[1] He served in several branches of the United States military and in the Cuban Revolution of 1958, worked as an undercover operative for the Central Intelligence Agency,[2] and was alleged to be involved in the assassination of John F. Kennedy.

[3] "On April 14, 1942, William Donovan, as Coordinator of Information (forerunner of the Office of Strategic Services), activated units charged with gathering intelligence, harassing the Japanese through guerrilla actions, identifying targets for the Army Air Force to bomb, and rescuing downed Allied airmen.

"[4] This was what led to Stilwell's Chinese forces, Wingate's Raiders, and Merrill's Marauders involvement in the war,[5] and Frank got trained in guerrilla tactics and gathering intelligence, which became useful in his later events.

[citation needed] Honorably discharged as a corporal in 1945, he enrolled at Virginia Polytechnic Institute but left college and joined the Norfolk Police Department on June 5, 1946.

They were sending money to Mexico to support Fidel Castro, whose July 26 Movement had arranged a meeting between CIA Inspector General Lyman Kirkpatrick and their representatives in 1957 by Pepín Bosch, an executive of the Bacardi Corporation.

In March 1958, Sturgis opened a training camp in the Sierra Maestra mountains, where he taught Che Guevara and other 26th of July Movement rebel soldiers guerrilla warfare.

[15] When Castro seized power, a rebel firing squad on San Juan Hill executed 71 of their opponents on January 11, 1959, into an awaiting 40-foot (12.2 m) ditch that had been opened with a bulldozer.

[16] His friend Richard Sanderlin, completed the training of Raul Castros Second Front, and led a guerrilla band into combat operations against the Cuban army of Batista.

Castro then appointed Sturgis gambling czar and director of security and intelligence for the air force, in addition to his position as a captain in July 26 Movement.

Sturgis defected the following month with Revolutionary Air Force chief Commandant Pedro Luis Díaz Lanz[19] and they joined the anti-Castro exile opposition.

Sturgis formed the Anti-Communist Brigade which Hans Tanner in his book "Counter-Revolutionary Agent", says the organization was "being financed by dispossessed hotel and gambling owners" from Cuba.

The Border Patrol in Miami reported that Sturgis was involved in a CIA operation being financed by Sergio Rojas (former Cuban Ambassador to Great Britain) to overthrow Castro.

It has been claimed, with little in the way of evidence, that Sturgis was involved in helping the CIA organize the Bay of Pigs Invasion, for whose ultimate failure he blamed President Kennedy.

Bob Woodward, a reporter working for The Washington Post was told by a source (Deep Throat) who was employed by the government that senior aides of President Richard Nixon had paid the burglars to obtain information about his political opponents.

[35] According to Vincent Bugliosi, allegations that these men were involved in a conspiracy originated from theorist Richard E. Sprague who compiled the photographs in 1966 and 1967, and subsequently turned them over to Jim Garrison during his investigation of Clay Shaw.

[36] Comedian and civil rights activist Dick Gregory helped bring national media attention to the allegations against Hunt and Sturgis in 1975 after obtaining the comparison photographs from Weberman and Canfield.

[36] Immediately after obtaining the photographs, Gregory held a press conference that received considerable coverage and his charges were reported in Rolling Stone and Newsweek.

[39] The final report of that commission stated that witnesses who testified that the "derelicts" bore a resemblance to Hunt or Sturgis "were not shown to have any qualification in photo identification beyond that possessed by an average layman".

[42] In 1992, journalist Mary La Fontaine discovered the November 22, 1963, arrest records that the Dallas Police Department had released in 1989, which named the three men as Gus W. Abrams, Harold Doyle, and John F.

[43] According to the arrest reports, the three men were "taken off a boxcar in the railroad yards right after President Kennedy was shot", detained as "investigative prisoners", described as unemployed and passing through Dallas, then released four days later.

[44][45] Sturgis stated he was revealing that he made the reports in order to refute "the leftist element in the country" who claimed the CIA was involved in the assassination of Kennedy.

[49] In September 1977, Marita Lorenz told Paul Meskil of the New York Daily News that she met Oswald in the fall of 1963 at an Operation 40 safe house in the Little Havana section of Miami.

[23] Lorenz stated that she joined the men traveling to Dallas in two cars and carrying "rifles and scopes", but flew back to Miami the day after they arrived.

[54][55] The two sons alleged that their father cut the information from his memoirs, American Spy: My Secret History in the CIA, Watergate and Beyond, to avoid possible perjury charges.

[53] Sturgis is also linked to the assassination, on December 4, 1980, of Portuguese prime minister Francisco de Sá Carneiro and 6 other people aboard a Cessna aircraft, in what became known as the Camarate affair.

He was named by two of his alleged accomplices, Fernando Farinha Simões and José Esteves, in a written confession,[56] as the person who pressed the button of the detonator to activate the bomb on the plane.

In 1979, Sturgis traveled to Angola to help rebels fighting the communist government, which was supported by Cuba and the Soviet Union, and to teach guerrilla warfare.
