John Lennon's (search) murderer comes up for parole the first week of October, The New York Post has learned.

Mark David Chapman, (search) now 49 and serving a life sentence in Attica prison for the 1980 murder of the legendary Beatle, has previously been denied parole two times, the last time two years ago.

Parole officials would not classify Chapman's chances of release, but the head of a prisoners rights group said there's virtually no chance he'll get out.

"People like Chapman who committed high-profile violent crimes, no matter what their prison record is like, will never see the light of day as long as the crime is present in our memories, and this one is," said Robert Gangi, executive director of the Correctional Association of New York.

Chapman gunned down the 40-year-old Lennon on Dec. 8, 1980 after he and his wife, Yoko Ono (search), returned to their Dakota apartment building near Central Park (search) after a late-night recording session.

In his two previous parole hearings, Chapman said he doesn't deserve to be released from prison, and cited feelings of "vanity," "jealousy," "anger" and "stupidity" as reasons he wanted to kill Lennon.

A spokesman for Ono, who in the past has said she feared Chapman being back on the streets, yesterday had no immediate comment.
