On March 1, 1967, New Orleans District attorney [[Jim Garrison]] arrested and charged New Orleans businessman [[Clay Shaw]] with having conspired to assassinate [[John F. Kennedy|President Kennedy]].<ref name="Gulyas2015"/>{{rp|30}}<ref name="Peebles"/>{{rp|263}} Fred Crisman was subpoenaed by Garrison and testified before the New Orleans grand jury in the case.<ref name="Peebles"/>{{rp|263}} Garrison issued a press release accusing Crisman of being an undercover agent with knowledge of the Kennedy Assassination.<ref name="MirageMen"/>

The jury took less than an hour to find Shaw not guilty.<ref name="Peebles"/>{{rp|323}} Garrison's prosecution of Shaw was highly criticized as "a fatally flawed case built on flimsy evidence that featured a chorus of dubious and even wacky witnesses" while others more pointedly accuse Garrison of "recklessness, cruelty, abuse of power, publicity mongering and dishonesty".<ref name="UPI; October 22, 1992">{{cite news |author=<!--not stated--> |date=October 22, 1992 |title=Former New Orleans DA, Kennedy prober, Jim Garrison dies |url=https://www.upi.com/Archives/1992/10/22/Former-New-Orleans-DA-Kennedy-prober-Jim-Garrison-dies/9416719726400/ |work=upi.com |agency=UPI |access-date=February 7, 2023}}</ref><ref>{{cite news |last=Will |first=George |author-link=George Will |date=December 26, 1991 |title='JFK': PARANOID HISTORY |url=https://www.washingtonpost.com/archive/opinions/1991/12/26/jfk-paranoid-history/1353d5cd-9d26-4088-acf7-d3ba5a0f8a0d/ |newspaper=The Washington Post |access-date=February 7, 2023}}</ref><ref>{{cite news |last=Posner |first=Gerald |author-link=Gerald Posner |date=August 6, 1995 |title=Garrison Guilty.

Despite the near-universal condemnation of the prosecution, conspiracy theories continued to link Crisman to the Kennedy assassination and a supposed UFO cover-up. Crisman had been involved in the Shaver Mystery and the Maury Island Hoax in the 1940s. In the late 1970s, the [[United States House Select Committee on Assassinations]] considered the possibility that Crisman may have been one of the [[Three tramps|"three tramps"]] detained and photographed in the aftermath of the JFK assassination.<ref name="RToronto"/>{{rp|160}} Pointing to Crisman's supposed involvement, later conspiracy authors like Kenn Thomas, Jim Marrs, and Bill Cooper alleged that Kennedy's assassination was tied to a UFO conspiracy.<ref name="Gulyas2015"/>{{rp|quote=For conspiracy researchers like Kenn Thomas, Fred Crisman was a nexus point for a number of conspiracies and cover-ups from the late 1940s until Crisman’s death in 1975|pp=30–31}}
