Mr. ELY. Could you tell us what your occupation is? Mr. PIERCE. Officer--police officer. Mr. ELY. And what rank do you hold? Mr. PIERCE. Lieutenant. Mr. ELY. You are a lieutenant with the Dallas Police Department? Mr. PIERCE. That's right. Mr. ELY. Could you tell us something about what you did before you started to work for the police department? Mr. PIERCE. Well, I was raised on a farm out in West Texas and engaged in farming practically all of my life up until I went in the Marine Corps. After I got out of the Marine Corps in 1946, in April I believe it was, I came to the Dallas Police Department in August 1946. Mr. ELY. Could you tell us, please, what your job is? What do you specialize in with the police department? Mr. PIERCE. I am assigned as a lieutenant in the patrol division out of the central station. Mr. ELY. Now, were you on duty on November 22, 1963? Mr. PIERCE. I was not. Mr. ELY. Were you in Dallas on that date? Mr. PIERCE. Part of the day. I went to Ennis, Tex., early that morning and returned to Dallas about--oh, it was approximately 1 or 1:30 p.m. Mr. ELY. Did you have anything to do with the investigation of the killing of either President Kennedy or Officer Tippit? Mr. PIERCE. No, sir. Mr. ELY. I will show you three exhibits, one is a map designated Putnam Exhibit No. 1. The other two are designated Sawyer Deposition Exhibits A and B, and are copies of the Dallas Police Department's radio logs for November 22, 1963. If you will for the moment assume that Officer Tippit was assigned to patrol the district marked No. 78 on Putnam Exhibit No. 1. Can you explain why, subsequent to the shooting of the President, Officer Tippit would be in the district marked 109--specifically at the corner of Lancaster and Eighth--at 12:54 p.m., and then would later have proceeded into district 91, which is the area in which he was shot and killed? Will you look at these radio logs to see if you can find any calls which would lead him to take this route? Use any other information at your disposal to explain to us why he would have gone out of district 78 and over into Nos. 109 and 91? Mr. PIERCE. Well, I see one transmission here that I think would have alerted any officer knowing the fact that the President was in town, at 12:43--I believe this occurred on channel 1--this was taken from channel 1 recordings at 12:43. It says, "Attention all squads of downtown area, code 3 to Elm and Houston with caution." Mr. ELY. Explain what code 3 means.
