The world was stunned when the Beatles singer, John Lennonwas murdered in New York’s Central Park West in 1980.

Lennon was returning to the apartment he shared with his wife, Yoko Ono, when he was shot and killed by what everyone assumed was Mark David Chapman. However, British author and TV presenter, David Whelan, now believes that Chapman may actually be innocent of the murder.

His upcoming documentary and book describes how there may have been a second executioner. Whelan’s book is called Gimme Some Truth – The Assassination of John Lennon and he told the New York Post that there is a lack of truth in the story that Lennon was shot from behind by Chapman.

The author believes he was shot in the chest from the front by a professional hitman, not Chapman, who is said to have been within 25 meters of Lennon when he fired. The author spoke with the surgeon, Dr. David Halleran, and the two nurses, Barbara Kammerer and Dea Sato, who did everything they could to save Lennon when he was taken to the hospital.

Dave Wedge, who co-authored a book called ‘The Last Days of John Lennon’ believes there is no truth to Whelan’s theory. “It’s a fantasy,” Wedge said of the new theory. “We searched all the files of the cases that had not been examined for 30 years. No one disputes that Chapman was the perpetrator. He has repeatedly confessed and apologized.”

Chapman pleaded guilty to murdering John Lennon. He is serving his sentence at the Green Haven Correctional Institution in upstate New York.
