that the suspect in the shooting of Officer Tippit had been arrested. On the air on the way to the hospital, we heard several squads being dispatched to Texas Theatre. I asked the dispatcher what we had working at Texas Theatre, and he advised me that it was the suspect who had shot Officer Tippit, that he had been arrested at the Texas Theatre. At that time I advised them that Chief Batchelor and myself, or "2" and "3," as I told him, which are our call numbers, were en route to Parkland Hospital and would be in the area and back to the office as soon as possible. When I arrived back at the city hall I went to the homicide bureau to see what progress on our investigation was made, I was advised that Oswald had definitely been identified in murder of Officer Tippit. Mr. HUBERT. Who advised you of this? Mr. STEVENSON. Lieutenant Wells in the homicide office. Mr. HUBERT. Did you see Oswald at that time? Mr. STEVENSON. No, sir; I didn't; he was being interviewed, but I did not see him. Mr. HUBERT. Who was interviewing him? Mr. STEVENSON. Captain Fritz and some FBI agent, I don't know who, and I believe a Secret Service agent. Mr. HUBERT. Are you aware now of a message that had been sent by the FBI to the Dallas Police Department concerning the security of Oswald? Mr. STEVENSON. Not at that time, no, sir. That was Friday afternoon? Mr. HUBERT. Yes; but you didn't learn that Mr. Hoover had sent word that great care should be taken for the security? Mr. STEVENSON. Not at that time, I had not; no, sir. Mr. HUBERT. Will you tell us without detail, generally speaking, of your activities on the rest of the 22d, and the 23d. Mr. STEVENSON. After I was advised that he had definitely been identified and from evidence which was being checked, it looked like he possibly might be the same man who shot the President. I returned to my office in the administrative offices, and was in and out of the homicide bureau on numerous times, staying in touch with the investigation, and they were in touch with my office. About 7 p.m., I believe it was 7, approximately 7, Oswald was filed on for the murder of Officer Tippit, and was arraigned in the Police and Courts Building by Justice of the Peace Dave Johnston, I believe it was.
