In August 1959 Jack Ruby was invited to visit Cuba by the Dallas nightclub owner, Lewis McWillie. At that time McWillie was supervising gambling activities at Havana's Tropicana Hotel. Later, McWillie was involved in the campaign to have Fidel Castro overthrown after he had taken power from Fulgencio Batista.
Lewis McWillie worked as a professional gambler in Memphis, Tennessee (1932-36). Later he worked in Jackson, Mississippi, and Dallas, Texas (1940-58). Then he moved to the Deauville Casino in Cuba. A fellow worker at the casino was John Martino. McWillie was also a business associate of Santos Trafficante and Meyer Lansky and later ran the Tropicana Casino in Havana. In August 1959 Jack Ruby visited McWillie.
When Fidel Castro took control of of the island McWillie was arrested and then deported to the United States. After a period in Miami Meyer Lansky placed him inside of his Tropicana Casino in Las Vegas. In 1961 Sam Giancana and Johnny Roselli recruited McWillie to look after Frank Sinatra's Cal-Neva Lodge in Nevada.
On 17th November, 1963, McWillie was seen with Jack Ruby at the Thunderbird Casino Las Vegas. According to John William Tuohy: "Two days after meeting McWillie in Las Vegas, Ruby was back in Dallas, flush with nough cash to pay off his back taxes."
Rose Cheramie was found unconsciousness by the side of the road at Eunice, Louisiana, on 20th November, 1963. Lieutenant Francis Frudge of the Louisiana State Police took her to the state hospital. On the journey Cheramie said that she had been thrown out of a car by two gangsters who worked for Jack Ruby. She claimed that the men were involved in a plot to kill John F. Kennedy. Cheramie added that Kennedy would be killed in Dallas within a few days. Later she told the same story to doctors and nurses who treated her. As she appeared to be under the influence of drugs her story was ignored.
Following the assassination, Rose Cheramie was interviewed by the police. She claimed that Lee Harvey Oswald had visited Ruby's night club. In fact, she believed the two men were having a homosexual relationship. Cheramie, the victim of a hit and run driver, was found dead on 4th September, 1965.
The Warren Commission claimed that Jack Ruby was not "part of any conspiracy, domestic or foreign, to assassinate President Kennedy." It also stated that there was no "significant link between Ruby and organized crime". Critics of the Warren Report have claimed that this was not true.
