Mark Chapman is serving 20 years to life for murdering the Beatle in 1980

The parole hearing for John Lennon‘s killer Mark Chapman has been postponed.

Due to take place this week (beginning August 9), the hearing is Chapman‘s sixth bid for freedom since 2000.

He is currently serving 20 years to life for fatally shooting the Beatle outside his New York home in December 1980.

As the Associated Press reports, Chapman was told about the postponement on Tuesday (August 10), with the parole board stating that they were “awaiting the receipt of additional information so that the record is complete for Mr. Chapman‘s upcoming parole interview”.

Chapman, who has had a clean prison record since 1994, will now have his appeal reviewed in September.

Meanwhile, Lennon’s widow Yoko Ono has written to the parole board opposing Chapman’s possible release.
