Hemming was convicted by a Miami jury of conspiracy to import marijuana. In 1978 he was sentenced to six months in prison by U.S. District Judge
William Hoeveler. Hemming was released on appeal bond and the conviction was later overturned. In August, 1978,
Victor Marchetti published an article about the assassination of John F. Kennedy in the
Liberty Lobby newspaper,
The Spotlight. In the article Marchetti argued that the
House Select Committee on Assassinations (HSCA) had obtained a 1966 CIA memo that revealed Hemming,
E. Howard Hunt, and
Frank Sturgis had been involved in the plot to kill Kennedy. Marchetti's article also included a story that
Marita Lorenz had provided information on this plot. On April 14, 1980, Hemming was arrested and charged with drug trafficking. He was held on $200,000 bond in
Palm Beach County, Florida. He claimed that he had not smuggled
Quaaludes, but was establishing his bona fides with drug traffickers so he could penetrate their networks. Hemming told Alan J. Weberman that he was working for
Mitchell Werbell III and
Lucien Conein. Hemming was sentenced to 35 years in prison with a minimum mandatory sentence of three years but the conviction was later overturned on appeal. Hunt decided to take legal action against the Liberty Lobby. In December, 1981, he was awarded $650,000 in damages. Liberty Lobby appealed to the United States Court of Appeals. It was claimed that Hunt's attorney,
Ellis Rubin, had offered a clearly erroneous instruction as to the law of defamation. The three-judge panel agreed and the case was retried. This time
Mark Lane defended the Liberty Lobby against Hunt's action. Lane eventually discovered Marchetti's sources. The main source was
William R. Corson. It also emerged that Marchetti had also consulted
James Angleton and
A. J. Weberman before publishing the article. As a result of obtaining depositions from
David Atlee Phillips,
Richard Helms,
G. Gordon Liddy,
Stansfield Turner, and
Marita Lorenz, plus a skillful cross-examination by Lane of
E. Howard Hunt, the jury decided in January, 1985, that Marchetti had not been guilty of libel when he suggested that John F. Kennedy had been assassinated by people working for the CIA. Lane stated that during a later meeting they had, Hemming corroborated the details of the assassination which were outlined during the trial. ==Later life==
