Herminio Diaz Garcia was born in Cuba in 1923. He was a member of the Cuban Restaurant Workers Union and worked as a cashier at the Hotel Habana-Rivera. Later he became involved in illegal activities and eventually became a bodyguard for Santos Trafficante.
Diaz Garcia killed Pipi Hernandez in 1948 at the Cuban Consulate in Mexico. In 1957 he was involved with an assassination attempt against President Jose Figures of Costa Rica.
Diaz Garcia moved to the United States in July, 1963, where he worked for Tony Varona. Some researchers believe that Dia Garcia was one of the gunman who killed John F. Kennedy on 22nd November, 1963.
In December, 1963, Dia Garcia was involved in an unsuccessful attempt to assassinate Fidel Castro. He was also involved in providing weapons to anti-Castro groups.
Diaz Garcia was killed on a mission at Monte Barreto in the Miramar district of Cuba on 29th May, 1966. Tony Cuesta was captured during the mission. Cuesta, who always vowed that Castro would never take him alive, attempted suicide by setting off a grenade, which blinded him and blew off his right hand. Cuesta spent a long time in hospital as a result of his serious injuries. Herminio Diaz Garcia is buried in Columbus, Havana.
In 1978 President Jimmy Carter arranged for a group of imprisoned exiles in Cuba to be released. This included Tony Cuesta who was involved in an attack on Cuba in 1966. Just before leaving Cuba Cuesta asked to see Fabian Escalante. Cuesta told Escalante that he had been involved in the assassination of President John F. Kennedy. He also named Diaz Garcia and Eladio del Valle as being involved in the conspiracy. Cuesta asked Escalante not to make this information "made public because I am returning to my family in Miami - and this could be very dangerous."
Tony Cuesta returned to Miami and died in 1994. The following year, Wayne Smith, chief of the Centre for International Policy in Washington, arranged a meeting on the assassination of John F. Kennedy, in Nassau, Bahamas. Others in attendance were: Gaeton Fonzi, Dick Russell, Noel Twyman, Anthony Summers, Peter Dale Scott, Jeremy Gunn, John Judge, Andy Kolis, Peter Kornbluh, Mary and Ray LaFontaine, Jim Lesar, John Newman, Alan Rogers, Russ Swickard, Ed Sherry, and Gordon Winslow.
Some high-level Cuban officials attended the conference. This included Fabian Escalante, Carlos Lechuga, former Cuban diplomat, and Arturo Rodriguez, a State Security official. Escalante revealed details of Cuesta's confession. He also informed the group they had a spy in the anti-Castro community in Miami and knew about the plot to kill Kennedy.
