Mr. Ball. Had you seen anybody over at the railroad yard north and west of the bookstore before you heard the shots fired?
Mr. Foster. No; other than people that had come up there and I sent them back down the roadway.
Mr. Ball. I see. People had attempted to get on the overpass there?
Mr. Foster. Yes, sir.
Mr. Ball. And you had sent them away?
Mr. Foster. Yes, sir.
Mr. Ball. When you got over to the School Book Depository Building, what did you do?
Mr. Foster. I was standing around in back there to see that no one came out, and the sergeant came and got me and we were going to check the—all the railroad cars down there.
Mr. Ball. Who was that sergeant?
Mr. Foster. Sergeant came up there.
