Newly released John F. Kennedy assassination files include details from the eerie 'suicide' of the CIA insider who blamed the agency for the 35th president's death in 1963.
CIA informant and former US Army Captain John Garrett Underhill Jr., commonly known as Gary Underhill, was found shot dead in his Washington apartment six months after JFK was killed.
The coroner declared Underhill had killed himself - but conspiracists have long thought otherwise since he had accused the CIA of being responsible for the fatal event.
One of the 80,000 investigative documents published by the National Archives on Tuesday revealed chilling details about Underhill's pre-mortem confessions, as well the suspicious circumstances of his death.
The memo - titled Ramparts: John Garrett Underhill Jr., Samuel George Cummings, and Interarmco - described Underhill as a WWII intelligence agent who was 'on intimate terms with many of the top brass in the Pentagon.'
Underhill was known during his time as an intelligence agent as a 'recognized authority on limited warfare and small arms,' the memo said.
Given his closeness with the CIA, he was reportedly one of the agencies go-to people to embark on special assignments.
The day after the assassination, Underhill reportedly rushed out of Washington DC and showed up at his friend's New Jersey home late in the evening.

'He was very agitated,' the filing revealed.
'A small clique within the CIA was responsible for the assassination, he confided, and he was afraid for his life and probably would have to leave the country.'
Underhill was depicted by his peers as 'sober but badly shook,' according to the memo.
'They say he attributed the Kennedy murder to a CIA clique which was carrying on a lucrative racket in gun-running, narcotics and other contraband, and manipulating political intrigue to serve its own ends,' the document continues.
His friends alleged JFK 'got wind that something was going on' but was murdered before he could do anything about it.
Underhill was reportedly a rational and level-headed individual. At first, his friends were not convinced of his accusations against the CIA.
One said, as per the files: 'I think the main reason was...that we couldn't believe that the CIA could contain a corrupt element every bit as ruthless - and more efficient - as the mafia.'
The memo also included the perspective of Underhill's writing collaborator Asher Brynes, who was the one who discovered his dead body.
President Donald Trump said on Monday that 80,000 pages of JFK files would be released the on Tuesday
He was shot behind his left ear, which was 'odd' given he was right handed, Brynes said.
Another detail that may allude to an unsettling connection is Underhill was allegedly a friend of Interarmco founder Samuel Cummings.
Interarmco was the arms broker for the CIA, as well as Klein's Sporting Goods in Chicago - the store Lee Harvey Oswald allegedly mail-ordered the Carcano rifle he shot JFK with.
JFK investigative documents were published by the National Archives on Tuesday after the White House said Americans would be 'shocked' by the information.
'We are tomorrow announcing and giving all of the Kennedy files...people have been waiting for decades for this,' Trump said on Monday. 'We have a tremendous amount of paper. You've got a lot of reading.'
He added: 'I don't believe we are going to redact anything. I said just don't redact. You can't redact. But we're going to be releasing the JFK files.'

Despite this claim, some pages are heavily redacted with thick black bars across the pages.
'It's a lot of stuff, and you'll make your own determination,' Trump said of the contents, adding that he saw them before their release.
Since their release, conspiracy theorist skeptical of the circumstances of JFK's death - including Oswald being the assassin - have scoured the documents for any detail from the investigation that proved a different story.
