( CNN ) -- John Lennon 's killer , Mark David Chapman , is up for parole for the sixth time , just months short of the 30th anniversary of the former Beatle 's death . Chapman is scheduled to be interviewed by two members of the parole board during the week of August 9 . Four letters were submitted against Chapman 's release this year , according to a representative of the New York State Division of Parole , and there were two letters in support . The last time Chapman was up for parole , in 2008 , the New York State Division of Parole issued a release saying Chapman 's request was denied `` due to concern for the public safety and welfare . '' He also was denied parole in 2000 , 2002 , 2004 and 2006 . Chapman , 55 , is serving a sentence of 20 years to life in prison for the shooting death of Lennon outside Lennon 's New York City apartment on December 8 , 1980 . He has served 29 years of his sentence at the maximum-security Attica Correctional Facility , where he is held in a building with other prisoners who are not considered to pose a threat to him , according to officials with the state Department of Correctional Services . He has his own prison cell but spends most of his day outside the cell working on housekeeping and in the library , the officials said . For the past 20 years he has been allowed conjugal visits with his wife , Gloria . The visits are part of a state program called `` family reunion '' that allows inmates to spend up to 44 hours at a time with family members in a special setting . Inmates must meet certain criteria to receive the privilege . Chapman has not had an infraction since 1994 , said Erik Kriss , spokesman for the Department of Corrections . `` He goes about his business , doing his prison job and without any fanfare , '' Kriss said . Yoko Ono , Lennon 's widow , in previous years has submitted a letter requesting that parole be denied . Attempts to reach Ono 's legal representative and publicist for comment have been unsuccessful .
Mark David Chapman will be interviewed by parole board members in August . In 2008 parole was denied `` due to concern for the public safety and welfare '' but it is not clear if this decision has been appealed.
