Pan Am Bank of Miami
1) Robert Ray McCowan, who ran guns to Castro when he was in the mountains, testified that he was paid for the guns in cash wrapped in Pan Am Bank wrappers. He was later visited in Texas at his ranch by Castro, who wanted him to be part of his administration. Shortly there after Lee Harvey Oswald and another man visited him attempting to purchase rifles and then Jack Ruby visited him seeking assistance in getting a friend out of a Cuban prison.
2) When Jack Ruby visited Cuba, he was supposed to bring a long entertainment writer Tony Zoppi, but Zoppi decided to cover the Rat Pack show in Vegas instead. So Ruby went to Havana himself, and visited his friend Louis McWillie, a pit boss at a casino owned by the Fox brothers. When he left Cuba, instead of flying to Dallas, Ruby flew to Miami, where he deposited a suitcase full of cash in the Fox brothers account at the Pan Am Bank.
3) Antonio Veciana said that after he was recruited by David Atlee Phillips, Phillips took him to an office in the Pan Am Bank in Miami where he was given a lie detector test, signed a security agreement and was given basic lessons in psychological warfare and clandestine tradecraft.
