A decades-old video could shed new light on a conspiracy theory regarding the assassination of the late US president John F. Kennedy.
On November 22, 1963, the US was rocked with the new that Kennedy, the 35th President of the United States, had been killed in front of crowds of people while waving to them from his open-topped car in Dallas, Texas.
Kennedy, 46, was shot once in the back, with the bullet exiting via his throat, and once in the head and was pronounced dead 20 minutes later at Parkland Hospital.
Lee Harvey Oswald was arrested for the killing, however, he denied being the shooter, and was himself shot and killed just two days later.
Though Oswald was killed before he could be prosecuted, the Warren Commission report later concluded that Oswald acted alone and was responsible for the shocking killing.
Kennedy's death sparked a lot of conspiracy theories, with many questioning whether Oswald did in fact act alone to cause the level of injuries the president died from.
Kennedy's autopsy also raised questions about how one bullet could cause so much damage, leading many to believe there may have been multiple shots from more than one gunman.
Footage of the fateful moment, taken by Orville Nix, an air conditioner repairman, which has not been seen since 1978 could hold the key to solving the mystery.
The grainy 8mm footage was taken from the grassy knoll where some witnesses believe the shots originated from.
Conspiracy theorists have also claimed a second gunman may have been hiding behind a fence on the knoll.
The footage was sent for analysis by a Los Angeles company and later fell under federal ownership, but they have claimed they no longer have it.
Nix died in 1972, and his son launched a legal battle to recover the footage - claiming it could be worth up to $900 million - which Nix's granddaughter, Linda Gayle Nix Jackson, has now picked up following her own father's passing.
The footage could hold the answers to the questions surrounding Kennedy's death, with Scott Watnik of Wilk Auslander LLP, acting on behalf of Nix Jackson, claiming advancements in technology could help the footage to be made clearer.
He told the New York Post: "It’s really the only one that is known to have captured the grassy knoll area of Dealey Plaza right as the assassination occurs.
"If we subjected the camera-original film to optics technology of 2026, we can certainly capture details in the film that we never could have captured when … the committee had the film in 1978."
He added that the footage could support a 1978 House Select Committee on Assassinations report that found Kennedy "was probably assassinated as a result of a conspiracy".
A federal judge has now ruled that legal proceedings to recover the film can go ahead, meaning the footage could soon see the light of day once more.
