Victim: Mitchell Harrison died in a brutal manner
"Psychopath": Murderer Nathan Mann
Scene: The gruesome killing shocked Frankland prison workers
Two prisoners who sliced open another inmate to eat his liver have been told they will spend the rest of their lives in jail.
Sadist Michael Parr, 33, and double murderer Nathan Mann, 23, attacked rapist Mitchell Harrison to prove themselves as hard men.
They dragged him into his cell where they covered his mouth to silence his screams and proceeded to disembowel him in a medieval torture which shocked even the most hardened of guards in Durham’s Frankland jail.
The pair had “fantasised” about cannibalism and intended to share Harrison’s liver - but could not bring themselves to try it once he was dead.
As they were both jailed for life for the attack at Newcastle crown court yesterday, sources on the inquiry revealed the evil pair had shown not a flicker of remorse in the aftermath of the barbaric murder.
Instead, the main motive for doing was apparently to increase their reputation as prison hard men.
One source told the Mirror: “Mann in particular is a very disturbed individual. He told in vivid detail how he tried to kill Harrison but said ‘it was not as easy as you think’.
"He initially attempted to put a pen into his skull through his eye but said that had not killed him and made him struggle all the more.
"He then set about disembowelling him and he recalled how hard it had been to keep him down even when he thought he was dead.
"He was completely cold, unemotional, and without any remorse. He could have been describing a trip to the shops.
"When asked why he had done it, he gave no real reason.
"He did not like Harrison but he had not crossed him in any way, he just thought he was a bit cocky.
"We believe he wanted to enhance his reputation with other inmates.”
Parr, who admitted murder, was more concerned about privileges he might lose due to his enhanced “AAA” security status following the attack.
Mann pleaded guilty to manslaughter due to diminished responsibility.
He was already serving life for murdering two elderly women. He has never given the reasons for the double murder.
Both men were told they will never be freed, such is their danger to society.
Sentencing at Newcastle Crown Court, Mr Justice Openshaw said: “I consider this to be a murder of peculiar and unusual brutality.
"Because of the risk these prisoners pose I cannot envisage the circumstances where either of them are ever released.
"They will face the fact that they may well end their lives in prison.”
Mann was described as a “classic cold, callous and homicidal psychopath”.
He had harboured fantasies about killing and of cannibalism, and planned to live out his twisted urges in the murder.
The pair had talked about consuming their victim’s liver and targeted Harrison, who was at the time serving at least four-and-a-half years for the rape which happened in Kendal, Cumbria, because they believed he was "arrogant”.
On the morning of October 1, 2011, Parr and Mann had lured Harrison’s into Mann’s cell before launching the brutal attack.
Mann attempted to strangle him and then stabbed him in the eye with a biro pen, before slashing his neck with a weapon made from plastic cutlery and razor blades.
As Mann inflicted the gruesome attack, Parr held the victim down by his legs.
Harrison’s abdomen was then cut open exposing his small intestine, but despite their initial plans to remove the victim’s liver, they were “unable to go through with it”.
There was no suggestion that the deceased’s liver had been removed, the court heard.
Robert Smith QC, prosecuting, told the court: “Officers went to check the cell and found the deceased lying on the bed.
"Nathan Mann reported that they had just killed someone.
"The defendant said he had wanted to kill someone and that they did not really like the victim and he had appeared arrogant.
"There was a large open wound to the left side of the deceased’s neck.
His abdomen was exposed, his small intestine was protruded.”
Mann was serving a life sentence with a minimum of 24 years for the vicious murder of two woman aged 72 and 56, at a nursing home in Leicestershire, in 2010.
Parr was serving a life sentence in 2003 for the attempted murder of a patient in a psychiatric hospital.
In interviews with police after the attack, Parr said he was “excited” that he found someone in Mann with whom he shared a common interest.
Mr Smith QC told the court that prior to Harrison’s death, Mann had warned prison staff that he would kill someone, but that these had been dismissed as threats.
A note written by Mann was also discovered after the attack, which outlined his reasoning for wanting to kill someone.
Mr Smith QC said: “The investigation into the death revealed Nathan Mann had written a note.
"He had described he did not have the guts to kill himself but did have the guts to kill someone else.
"He could not handle the fact that he had killed two vulnerable people.
"He said in the note he could not handle the voices in his head and the belief that someone was going to kill him.
"He said killing someone was the only way he thought he would be segregated from everything.”
Similarly before the incident, Parr had told a psychiatric nurse that he had fantasies of chopping off fellow prisoners’ heads and cutting open their stomachs.
During the sentence, a doctor’s report on Mann was read out, which described him as possessing compulsive homicidal urges.
Parr was sentenced to life imprisonment with a minimum of 32 years.
Mann was sentenced to life imprisonment with a minimum of 16 years on top of his current sentence.
Their victim Harrison, originally from Wolverhampton, was jailed in January 2010 after he admitted raping an under age girl.
He was 21 at the time of the attack.
He admitted two counts of rape at Carlisle Crown Court, where he received an indeterminate sentence and was put on the sex offenders’ register for life.
His family said in a statement after his murder: “He was a much loved son and brother and we are devastated by his death.
"Although we never condoned his past actions, he was by all accounts a model, trusted prisoner who did not deserve to die in this horrific way.”
