Two prisoners who disembowelled a fellow inmate at Durham's Frankland Prison have been given life sentences.
Mitchell Harrison, 23, originally of Wolverhampton, was serving an indefinite term for child rape in Cumbria when he was killed in October. Michael Parr, 32, and Nathan Mann, 23, cut his neck with a scalpel made from plastic cutlery and a razor blade.
Newcastle Crown Court heard they cut the dead victim's stomach and planned to eat his liver, but did not do so. Parr had earlier pleaded guilty to murder and must serve a minimum term of 32 years. He was already serving life for the attempted murder of a hospital patient.
Mann pleaded guilty to manslaughter on the grounds of diminished responsibility and was sentenced to life with a minimum term of 16 years, to run consecutively to the 24-year minimum sentence he is already serving for a double murder.
Harrison was jailed in January 2010 after he admitted raping a 13-year-old girl in Kendal, Cumbria. He was killed in his cell at the category A facility, which has housed some of the UK's most high profile and dangerous inmates.
Sentencing the pair for the "ghastly and gruesome" killing, Judge Justice Openshaw said: "I can't envisage circumstances in which either of them will ever be released. "They will face the fact that they may well end their lives in prison."
Mitchell Harrison's family said in a statement: "Our lives have been shattered by Mitchell's horrific murder. His death was cruel and unnecessary."
