Mr. MARTELLO. Yes, sir; I did. I made a personal history background investigation, which is a common practice and when dealing with any person affiliated with any organization that demonstrates in the city, and also to attempt to ascertain their ideologies and find out in what area they would most likely demonstrate, on what side of the fence, so to speak, as we call it, and see whether or not they were potential agitators or troublemakers. This would assist the department in planning for future demonstrations by these persons if they so demonstrated. Mr. LIEBELER. Now after you interviewed Oswald and made these notes, it is my understanding that while you did not prepare a memorandum on your interview at that time, you subsequently, that is, after the assassination, on the basis of the notes you did make at the time you interviewed Oswald, you prepared a memorandum setting forth the results of your interview with Oswald. Is that correct? Mr. MARTELLO. That is correct, sir. Mr. LIEBELER. Can you tell us approximately when you did interview him? Mr. MARTELLO. [referring to notes]. I interviewed Oswald at 10 a.m. on Saturday, August 10, 1963. Mr. LIEBELER. That would have been the day following his arrest? Is that correct? Mr. MARTELLO. That is correct, sir. Mr. LIEBELER. August 9 would have been a Friday? Is that correct? Mr. MARTELLO. Yes; that is correct. The day of his arrest was on Friday, August 9, 1963. Mr. LIEBELER. I also understand that you provided a copy of the memorandum that you did prepare to the FBI? Is that correct? Mr. MARTELLO. Originally--wait--originally I was contacted by the U.S. Secret Service on the morning after the assassination of the President at approximately 3 o'clock in the morning, and I was interviewed concerning what information I had developed at the time of the interview. Mr. LIEBELER. Do you remember which agent of the Secret Service did talk to you? Mr. MARTELLO. Yes; I remember something like Querie. No; I believe it was Mr. Vial, V-i-a-l, who originally spoke to me, and since that time there were numerous phone calls to my home and at work with various members of the U.S. Secret Service who spoke to me concerning the interview that I had with Harvey Oswald. Mr. LIEBELER. Did you also turn over to the Secret Service or to the FBI the pamphlets and other materials that had been found in Oswald's possession at the time of his arrest? Mr. MARTELLO. That is correct, sir. I turned that information over to the Secret Service. Mr. LIEBELER. Then you subsequently prepared the memorandum to which we have already referred, and you provided a copy of that memorandum to the Secret Service or to the FBI? Is that correct? Mr. MARTELLO. That is correct, sir. Mr. LIEBELER. [Exhibiting document to witness.] I want to show you a copy of your memorandum, and I will ask you if you yourself have a copy of your memorandum with you. Mr. MARTELLO. No, sir.
