Mr. Ball. What did you do?
Mr. McDonald. I told my partner we were not doing much good here, to go to Oak Cliff, and see if we could help out over there, try to apprehend the person that shot Tippit.
Mr. Ball. Did you?
Mr. McDonald. Yes, sir.
Mr. Ball. Where did you go in Oak Cliff?
Mr. McDonald. Well, we got in the car and went underneath the triple underpass and got on the Stemmons Expressway, which leads into the R. L. Thornton Expressway. I believe we took the Jefferson exit and drove up to the 400 block of East Jefferson.
Mr. Ball. Patton is about a block to the north of Jefferson?
Mr. McDonald. Patton runs across Jefferson. Tenth and Patton.
Mr. Ball. Patton runs north and south?
Mr. McDonald. Yes, sir.
