A teenager who was planning a mass shooting at his old primary school has been jailed for life with a minimum term of 49 years for murdering his family.
Nicholas Prosper, from Luton, pleaded guilty to the murder of his mother, Juliana Falcon, 48, and his siblings, Kyle Prosper, 16, and 13-year-old Giselle Prosper at Luton Crown Court in February.
In sentencing, the judge said the words “heartless and brutal” were insufficient to describe the horror of the last moments suffered by his victims.
Their bodies were found at their flat in the town in September last year.

Prosper, who was planning a mass shooting at his former primary school, was arrested after the phone call.
The 19-year-old planned to carry out a mass shooting at St Joseph’s Catholic Primary School, where Prosper and his siblings had been pupils, he admitted to police.
The court heard his aim was to be known as “the world’s most famous school shooter of the 21st century”.

Police believe he killed his family when his mother found a shotgun he had bought using a fake certificate and confronted him.
His scheme was eventually foiled by officers who spotted him in the street immediately after the murders and arrested him.
The loaded shotgun was found hidden in bushes nearby, along with more than 30 cartridges.

As his sentencing started on Tuesday, the court heard that “his planning was cold, deliberate and without sympathy or emotion towards the actual victims or potential victims”.
Judge Mrs Justice Cheema-Grubb said the details of Prosper’s case were “chilling”, and that he had wanted to emulate and outdo the US school massacres at Sandy Hook in 2012 and Virginia Tech in 2007.
His “main wish”, according to the prosecution, was notoriety, telling a prison nurse “I wish I had killed more”.
Mrs Justice Cheema-Grubb said Prosper had not hated his mother or siblings and had “had a good life with them”, but that his intention had been to kill them in their sleep and rape his sister.
“Each victim suffered the anguish of anticipating or being aware of the deaths of others,” she said.
In explaining why she had opted not to impose a whole-life sentence, the judge said: “A minimum term does not in any way equate to the value of the life of a murder victim, still less three such victims.”
She acknowledged that Prosper had autism spectrum disorder, but said she was satisfied that it did not affect his decision-making enough to be the primary reason why he carried out the killings.
“A murder spree with the sole aim of glorifying the name of the perpetrator in the history of mass killers is what you intended,” she said.
“You have also expressed no remorse and no sorrow. Indeed, when asked by the psychiatrist if you would try to commit another massacre, you replied: ‘Well, that’s their job to stop me getting the weapons if I get released’.“
Mrs Justice Cheema-Grubb added: “Your plans were intelligent, calculated and unselfish. Your ambition was notoriety. You wanted to be known posthumously as the world’s most famous school shooter of the 21st century.
“Words such as heartless and brutal are insufficient to describe the horror of those last moments of the people who were closest to you.”

Officer DCI Sam Khanna says the Nicholos Prosper case is the most ‘distressing’ he’s ever worked on.
A statement from the family of the victims was read outside the court.
It said they now understood the deaths had “much more meaning and importance” because they “stopped any other family in the community going through the pain we have suffered”.
“For now, we would ask people to remember Juliana, Kyle and Giselle for the people they were. Julie was a strong, loving mother to her four children, who were her absolute world.
“Kyle was a kind and funny young man who loved football and boxing. He was a big talent with massive potential. Giselle was a beautiful soul and caring young girl with an infectious smile. She was also an exceptional pupil at school and was loved dearly by her friends.”
Manchester Arena bomb plotter Hashem Abedi has been charged with three counts of attempted murder.
It comes after four prison officers were injured in an attack at the maximum security prison HMP Frankland in Co Durham on 12 April.
Abedi has also been charged with one count of assault occasioning actual bodily harm and one count of unauthorised possession of a knife or offensive weapon.
Counter Terrorism Policing North East has said it carried out a “thorough investigation” of the incident with Durham Constabulary and HMP Frankland.
He remains in prison and is due to appear at Westminster Magistrates’ Court on 18 September.
Three prison officers were taken to hospital with serious injuries following the incident.
Marnie’s first serious relationship came when she was 16-years-old.

