Chapman fired five shots at Lennon on December 8, 1980 outside of Lennon's Manhattan apartment. Less than a year later, Chapman was sentenced to 20 years to life after pleading guilty to second-degree murder.
Since 2000, Chapman has been up for parole every two years.
The parole board wrote to the 59-year-old Chapman, "you would not live and remain at liberty without again violating the law...This victim had displayed kindness to you earlier in the day, and your actions have devastated a family and those who loved the victim."
The board is referencing the fact that hours before killing him, Chapman asked for Lennon's autograph. Lennon agreed.
