PRESIDENT John F. Kennedy was killed by a deadly, high-powered bullet fired by a severely rattled Secret Service agent who discharged his rife in a tragic mistake!

That’s the shocking new theory revealed in a controversial documentary marking the 50th anniversary of JFK’s heartbreaking death in Dallas, which the government pins on Communist sympathizer Lee Harvey Oswald.

According to the new Reelz channel film, “JFK: The Smoking Gun”, set to air Nov. 3, the Commander-in- Chief was REALLY killed by Secret Service agent George Hickey, who was reacting to shots fired by Oswald when his OWN gun went off.

The two-hour flick follows veteran detective Colin McLaren’s four-year probe into the Dallas tragedy. McLaren’s research builds on Bonar Menninger’s book “Mortal Error: The Shot that Killed JFK”, which also fingers Agent Hickey for accidentally firing the fatal shot. In his Reelz TV project, McLaren claims Hickey was out partying the night before JFK was killed – and was not qualified to use the weapon he held while riding in the presidential caravan as it passed through Dallas’ Dealey Plaza on Nov. 22, 1963. Hickey was in the vehicle behind the open limo carrying the 35th President.

Says McLaren, “It was his first time in the follow car, his first time holding the assault weapon he was using.”

It all culminated in mind-numbing disaster, the investigator charges. As shots rang out, Hickey pulled his gun to return fire, the film claims. But when his car stopped suddenly, the unexpected jolt led the agent to accidentally squeeze the trigger on his rife –shooting Kennedy in the back of the head.

HIS bullet was the infamous “second shot” that blew apart the President’s head and changed America forever, McLaren charges.

To further support his scenario, McLaren insists Hickey’s weapon used hollow-point rounds, different than the jacket type of ammunition said to be used by Oswald. Based on their review of forensic evidence, McLaren and Menninger believe Kennedy was struck by a hollow-point bullet. In 1964, the Warren Commission declared Oswald as the lone gunman – though credible evidence suggests he was a fall guy. Two days after Kennedy was killed, the suspected assassin was murdered by Jack Ruby – while in police custody. Lawmen say Oswald – who insisted he was innocent – was never thoroughly interrogated by detectives. And a 1970s congressional investigation concluded the Marine marksman did not act alone.

McLaren and Menninger say their analysis is based on a new review of all the evidence and information related to the case, including thousands of documents released during the Clinton administration in the 1990s.

The two investigators say their fndings show the second shot by Hickey, who died two years ago, was a fatal mistake and nothing more.

“We’re not saying this was intentional,” Menninger says. “This was a tragic accident in the heat of the moment. We don’t suggest he was in any way involved in a conspiracy.”

But there WAS a cover-up, he adds. Menninger claims the government, including JFK’s brother Robert F. Kennedy, sought to keep Hickey and the Secret Service’s involvement under wraps. “Nobody was going to gain,” Menninger explains. 

Former White House aide Roger Stone, whose upcoming book “The Man Who Killed Kennedy” (Skyhorse Publishing) is due out Nov. 4, blasts the documentary as pure fiction.

As The ENQUIRER reported previously, Stone claims power-crazed Lyndon B. Johnson – then JFK’s Vice President – was the mastermind behind a conspiracy to murder Kennedy. Mob-connected nightclub owner Ruby then silenced Oswald before lawmen could fully grill their suspect.

Ruby also had close ties to Johnson and future President Richard M. Nixon, reveals Stone, who worked on the Committee to Re-Elect Nixon in 1972. He then served in the Office of Economic Opportunity during Nixon’s administration.

The evidence revealed by Stone in his book, coauthored with investigative journalist Mike Colapietro, was previously supported by the widowed First Lady, Jackie Kennedy.

“She was convinced that it was her husband’s successor (Johnson) who was the mastermind behind the plot to murder JFK,” a source confided.

Stone feels the concept in the new documentary is “way off the mark.”

“This theory isn’t new and is absolutely ridiculous. This is the latest in the seemingly never-ending attempt to take attention away from the truth.

“My book will show who was really behind the assassination, and it was not this poor Secret Service agent.”
