This December marks the 30th anniversary of that fateful Dec. 8 night when deranged fan Chapman walked up to Lennon and Ono outside the couple’s home in New York City’s The Dakota and fired five bullets at the former Beatle, four of which hit Lennon’s shoulder and back. Lennon died later that evening at St. Luke’s-Roosevelt Hospital Center.

Sentenced to 20-years-to-life, Chapman is currently serving his time in Attica prison, and is scheduled to make his sixth appearance before the parole board during the week of Aug. 9, according to the New York Daily News.

As in past parole proceedings, Ono has sent a letter to the board opposing Chapman’s release. The Daily News notes that it is not known whether Ono pens a new letter for each parole hearing or if she just resubmits the original letter. However, the newspaper did print an excerpt from her original letter submitted in 2000, the year Chapman first appeared before the board.

“I am afraid it will bring back the nightmare, the chaos and confusion once again,” Ono wrote in 2000. “Myself and John’s two sons would not feel safe for the rest of our lives.”

Ono also speculated that Chapman, if released, would not be safe on the streets.

How is Chapman coping with prison life? The Daily News reports he cleans up offices and assists inmates in one of the prison’s law libraries. He also receives conjugal visits from his wife about once a year.

Evidently, no one is expecting Chapman to be released. The newspaper quoted Robert Gangi, head of prisoner rights group Correctional Association of America, saying he doubts Chapman will ever be paroled.

“Given that he committed a high profile crime and he killed one of the most famous and most beloved figures literally in the world, it’s highly unlikely three parole commissioners would vote to grant him release,” Gangi said.