She was naturally excited when a former friend became her first boyfriend.
But after a whirlwind few months, everything changed with a slow, determined peeling away of her personality.
“There was isolation, then it was the phone checking,” says Marnie.
As a survivor of abuse, we are not using her real name.
“When I would go out with my friends or do something, I’d get constant phone calls and messages,” she says.
“I wouldn’t be left alone to sort of enjoy my time with my friends. Sometimes he might turn up there, because I just wasn’t trusted to just go and even do something minor like get my nails done.”

He eventually stopped her from seeing friends, shouted at her unnecessarily, and accused her of looking at other men when they would go out.
If she ever had any alone time, he would bombard her with calls and texts; she wasn’t allowed to do anything without him knowing where she was.
He monitored her phone constantly.
“Sometimes I didn’t even know someone had messaged me.
“My mum maybe messaged to ask me where I was. He would delete the message and put my phone away, so then I wouldn’t even have a clue my mum had tried to reach me.”
The toll of what Marnie experienced was only realised 10 years later when she sought help for frequent panic attacks.
She struggled to comprehend the damage her abuser had inflicted when she was diagnosed with PTSD.
This is what psychological abuse and coercive control looks like.

‘His hands were on my throat – he didn’t stop’
Young women and girls in the UK are increasingly falling victim, with incidents of domestic abuse spiralling among under-25s.
Exclusive data shared with Sky News, gathered by domestic abuse charity Refuge, reveals a disturbing rise in incidents between April 2024 and March 2025.
Psychological abuse was the most commonly reported form of harm, affecting 73% of young women and girls.
Of those experiencing this form of manipulation, 49% said their perpetrator had threatened to harm them and a further 35% said their abuser had threatened to kill them.
Among the 62% of 16-25 year olds surveyed who had reported suffering from physical violence, half of them said they had been strangled or suffocated.
Earlier this year, Sky News reported that school children were asking for advice on strangulation, but Kate Lexen, director of services at charity Tender, says children as young as nine are asking about violent pornography and displaying misogynistic behaviour.

“What we’re doing is preventing what those misogynistic behaviours can then escalate onto,” Ms Lexen says.
Tender has been running workshops and lessons on healthy relationships in primary and secondary schools and colleges for over 20 years.
Children as young as nine ‘talking about strangulation’
Speaking to Sky News, Ms Lexen says new topics are being brought up in sessions, which practitioners and teachers are adapting to.
“We’re finding those Year 5 and Year 6 students, so ages 9, 10 and 11, are talking about strangulation, they’re talking about attitudes that they’ve read online and starting to bring in some of those attitudes from some of those misogynistic influencers.
“There are ways that they’re talking about and to their female teachers.
“We’re finding that from talking to teachers as well that they are really struggling to work out how to broach these topics with the students that they are working with and how to make that a really safe space and open space to have those conversations in an age-appropriate way, which can be very challenging.”

Hidden domestic abuse deaths
Charities like Tender exist to prevent domestic abuse and sexual violence.
Ms Lexen says without tackling misogynistic behaviours “early on with effective prevention education” then the repercussions, as the data for under 25s proves, will be “astronomical”.
At Refuge, it is already evident. Elaha Walizadeh, senior programme manager for children and young people, says the charity has seen a rise in referrals since last year.

“We have also seen the dynamics of abuse changing,” she adds. “So with psychological abuse being reported, we’ve seen a rise in that and non-fatal strangulation cases, we’ve seen a rise in as well.
“Our frontline workers are telling us that the young people are telling them usually abuse starts from smaller signs. So things like coercive control, where the perpetrators are stopping them from seeing friends and family. It then builds.”
Misogyny to violent behaviour might seem like a leap.
But experts and survivors are testament to the fact that it is happening.
