High Times - August 1996
One day after receiving a letter from the Assassination Records Review Board, a key witness in the murder of JFK was found dead in his home in California. Meanwhile, new evidence continues to pile up regarding Lee Harvey Oswald's connections to the CIA.
At 9 PM last November 1, the landlord of a house in the Echo Park section of Los Angeles unsuccessfully tried the locks, then pried open a window and forced his way inside. Robert Lavelle had been alerted by a neighbor that his tenant, 65-year-old Richard Case Nagell, had not been seen for several days. Lavelle discovered the already-decomposing body of Nagell in the bathroom, and immediately alerted the police.
autopsy performed by the L.A. County Coroner's office determined that Nagell had died of a heart attack, the timing triggered alarm inside the ARRB.
As outlined in my 1992 book about Nagell, The Man Who Knew Too Much (Carroll & Graf Publishers, New York), the ex-military intelligence and CIA operative...... a tape recording done surreptitiously by Nagell in the late summer of 1963, where at least four individuals--himself, Lee Harvey Oswald and two Cuban exiles--plotted the assassination of President Kennedy...Nagell has chosen to reveal about his role in the conspiracy goes like this: Under contract to the CIA, he undertook an assignment as a "double agent" who would cooperate with Soviet intelligence beginning in the autumn of 1962. Under KGB instructions from Mexico City, for a year he monitored discussions among a group of embittered Cuban exiles who were seeking to assassinate Kennedy and make it look as though Fidel Castro's Cuba was behind it. He was simultaneously asked to keep an eye on Lee Harvey Oswald, recently returned to America after his alleged "defection" to the USSR.
Oswald was brought into the conspiracy in July 1963, deceived into thinking he was working for Castro. Soviet intelligence ordered Nagell either to convince Oswald he was being set up to take the rap--or to kill him in Mexico City before the assassination could transpire. While both U S and Soviet intelligence agencies were aware of the conspiracy, it was the KGB--not the CIA or FBI--that attempted to prevent it. The Soviets, who had reached a growing accommodation with Kennedy after the 1962 Cuban missile crisis, were also afraid that the assassination would falsely be blamed upon them or the Cubans.
Nagell, instead of carrying out his assignment, sent a registered letter to FBI Director J. Edgar Hoover (which he also served as a confidential informant) more than two months before the tragedy in Dallas, providing enough information to warrant the arrest of Oswald and two Cuban exiles. While the bureau says it cannot locate any such letter in its files, it is likely that Nagell kept a copy and the registered-mail receipt among his effects.
According to Nagell the conspirators believed that if they set-up Lee Harvey Oswald, a well-known supporter of Fidel Castro with links to the Soviet Union, the assassination would result in a full-scale war against Cuba.
