New Orleans attorney Dean Andrews Jr. testified to the Warren Commission on July 21, 1964 that he received a call from "Clay Bertrand," the day after the assassination of Kennedy, asking him to fly to Dallas to represent the suspected assassin, Lee Harvey Oswald. The FBI had reported two weeks after the assassination that Andrews, who had been hospitalized with pneumonia, said he was under heavy sedation and had concluded that the call had been a "figment of his imagination".
Nearly three years later on March 2, 1967, the New Orleans district attorney Jim Garrison asserted that "Clay Bertrand" was actually New Orleans businessman Clay Shaw who had conspired with Lee Harvey Oswald and David Ferrie to kill Kennedy. Shaw, who had been arrested and booked with conspiracy to commit murder, denied that he had ever used the name. An FBI document to President Lyndon Johnson's advisor W. Marvin Watson at the time of this development indicated that they had been unable to locate an individual by the name "Clay Bertrand."
Shortly after appearing before the Orleans Parish grand jury, Andrews stated in an interview on June 28, 1967 that "Bertrand" was not Shaw but was Eugene Davis, his friend and client. Davis denied in an affidavit that he was "Bertrand" or the person who suggested that Andrews go to Dallas to help Oswald. Andrews was subsequently convicted on three counts of perjury for lying to the grand jury on August 14, 1967. On February 25, 1969, Andrews testified during the trial of Clay Shaw that the name "'Clay Bertrand' was a figment of [his] imagination" and that he had been "carrying on a farce" in order to prevent "bring[ing] a lot of heat and trouble to someone who didn't deserve it." On March 1, 1969, the 34-day trial concluded when the jury acquitted Shaw after deliberating less than an hour.
