MANHATTAN — John Lennon’s murderer Mark David Chapman was denied parole on Tuesday for the sixth time, the Associated Press reported.
The parole board reportedly wrote Chapman they denied his request because of "the disregard you displayed for the norms of our society and the sanctity of human life when, after careful planning, you travelled to New York for the sole purpose of killing John Lennon."
Chapman, 55, shot the ex-Beatle on December 8, 1980, outside of Lennon’s home at the famed Dakota building on Central Park West.
Chapman was sentenced to 20 years to life for second-degree murder.
In 2008, during Chapman's last parole hearing, he told the panel he was sorry for what he had done and explained he had been seeking notoriety and fame to counter feelings of failure, according to the AP.
Chapman next comes up for parole in 2012.
