Mr. HUBERT. Now, Mrs. Cason, I have marked for the purposes of identification a document which is to be found in Commission’s report 81-A, which is entitled “Investigation of the Operational Security Involving the Transfer of Lee Harvey Oswald on November 24th, 1963.” On page 14, thereof, I have also marked Exhibit EE in that document, the following for the purposes of identification, “Dallas, Texas, April 1, 1964. Exhibit 5135, Deposition of Frances Cason and C. E. Hulse.” I have signed my name below that and ask you if you have not signed your name, for the purposes of identification, also on this same document? Mrs. CASON. Yes; I did. Mr. HUBERT. Will you state in your own words just exactly what part you had to do with this Exhibit 5135, which you now have before you? Mrs. CASON. You want me to just go ahead? Mr. HUBERT. Yes. Mrs. CASON. At approximately 11:20, or 11:21, I received a call from the basement of city hall there from Officer Slack, who works in the jail office. Mr. HUBERT. Did you know Officer Slack prior to this time? Mrs. CASON. Yes; I did. Mr. HUBERT. Had you spoken to him on the telephone before? Mrs. CASON. Yes; I have. Mr. HUBERT. Can you state that you are able to recognize his voice? Mrs. CASON. Yes; I did. Mr. HUBERT. Did you recognize the voice then speaking to you as being the voice of Officer Slack? Mrs. CASON. Yes; I did. Mr. HUBERT. All right; now, go ahead. Mrs. CASON. In addition, he told me it was Officer Slack when he called. It is not unusual for them to say, “This is Slack in the jail office.” So he would identify himself and ask to speak to Officer Farr, that is J. G. Farr, who is our corporal. Mr. HUBERT. How do you spell his last name? Mrs. CASON. [spelling] F-a-r-r. And he was in charge on that Sunday because we did not have a sergeant there, and he had asked to speak to Farr, and I told him Officer Farr was working channel 2, which is a separate channel that we have, and so he told me, he said, “They just shot Oswald,” or “Somebody just shot Oswald,” and I told him, “Okay.” And placed him on hold and told Farr that he had a red light on 531, and I proceeded to call the ambulance service on the hot line. Mr. HUBERT. Please describe the hot line? Mrs. CASON. The hot line is a straight line from our dispatcher office to the ambulance company which requires no dialing. You just lift it up and it rings from our office to theirs. Mr. HUBERT. So, then, immediately upon getting this information from Slack you passed it on to Farr by word of mouth? Mrs. CASON. I did not tell Officer Farr that Oswald had just been shot. I felt it was more important to get the ambulance and in time they would know soon enough. I told them he had a red light, and I knew Slack would tell him what happened in the basement. Mr. HUBERT. So then you flipped the button for the hot line at O’Neal Funeral Home? Mrs. CASON. Yes; I did. Mr. HUBERT. Did you get it immediately? Mrs. CASON. Yes.
