Cage fighter, 50, GUILTY of beating his teacher girlfriend, 47, to death over affair with boy, 15
Paul Robson, 50, was in breach of his prison licence when he murdered his ex-partner
A cage fighter on the run from the authorities evaded capture to murder his teacher ex-girlfriend and try to kill her 15-year-old schoolboy lover – after blackmailing her over the illegal affair.
Paul Robson, 50, subjected former partner Caroline Kayll, 47, to an horrific 60 injuries during the attack in her home in Linton, Northumberland, last year.
He overpowered Caroline, knocked her to the floor and then repeatedly kicked her in the head causing the fatal injuries.
Robson then took a pair of scissors to her lifeless body and cut off her hair, before he turned his attention to the teenage boy.
He was stabbed and bitten 45 times but somehow survived the murder attempt.
It was a tragic end to a Robson and Kayll’s relationship, which had begun when they began a secret affair when he was serving ten years for drugs and firearms offences and she was working as a prison teacher.

After he was freed on licence they moved in together, but after they split up he found out about her illegal activities with the child and began blackmailing her for £29,000.
Robson should not have been free to kill after he was recalled to prison in March 2019 because he breached his release terms, but the authorities could not find him.
Instead Newcastle Crown Court were told he travelled from Glasgow to her home, where the jury heard he murdered Mrs Kayll and severely injured the teenage boy in November 2020.
Robson, of Wallsend, North Tyneside, had denied murder, attempted murder and blackmailing his ex-partner, and lied he was attacked by the youth in Mrs Kayll’s home.
The case had featured a series of agreed facts read out by the prosecution.
Barrister Richard Bennett told the court Robson was jailed in 2014 for a total of 10 years for drugs and firearms offences, and that while at HMP Northumberland he gained ‘trusted’ status and worked in the education department, where Mrs Kayll was a teacher.

It is said he drove for three hours from Glasgow to Linton, having bought a locksmith’s bar, a magnetic GPS car tracker, screwdrivers, pliers, a wrench and ammonia

He was released on licence in November 2018, but was then recalled to prison in March 2019 because he had breached his licence, the court heard.
‘Following this, Paul Robson was unlawfully at large,’ Mr Bennett said.
After the murder police found an electronic copy of Robson’s CV on a memory stick, in which he said he was a ex-professional fighter and amateur powerlifter who wanted to become an assessor and verifier.
The court heard Ms Kayll had met her husband Ian Kayll in 2002 after she started work at HMP Northumberland, where he was a manager.
They remained on good terms after they separated and would still meet up every few weeks.
Giving evidence he admitted he had heard rumour she had been seen with Robson, but she denied the relationship.
He told the court: ‘I asked Caroline if the rumours were true and she categorically said no and got quite upset I had asked her.

