Mr. BELIN. What about Exhibit 502? Mr. TRULY. This is the lunchroom looking west. Northwest, I would say. Mr. BELIN. Is this door clear to the left of the picture, the door in which you saw Officer Baker standing when he was talking to Lee Harvey Oswald? Mr. TRULY. Yes, sir. Mr. BELIN. Now, Mr. Truly, you then went up to the third floor with Officer Baker. Mr. TRULY. We continued on until we reached the fifth floor. Mr. BELIN. Now, by the way, I have used the name Officer Baker. When did you find out what his name was? Mr. TRULY. I never did know for sure what his name was until he was down to the building and you were interviewing him last week. Mr. BELIN. This was on Friday, March 20th? Mr. TRULY. I had heard his name was Baker or Burton or various other names. But I never did try to find out what his name was. Mr. BELIN. All right. (The document referred to was marked Commission Exhibit No. 502 for identification.) Mr. BELIN. Now, Mr. Truly, did you notice when you got to the third floor--first of all. On the second floor, was there any elevator there? Mr. TRULY. No, sir. Mr. BELIN. What about the third floor? Mr. TRULY. No, sir. Mr. BELIN. Fourth floor? Mr. TRULY. No, I am sure not. Mr. BELIN. What about the fifth floor? Mr. TRULY. When we reached the fifth floor, the east elevator was on that floor. Mr. BELIN. What about the west elevator? Was that on the fifth floor? Mr. TRULY. No, sir. I am sure it wasn't, or I could not have seen the east elevator. Mr. BELIN. All right. Mr. TRULY. I am almost positive that it wasn't there. Mr. DULLES. You said you released the elevator and let it go down? Mr. TRULY. No; the east elevator was the one on the fifth floor. Mr. BELIN. Now, Exhibit 487 appears to be a diagram of the fifth floor. As I understand it, you might mark on that diagram the way you went from the stairs over to the east elevator. Mr. TRULY. Well, I started around towards the stairway, and then I noted that this east elevator was there. So I told the officer, "Come on, here is an elevator," and then we ran down to the east side, and got on the east elevator. Mr. BELIN. Could you put the letter "T" at the end of that line, please? All right. Now, where did you go with the east elevator, to what floor? Mr. TRULY. We rode the east elevator to the seventh floor. Mr. BELIN. Did you stop at the sixth floor at all? Mr. TRULY. No, sir. Mr. BELIN. What did you do when you got to the seventh floor? Mr. TRULY. We ran up a little stairway that leads out through a little penthouse on to the roof. Mr. BELIN. What did you do on the roof? Mr. TRULY. We ran immediately to the west side of the building. There is a wall around the building that you cannot see over without getting your foot between the mortar of the stones and, or some such toehold. We did that and looked over the ground and the railroad tracks below. There we saw many officers and a lot of spectators, people running up and down.
