He is serving a 20-years-to-life sentence at Wende Correctional Facility in western New York. He pleaded guilty to second-degree murder in 1981, Rolling Stone reported.
Chapman said at previous hearings that he continues to get letters about the pain he caused to fans of the singer. He said in other hearings that he is sorry for choosing the wrong path to fame, the AP reported.
The current parole board told Chapman that releasing him could endanger the public safety because someone may try to hurt him out of anger, revenge, or to gain notoriety for him or herself.
Chapman will be eligible for parole again in August 2020.
He was last denied parole in 2016 and before in 2014 for similar reasons, Rolling Stone reported.