FACT BOX TITLE
Murder victim Caroline Kayll told “white lies” about the illicit relationship she had with a prisoner and the illegal one she started with an underage boy, jurors heard.
The 47-year-old, married at the time to a senior prison officer, started a clandestine relationship with Paul Robson when he was serving at HMP Northumberland where she taught.
She had previously worked as a social worker, a police officer in Cumbria, a prison officer, took on a teaching role behind bars, then moved into a school role, Newcastle Crown Court heard.
She met her husband Ian Kayll in 2002 after she started work at HMP Northumberland, where he was a security manager.
Robson was to claim he had a secret relationship with her during two jail stints, the second of which continued after he was released.
Mrs Kayll remained on good terms with her husband after they separated and they would still meet up every few weeks.
He heard a rumour she had been seen with Robson and said: “I asked Caroline if the rumours were true and she categorically said no and got quite upset I had asked her.”
After Robson broke up with her, she started an illegal sexual relationship with a 15-year-old boy, claiming he was her godson if anyone asked.
Nicholas Lumley QC, prosecuting, acknowledged she told “white lies” about these illicit relationships and that she had made “some life choices that not all of us in this room would make”.
A keen horse-rider, she had two horses at a farm and a border terrier called Boxer who was always by her side.
She owned her own home and pick-up truck but after paying Robson £29,000 in blackmail after he threatened to expose her, her savings were gone.
Robson was convicted of murdering his ex-partner after a trial at Newcastle Crown Court.
‘She really enjoyed her job working with the children and got on well with the staff.
‘Caroline had a good lifestyle, she worked very hard for what she had.”
A pathologist at the court told jurors Ms Kayll had 60 injuries and died from blunt force to her head.
The boy was found to have suffered 45 injuries, having been stabbed, chopped and slashed, he had bite marks to his arm and defensive injuries to his hands, the court has heard.
Robson claimed in a defence case statement that he was attacked from behind while talking to Ms Kayll.
He said he came round from unconsciousness to find the youth standing over her as she lay motionless on the floor of her house last November.
But pathologist Dr Nigel Cooper, asked if Robson’s injuries match up with Robson’s own account, replied: ‘No they don’t.
‘Usually the victim has injuries worse than the assailant. There’s an enormous discrepancy in the number of injuries between (the boy) and Mr Robson. They are consistent with Robson being the assailant and (the youth) being the victim.’
Dr Cooper told the court Ms Kayll had a ‘catastrophic brain injury’.
As well as multiple areas of bruising to various parts of her head, face, and body, arms and legs, there were cuts to both buttocks. She also had fractures to both cheekbones.
She suffered multiple fractures to her eye socket and nose.
Her brain was found to have been badly damaged by a lack of blood and oxygen. It was also severely swollen, there was nerve fibre damage and a small amount of bleeding.
Referring to the neuropathologist’s report, Dr Cooper said: ‘He says severe force has been applied to Caroline’s head, including an action causing a violent rotational movement of the head.
‘The brain has twisted violently inside the head to cause the fibre damage.’
Referring to causation of the brain injuries, Dr Cooper said a pathologist believes someone kicked or stamped on her head.
He added that it would require a ‘severe’ level of force.
Meanwhile, Dr Cooper said the youth suffered three stab wounds, 19 slashing or chopping injuries, a chop wound to his face with an underlying fracture, seven scratches or similar marks which may or may not have been caused by a sharp weapon and superficial puncture wounds from something used repeatedly, possibly scissors.
The teenager also had four bite marks to his arms and four blunt force injuries.
There were other indistinct injuries and injuries to his hands, including to tendons, which could have been defensive injuries.
Robson claims he was struck from behind while speaking to Ms Kayll.
He said he recalls someone throttling him, doesn’t know how long he was unconscious and he came round dazed.
The statement said he saw the youth standing over Ms Kayll, who was lying motionless on the floor.
His defence statement added: ‘He said he chased (the youth) who ran upstairs. The defendant says (he) was in a rage, calling Caroline a liar and a c*** and he was trying to stab the defendant.
‘At one point he stabbed with such force his hand slipped down the hilt onto the blade.’
The statement went on to say Robson disarmed the youth of the knife but that the youth was in a rage and forced him out of an ensuite bathroom and into the bedroom and that he ended up on top of Robson and was saying ‘she’s a f****** liar’.
It added: ‘He was intent on driving the scissors into the defendant’s face.
‘He bit him and managed to wrestle the scissors from him. He accepts stabbing him a number of times to subdue him.’
The statement went on: ‘The defendant dragged him downstairs. He then went to Caroline Kayll and realised a lot of her hair had been cut off.
‘The defendant attempted mouth to mouth but her mouth was full of blood.
‘He sprayed her face with a hose to clear away the hair and wash away the blood.
‘He tried mouth to mouth and put her in the recovery position.’
Robson then claimed the youth ‘came at him again’ with a meat cleaver but that he got the better of him and disarmed him He accepted he struck him a number of times with the knife but insisted he inflicted the injuries lawfully in self-defence.
Following the case, senior investigating officer at Northumbria Police, Detective Inspector Graeme Barr, welcomed the guilty verdicts.
He said: “This is one of the most violent offences I have investigated in my policing career and I welcome the guilty verdicts of the jury.
“Paul Robson has been fuelled by a jealous rage and attended his former address that night with one thing on his mind.
“His attack on Caroline and his teenage victim was pre-meditated and demonstrated horrendous levels of violence.
“There is no doubt he wanted to kill or permanently disfigure both of his victims. He succeeded in killing his former partner and has left his teenage victim scarred for life.
“Not only that, but he spent the days that followed trying to avoid police before attempting to pin Caroline’s murder on a vulnerable, teenage boy.
“Those actions have put the teenage victim, his family and Caroline’s family through the ordeal of a trial and I want to praise the bravery they have shown throughout these proceedings.
“I know that for them no punishment will be enough, but today’s verdicts do mean that Paul Robson will be handed a life sentence.
“There is a very real chance he will never experience freedom again and I hope that can bring some justice to his victims.”
