Mr. MAMANTOV. He is a petroleum independent operator, and if I'm not mistaken, he is connected with the Army Reserve, Intelligence Service. And, he asked me if I would translate for the police department and then immediately Mr. Lumpkin called me. Mr. JENNER. All right, that was your first---- Mr. MAMANTOV. This was a period of five minutes, I would say, maximum. Mr. JENNER. This, then, was your first contact with or connection with this tragedy? Mr. MAMANTOV. That's correct. Mr. JENNER. And you then came to the Dallas City Police Department, did you? Mr. MAMANTOV. Right. However, I called FBI about half an hour before the police called me. You see, I was in the dentist's office when I heard Lee Oswald's name, and when this name appeared on the radio, I felt it is my duty to notify the FBI that I know of him and knew fairly well his background here in Dallas. Mr. JENNER. And you so advised the FBI? Mr. MAMANTOV. Yes. Mr. JENNER. That was a half hour ahead of the time---- Mr. MAMANTOV. This was approximately, I would say---- Mr. JENNER. 4:30? Mr. MAMANTOV. 4:30. Mr. JENNER. I'll get into that background in a little while, Mr. Mamantov. You did go, then, to the Dallas City Police Station? Mr. MAMANTOV. They sent a police car. Mr. JENNER. To pick you up? Mr. MAMANTOV. To pick me up--it was quite disturbing because there was sirens and red lights and the neighborhood was quite disturbed. Mr. JENNER. Where did you reside at that time? Mr. MAMANTOV. 6911 East Mockingbird. Mr. JENNER. East Mockingbird? Mr. MAMANTOV. East Mockingbird Lane. Mr. JENNER. That's correct. And you were escorted into the Dallas City Police Station? Mr. MAMANTOV. That's correct and was introduced to Captain Fritz. Mr. JENNER. Go right ahead. Mr. MAMANTOV. He took me into a room filled up with the detectives--before we entered that room, I had to pass through the hallway filled up with the newspaper and TV and people. Mr. JENNER. You just went through that? Mr. MAMANTOV. I mean, I just went through with Captain Fritz there that I saw. Mr. JENNER. When you got into the room, now, whom did you see there? Mr. MAMANTOV. When I got into the room I saw Marina, I saw Mrs. Paine, whom I knew, who has been once in our house, and I have numerous telephone conversations with her in regard to her learning Russian. Mr. JENNER. Does Mrs. Gravitis live with you? Mr. MAMANTOV. That's correct. Mr. JENNER. When you say "our house," that's the house in which you, your wife and Mrs. Gravitis reside? Mr. MAMANTOV. That's correct. She resides with us since 1943--we never were separated. Mr. JENNER. Is her first name Dorothy? Mr. MAMANTOV. Dorothy, and I saw Mrs. Paine and I saw next to her a young woman with a young baby whom I assumed to be Marina Oswald. Mr. JENNER. Have you ever seen Marina Oswald in your life prior to that moment? Knowingly? Mr. MAMANTOV. No; sir. Mr. JENNER. Had you ever met her prior to that time?
