Yakhliel remembers hearing Oswald, who used the name Alek, speak highly of President Kennedy.

"One day he was at our house and the television was showing a meeting between Khrushchev and Kennedy. You may remember that meeting; I don't remember what year it was exactly. And he spoke about Kennedy very sympathetically. He said he was the only sensible president. Those were his words," said Yakhliel.

The commission led by U.S. Chief Justice Earl Warren concluded Oswald acted alone in killing the president, but Shushkevich, Markava, and Yakhliel can't accept that conclusion. They believe there must have been some form of conspiracy.

"It is my absolute conviction that they found a passive, calm, compliant boy, and used him as the guilty one. And then they washed their hands of it. As for the conclusions of the Warren Commission, I don’t believe them one bit. I have studied them and I don’t think it was the work of my student," said Shushkevich.

"I didn't believe he could have done it. It seemed to me that he was framed, using the whole situation with the Soviet Union. I didn't think he could have done it. Or he would have been completely insane to do it,” added Markava.

"None of us, none of his friends here, believed it. Some knew him a lot less that I did - actually, they knew Marina more than Alek. But I came to know him well. I don't believe it," Yakhliel said.

Lee Harvey Oswald appeared to be a different man in different places with different people. He showed the world many faces.
