Alvin Ross Díaz had been a blackjack dealer at the Tropicana in Havana before the revolution. [Guillermo Novo](/people/guillermo-novo/) introduced him to [Michael Townley](/people/michael-townley/) in September 1976 as "a comrade." He was at the meeting in a New Jersey hotel room on the night of September 10 with Novo, [Virgilio Paz](/people/virgilio-paz/), and [José Dionisio Suárez](/people/jose-dionisio-suarez/) where Townley asked the [Cuban Nationalist Movement](/organizations/cuban-nationalist-movement/) to help kill [Orlando Letelier](/people/orlando-letelier/).[^1][^2]

### Trial

An FBI informant reported in January 1978 that "a young action oriented cell under the control of Francisco 'Frank' Castro of the [CORU](/organizations/coru/) organization," made up of Ross and Raciel Rodríguez, had bombed the Viasa Airlines office in Miami Beach on December 23, 1977. Indicted for the Letelier murders on August 1, 1978, Ross was tried with the Novo brothers from January 8, 1979. Sherman Kaminsky, a racketeer awaiting sentence who had met him in the Metropolitan Correctional Center in New York, testified that Ross said "he was involved in the murder of Orlando Letelier together with generals in DINA," called Townley "a traitor, a rat, an informer," called Letelier "a rotten Communist Marxist," said he was "glad Letelier was dead," admitted "he had contributed two wires used in the bomb," and said "he would not pay for Letelier's murder because the CIA would be the scapegoat, people would believe anything of the CIA." The sentencing judge had told Kaminsky: "I am going to suspend the operation of that sentence depending on how you come through." Ross was convicted on February 14, 1979, and sentenced to two concurrent life terms.[^2][^3]

On September 15, 1980, the court of appeals reversed: after *United States v. Henry*, decided that June, testimony so obtained was inadmissible. At the retrial in May 1981 Townley, asked what Ross had done to carry out the assassination, answered: "There is nothing I can think of." The jury acquitted Ross and Novo of the murders.[^2][^4]
