In his 2013 book "The Hidden History of the JFK Assassination", Lamar Waldron claimed that Marcello masterminded the assassination of Kennedy. According to Waldron, Marcello admitted his involvement to two other inmates during a fit of rage in the prison yard at the Federal Correctional Institution in Texarkana, Texas. In his book, Waldron also presented the account of Marcello's prison cell mate, Jack Van Laningham, who claimed in 1985 that Marcello bragged to him that he had masterminded the Kennedy assassination, while planting red herrings to confuse the press and embarrass the FBI and CIA into suppressing evidence. According to Waldron, Marcello arranged for two hit men to carry out the assassination after entering the United States from Canada and Europe, while setting up Oswald as the fall guy and ordering the subsequent murder of various conspirators and witnesses who risked turning informants, including mobsters Johnny Roselli and Sam Giancana.
