Mark David Chapman: Where is He Now?

NEW YORK (CBS) John Lennon's killer, Mark David Chapman, is still serving time in a New York prison, 30 years after the former Beatle's death.

He has been imprisoned at the Attica Correctional Facility in Attaca, N.Y., since 1981. Since then, he has been denied parole six times.

The former maintenance man from Hawaii was sentenced to 20 years to life in prison after firing five shots outside Lennon's Manhattan apartment building on Dec. 8, 1980, hitting Lennon four times in front of his wife, Yoko Ono, and others. He pleaded guilty to second-degree murder.

Chapman was most recently up for parole this past September. He recalled at his parole board hearing that he had considered shooting Johnny Carson or Elizabeth Taylor instead, but chose Lennon because the ex-Beatle was more accessible.

"I had a list of people and he was at the top of the list, and he seemed more accessible to me," he said when asked why he chose Lennon. He said Lennon's apartment building "wasn't quite as cloistered" as spots where he could find the others.

Chapman will be eligible again in 2012. Ono has opposed all six of his applications for parole.
