A team of historians and retired Secret Service officers led by historian Max Holland has used new technology to categorically confirm in their minds the judgement that Lee Harvey Oswald acted alone when he killed John F. Kennedy 48 years ago.

Max Holland, who has investigated JFK’s assassination moment for years, led a team which digitally enhanced a number of home videos taken on November 22, 1963.

Max Holland’s team studied Abraham Zapruder’s famous footage as well as many other lesser-known films, and brought them all together for the first time to establish a narrative more clear than ever before.

The team will present their findings in documentary “JFK: The Lost Bullet” on the NatGeo channel this Sunday at 9:00 p.m. ET.

Max Holland told Fox News:

“I’d say a main thrust of it is to break the stranglehold that the Zapruder film has on our perception of what happened.”

“In a sense, we’ve all been <<Zaprudered>>. The film was so graphic, disturbing, mesmerising, that it became more of our perspective on the assassination than even the perspective of the assassin, which should never have happened.”

The group also discovered, in the amateur footage taken that day by Robert Hughes, a shadowy figure moving on the sixth floor of the Texas School Book Depository building – a person believed to be Lee Harvey Oswald.

Lee Harvey Oswald was an employee at the Texas Schoolbook Depository, which overlooked the motorcade.

Contemporary investigators found that in March 1963, Lee Harvey Oswald, using the alias “A. Hidell”, purchased a 6.5mm Carcano Model 91/38 rifle by mail order. It is widely agreed this was the gun which killed John F. Kennedy.

Max Holland told Fox News: “Our conclusion is that he fired three shots in about 11 seconds, which is almost double the <<Six Seconds in Dallas>> meme that most people know when they think about the assassination: six seconds, three shots in six seconds.

“We say three shots in 11 seconds, which is a much easier – for I’d say, someone of Oswald’s skill – effortless task.”

President John F. Kennedy was assassinated as he travelled in an open-top car in a motorcade through Dallas. Texas Governor John Connally was also injured.

Within two hours, Lee Harvey Oswald was arrested for the murder of a policeman, then early the next morning he was charged with assassinating JFK.

On the morning of November 24, nightclub owner Jack Ruby shot and killed Lee Harvey Oswald as he was being transferred to the county jail.

There have been numerous conspiracy theories around JFK’s death, with everyone from the American Mafia and the KGB to FBI director J. Edgar Hoover and sitting Vice President Lyndon B. Johnson accused of involvement.

Each theory and every year hundreds of sceptics flock to the site to discuss the latest developments and pay their respects.

When asked by Fox News if there are any “holy grails” of JFK assassination research still not investigated, Max Holland cited Lee Harvey Oswald’s tax returns, which have never been released.

It is widely believed that Lee Harvey Oswald shot three bullets from his rifle. One missed entirely, a second hit John F. Kennedy and passed through Governor John Connally, the third was the fatal shot to the President.

Through FBI testing it was established the gun could be fired by an experienced shooter three times within five to eight seconds.

But in Governor John Connally’s own words: “There were either two or three people involved, or more, in this — or someone was shooting with an automatic rifle.”

John Connally’s wife believed that her husband was hit by a bullet that was separate from the two that hit Kennedy.

In the Zapruder film, the JFK’s head appears to move backwards after the last, fatal shot, an indication to some that a bullet was fired from the front.

There have been witness statements that two men were seen on top of a grassy knoll to the west of the Texas School Book Depository before the shooting.
