John Lennon's killer has been denied parole for a 10th time and will remain behind bars for at least two more years.

Mark David Chapman appeared before New York's parole board on Wednesday. In a denial decision obtained Thursday by The Associated Press, the board said it had determined Chapman's release "would be incompatible with the welfare and safety of society and would so deprecate the serious nature of the crime as to undermine respect for the law."

Chapman, 63, shot and killed the former Beatle outside Lennon's Manhattan apartment on Dec. 8, 1980. He is serving 20-years-to-life in the Wende Correctional Facility in western New York.

"You admittedly carefully planned and executed the murder of a world-famous person for no reason other than to gain notoriety," the parole panel wrote in its denial decision.
