The decision not to release 57-year-old Mark was made during a hearing on Wednesday.
“Despite your positive efforts while incarcerated, your release at this time would greatly undermine respect for the law and tend to trivialize the tragic loss of life which you caused as a result of this heinous, unprovoked, violent, and calculated crime,” board members Joseph Crangle, Marc Coppola and Sally Thompson told Chapman.
They also told Chapman before making their decision they did take into consideration his “good conduct, program achievements, educational accomplishments, positive presentation, remorse, risk and needs assessment and letters of support.”
Chapman, who has been in front of the parole board seven times, is illegible to go before the board again in two years.
Chapman killed the former Beatle singer in December 1980 outside his Manhattan apartment building.
Lennon was 40 at the time of his death. His wife Yoko Ono, who was with him when he was murdered, was at the parole hearing. She has been to all seven.
