A teacher was beaten to death by her cage fighter boyfriend and suffered 60 injuries in an attack that also left her 15-year-old boy lover seriously injured, a court heard.
Paul Robson, 49, is alleged to have killed Caroline Kayll, 47, at her home in Linton, Northumberland, in November last year after blackmailing her over her sexual relationship with the 15-year-old.
A pathologist at Newcastle Crown Court told jurors Ms Kayll had 60 injuries and died from blunt force to her head.
Robson denies murdering Caroline and denies trying to murder the youth, who had 45 injuries, including stab wounds, slashes, chops and bites.

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.
Jealous ex-convict Paul Robson, 50, ‘carried out a vicious attack on Caroline Kayll, 47, and her teenager lover’
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 jurors were shown pictures of Robson stopping off on his way from Glasgow

Boy did not recognise killer of ex-prison officer lover, court told
The 15-year-old boy who was badly injured as his ex-prison officer lover was murdered downstairs did not recognise her killer, a court heard.
Paul Robson is accused of blackmailing and murdering his ex-partner Caroline Kayll after finding out she was dating a 15-year-old boy, who cannot be identified. The teenager told police he was upstairs at her home in Linton, Northumberland, when he heard banging on the door and Mrs Kayll let someone in.
A man, described by the boy as heavy and a ‘baldie’, came upstairs and attacked him with scissors, he told specially trained police officers. At one point during the struggle the man said ‘don’t move or I will kill you’ before coming back with a knife from the kitchen which he used to stab the boy.
The attacker then made the boy go downstairs where he saw Mrs Kayll lying on the floor, he told officers. ‘He was cutting her hair with scissors, he was standing over her to the side. I can’t remember what he was saying, she wasn’t responding,’ he told police.
The man then got a meat cleaver and hit the boy over the head twice, leaving him dizzy. The boy said the killer sprayed Mrs Kayll with the garden hose and also squeezed ammonia from a bottle over her, and him, before fleeing the scene.
When the officers asked if the boy recognised the man, or if he had ever seen him before, he said no. Robson denies blackmail, murder and attempted murder.
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.
Robson, of Howdon, Wallsend, denies murder, attempted murder and blackmail.
The trial continues.
Murder victim worked hard for her lifestyle, estranged husband says
Murder victim Caroline Kayll had worked hard for her ‘good lifestyle’, her estranged husband told jurors.
The 47-year-old had previously worked as a social worker, a police officer in Cumbria, a prison officer, took on a teaching role behind bars, then moved to 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 manager.
They remained on good terms after they separated, he told Newcastle Crown Court, and would still meet up every few weeks.
He heard a rumour she had been seen with ex-HMP Northumberland inmate Paul Robson, 50, who denies her murder, blackmail and the attempted murder of a 15-year-old boy.
Mr Kayll told the court: ‘I asked Caroline if the rumours were true and she categorically said no and got quite upset I had asked her.’
He told the court she had done well in her new role teaching in a school, swiftly gaining a promotion.
‘She really enjoyed her job working with the children and got on well with the staff,’ he said.
A keen horse-rider, she had two horses at a farm two miles away and a border terrier called Boxer who was always by her side, Mr Kayll said.
She owned her own home, he said, adding: ‘Caroline had a good lifestyle, she worked very hard for what she had.’
Mr Kayll said they shared the profits when they sold their marital home.
The court has heard Robson blackmailed her about her relationship with the boy and that after paying him £29,000, she was left with ‘precious little’ savings.
Mr Kayll said she wanted to meet him, which he had agreed to do, but she cancelled and when he asked what she had wanted to discuss, she replied ‘money’.
Mrs Kayll was friendly with Neil Welsh, who worked at the farm where she stabled her horses and they spoke regularly, he told the court.
Mr Welsh said she confided in him that after she split up from Robson, she was seeing someone much younger, claiming he was 18.
Mr Welsh told the court: ‘I had a joke about it at the time and said my daughter was the same age, but you see younger people and older people on the telly all the time, but he was old enough so I didn’t hold a grudge.’
She had had cancer, had undergone a hysterectomy and could not have children, the court heard.
Jury hears about cagefighter background of murder accused
Murder accused Paul Robson’s background as a cagefighter could help the jury decide what happened, the prosecution said.
Newcastle Crown Court was shown two photos of the 50-year-old fighting in the ring and was told he was experienced in mixed martial arts (MMA).
The former convict, from Stanley Street, Wallsend, North Tyneside, denies murdering his ex-partner Caroline Kayll at her home in Linton, Northumberland, and the attempted murder of a 15-year-old boy she had started seeing.
Nicholas Lumley QC, prosecuting, told the jury about Robson’s CV which spoke of his gym work and how he delivered fitness programmes, and mentioned his email address which started ‘cageconditioningcoach’.
Mr Lumley said: ‘There is nothing wrong in being physically fit, nothing illegal about MMA, but his sporting prowess and his strength, on which he had worked for many years, may be relevant when you come to consider any of the issues raised in their case.’

When Robson was arrested in Glasgow, he was ‘belligerent’ with Northumbria Police officers who went to collect him, demanding they give him back his spectacles which had been seized, Mr Lumley said.
The jury was shown a video of Robson shouting at officers: ‘Don’t think I’m some sort of mug, I have been here before.’
He did not answer detectives’ questions but gave a prepared statement which said he was ’emotionally spent’ and was finding it difficult to concentrate.
‘I cannot believe Caroline’s dead,’ he said. ‘The whole thing is like a nightmare, like a bad dream. I’m so tired and I am devastated.’
Robson said he went to her house and they argued. ‘Then I was hit from behind on my head and back and then I fell forward.
‘I recall feeling something around my throat. I remember feeling dazed, sick and scared. I felt like everything was unravelling.’
Robson said he left and contacted his solicitor when he learned she had died.
‘In all the circumstances I am not in a position to sensibly answer any questions,’ the statement concluded.
James Mulholland QC, defending, said Robson had grown cannabis at his flat and was drying it in Mrs Kayll’s garage.
He also possessed a number of expensive designer watches which he kept at their former home.
Mr Mulholland suggested to Mrs Kayll’s friend, Neil Welsh, that this explained why Robson was asking for money from her, as she had disposed of the drugs and watches. Mr Welsh denied the suggestion.
