Mr. Ball. Tenth Street is a block north of Jefferson?
Mr. McDonald. Yes, sir.
Mr. Ball. How did you happen to go to the 400 block on Jefferson?
Mr. McDonald. I was stopped by other officers there. They wanted to search a house. So I relieved my partner to go to help the supervisors search this house, in the 400 block of East Jefferson. Then I went around to the alleys, and started cruising the alley in my squad car.
Mr. Ball. And did you get a call over your radio to go to a certain place?
Mr. McDonald. Well, there was a report from the dispatcher that a suspect was seen running into the public library at Marsalis and Jefferson.
Mr. Ball. You went down there?
Mr. McDonald. Yes, sir. I went directly to Denver Street, which is an alley at that point. It is still designated as Denver Street. I parked the squad car, took my shotgun, and went to the west basement entrance to the public library, and ordered the people in the basement, in the library outside. They came out with their hands up.
The boy immediately said that he had just run into the library to tell the people that the President had been shot. He was a much younger person than what was broadcast on description on the radio.
Mr. Ball. You had heard a broadcast?
