In London, The Sun is reporting that Mark David Chapman, the man convicted of murdering John Lennon has been having annual sex sessions during conjugal visits with his wife for the last 16 years.

Prison officials have confirmed that Chapman is allowed 44 hours alone with his wife in a private room. The room has no cameras or guards inside, and the conjugal visitation privilege is part of Attica Correctional Facility’s “family reunion” program. Chapman joined the program in 1992.

Chapman is serving a 20-to-life sentence in Attica after being convicted of shooting John Lennon outside of the former Beatle’s home at the Dakota building in New York back in December of 1980.

Since his imprisonment, Chapman has made four bids for parole and has been denied each time. He is currently preparing for another bid at freedom, claiming that the mental illness that led to him killing Lennon is a condition he no longer suffers from.
