An Ohio man who killed his roommate in 1978 and ate part of his brain has been denied parole for a fifth time.

A prisons spokeswoman says the Ohio Parole Board concluded 60-year-old inmate David Allen Chapin is "unsuitable for release." The Cincinnati Enquirer (http://cin.ci/1TFubZx ) reports he will next be considered for parole in December 2018.

Chapin is serving life at a prison in Lima (LY'-muh) for shooting his longtime friend Donald Liming in the eye during a dispute over religion. The then-23-year-olds shared an apartment in Milford, in southwest Ohio.

Chapin told a court-ordered psychiatrist that he ate Liming's brain as part of a "mutual agreement" between the friends.

Liming's family continues to argue for keeping Chapin incarcerated. The Clermont County prosecutor says his office strongly supports that position.
