Eugenio (Musculito) Martinez was born in Cuba. He moved to Miami after Fidel Castro gained power in 1959. Over the next few years Martinez became an active member of the anti-Castro Cuban movement in the United States.
In the winter of 1962 Eddie Bayo claimed that two officers in the Red Army based in Cuba wanted to defect to the United States. Bayo added that these men wanted to pass on details about atomic warheads and missiles that were still in Cuba despite the agreement that followed the Cuban Missile Crisis.
