A man once given a restraining order for stalking supermodel Kate Moss has pleaded guilty to brutally killing his parents.
William Warrington, 42, escaped from a mental health unit to savagely kill dad Clive, 68, and mum Valerie, 73, in March.
Clive’s body was discovered first by police in his flat in Cheltenham, Gloucestershire, raising the alarm about his ex-wife Valerie.
This led police to race 15 miles away to posh Bourton-on-the-Water where they tragically found her dead.
Both had been mercilessly stabbed and beaten to death and suffered horrific injuries.
Warrington even ran over his mother's dead body on the lawn of her house as he drove off to kill his father leaving a tyre mark on her back.
In 2019 Warrington was slapped with a restraining order after leaving 'unwanted items' at the £2.5million Cotswolds home of super model Kate Moss.
A court heard how his sinister actions 'caused distress to Moss and her family and he was banned from going anywhere near her home in order to protect the model, her family and her employees.
But in February Warrington was in trouble again when he was arrested on suspicion of GBH having attacked his house mate with a knife.
He was detained under section 2 of the Mental Health Act and taken to the Priory Ward in the secure unit at Wotton Lawn, Gloucester.
On March 1 he left the unit on escorted leave with a carer and sneakily got £100 cash back at a local petrol station.
Later that evening he was allowed to go for a stroll in the unit's secure courtyard but instead walked straight out of the front door unnoticed to a waiting taxi he had booked.
The alarm was raised at midnight but Warrington was nowhere to be found.
Cunning Warrington got the cabbie to stop at two garages where he stocked up on brandy and red bull before being dropped off at a rural roundabout five miles from his mum's house.
He then went to his mum's isolated house near leafy Bourton-on-the-Water and killed her.
He took a nap, stole her car and drove to to his dad's flat in Cheltenham.
There neighbours were awoken by a commotion downstairs and heard his dad Clive shout: “Help police” and “Why are you doing this?'
They then heard another voice, believed to be Warrington's, shout: “I am going to enjoy this” before it suddenly went silent.
Neighbours then saw a man matching Warrington's description flee the flat covered in blood.
He was arrested a short time later.
This morning Warrington pleaded guilty to killing Clive and Valerie Warrington.
Warrington had denied murder, but pleaded guilty to manslaughter on the grounds of diminished responsibility, after the lesser charge was accepted by the Crown Prosecution Service.
Warrington's brother and sister, in a statement read to the court, said their parents' deaths had been "preventable" and they have "lost all confidence in the government agencies responsible for managing and responding to mental health crises and domestic abuse."
"William's mental health has visibly been in decline for the past decade and the deterioration accelerated due to a deficiency in support for William. As he lost his mind we lost our brother."
In a statement read to the court, his family said: "Our worst nightmares were realised in the crimes that were committed on March 2, 2022.
"We couldn't have foreseen the events of that day, however, weeks prior fears for the safety of the family had been communicated to the emergency services, Gloucestershire police and the NHS care trust at Wotton Lawn hospital.
"Our fears were confirmed when our parents were brutally murdered by our brother… We firmly believe he continues to pose a continued threat to the family. He is being treated at Broadmoor. The idea that he might one day be released is horrifying. We remain living in fear for our safety."
A statement from Gloucestershire Health and Care Foundation read: “The deaths of Clive and Valerie Warrington were both shocking and tragic and we continue to offer our sincere condolences to everyone affected.
“As well as supporting Gloucestershire Police with their inquiry, we are undertaking our own investigation.
“The outcome will be shared with NHS England and the Care Quality Commission who will further scrutinise this as per national requirements.
“Any learning will be thoroughly addressed, however we will not say anything more until the family has been given the opportunity to be fully updated on the findings.”
During the hearing relating to Kate Moss in 2019, magistrate David Kinchin told Warrington: "We are making this restraining order to protect Kate Moss, her family and employees.
"The order will prohibit you from contacting directly or indirectly Kate Moss.
"That includes any form of social media."
According to the Crown Prosecution Service, he left a bottle of champagne, a cake, a fake and a real sunflower, and a World War II metal helmet with what appeared to be a threatening note in it outside Ms Moss' home.
On 12 October 2018 a housekeeper found a Phantom of the Opera style mask on the front gates of the house when she arrived at work.
Whilst he accepted leaving them, he was not convicted of a charge relating to leaving them.
Warrington was told he could not to attend a main road into Little Faringdon.
Mr Kinchin added: "This order is made for an indefinite period.
"If you do any of those things you commit a serious offence for which you
could be sent to prison."
