Despite Chapman's regret, the parole board denied his request for parole.
"You shot and killed an innocent victim, an international music star," the New York State Board of Parole wrote to Chapman. "Your actions clearly demonstrated a callous disregard for the sanctity of human life."
The parole board noted that Chapman's record does not have any prior convictions and that they took into consideration his good conduct in prison, educational accomplishments, his remorse, letters of support and "significant" opposition to his release.
But the board decided that "parole shall not be granted for good conduct and program completions alone."
"Therefore, 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, cold and calculated crime," the board wrote.
Yoko Ono, the wife of the late musician, said in 2010 that she opposed paroling Chapman and believed he could be a danger to her and her family.
Chapman became eligible for parole on Dec. 4, 2000, according to the New York Department of Corrections.
The Department of Corrections released an updated photo of Chapman that was taken on May 15, 2012. Chapman's next scheduled parole hearing will be in August 2014.
