In its 1978 investigation of the assassination of John F. Kennedy, the House Select Committee on Assassinations said that it recognized Jack Ruby's murder of Lee Harvey Oswald as a primary reason to suspect organized crime as possibly having involvement in the assassination. In its investigation, the HSCA noted the presence of "credible associations relating both Lee Harvey Oswald and Jack Ruby to figures having a relationship, albeit tenuous, with Marcello's crime family or organization". Their report stated: "The committee found that Marcello had the motive, means and opportunity to have President John F. Kennedy assassinated, though it was unable to establish direct evidence of Marcello's complicity".
