Mr. WALKER. I worked--I went back to Slaton, Tex., and worked for my uncle there for 1 year drilling irrigation wells. Mr. BELIN. After that what did you do? Mr. WALKER. I came back to Grand Prairie and went to work there and worked there 5-1/2 years. Mr. BELIN. Doing what? Mr. WALKER. Aircraft mechanic and electrical work. Mr. BELIN. Then what did you do? Mr. WALKER. I came to work for the Dallas Police Department. Mr. BELIN. When was that? Mr. WALKER. 1959, July the 27th. Mr. BELIN. And you have been there ever since? Mr. WALKER. Yes, sir. Mr. BELIN. Were you on duty on November 22, 1963? Mr. WALKER. Yes; I was. Mr. BELIN. Will you state where you were on duty around 12 or 12:30 or so on that day? Mr. WALKER. I was at Jefferson and Tenth Street at the fire station. Mr. BELIN. Is that in the Oak Cliff section there? Mr. WALKER. Yes; it is. Mr. BELIN. What were you doing there? Mr. WALKER. I was cruising the area and I had heard on the radio about the disturbance downtown, so I checked out at the fire station. I didn't check out. I just stopped and went in and listened to the news broadcast to find out in more detail what happened. Mr. BELIN. Were you cruising alone at that time? Mr. WALKER. Yes. Mr. BELIN. Is it general procedure for officers cruising in the daytime to work alone or in pairs? Mr. WALKER. Accident investigations, we work alone. That is day and night. Mr. BELIN. Day and night? Mr. WALKER. Yes. Mr. BELIN. What about nonaccident investigation? Do you know offhand? Mr. WALKER. Radio patrol work, one man during the day. Second and third platoon, they work two men. Mr. BELIN. That would be the second platoon would come to work about 4 in the afternoon? Mr. WALKER. Yes, sir. Mr. BELIN. Did you know Officer J. D. Tippit? Mr. WALKER. Yes. Mr. BELIN. Ever work with him at all? Mr. WALKER. I believe I have. I can't recall. I worked at the same substation he did before I transferred downtown, and I knew him quite well. I talked to him. He worked at Austin, and I have talked to him there. Mr. BELIN. Well, let's leave Officer Tippit for the moment and return to the fire station. You were there and you say you called in around shortly after you heard the news? Mr. WALKER. Yes. I went directly there. I was about a block away or might have been in the block I don't recall exactly. Mr. BELIN. You mean a block away from the fire station? Mr. WALKER. Yes. Mr. BELIN. Then what did you do when you called in? Mr. WALKER. I didn't call in. I just went in there and looked. They have a television there, and they broadcast that the President had been shot. I had my radio up so I could hear from the door, and I went back out to my car. They were sending squads downtown, Code 3. And I don't recall, I don't believe they actually sent me. I just went on my own because they normally don't send us in this type of call. Mr. BELIN. So you went on your own where? Mr. WALKER. I went to the Texas School Book Depository.
