A teenager who murdered his family and wanted to be the worst mass killer the UK has seen had 33 cartridges on him to carry out an attack on his former school, a court has heard.
Nicholas Prosper shot his mother Juliana Falcon, 48, sister Giselle, 13, and shot and stabbed his brother Kyle, 16, at their family home in Luton on 13 September last year.
But the 19-year-old did not plan on stopping there, according to prosecutor Timothy Cray KC, who told Luton Crown Court he had prepared the murders “for months” and wanted to kill at least 30 schoolchildren.
“His planning was cold, deliberate and without sympathy or emotion towards the actual victims or potential victims,” Mr Cray said, speaking at Prosper’s sentencing.
His “main wish”, however, was to “achieve lasting notoriety as a mass killer”, Mr Cray added, specifically to “imitate and even surpass other mass killers around the world”.
“He had conducted in-depth internet research on shootings in the United States of America, Norway, Australia and New Zealand,” he said.
“He understood his plans, if realised, would bring about the greatest number of deaths in a school or other mass shooting in the United Kingdom and possibly even in the United States of America.”

The investigation suggests that the defendant “acted alone”, he added, and “his plans did not arise from any political or ideological cause”.
Prosper had undiagnosed autism spectrum disorder (ASD), the court heard, but he showed an “extreme lack of empathy with others and an extreme lack of remorse” that can’t be explained by ASD alone.
Up until Year 11, the court heard Prosper was a “geeky” and quiet boy with a small group of friends who were into computers, but problems began in sixth form and he wouldn’t engage with mental health support.
‘Extended violent struggle’
Prosper never reached St Joseph’s Catholic Primary School, which was three-quarters of a mile from his home, as police arrested him after he escaped to a wooded area.
After he left, officers broke into his family flat at about 5.50am, following a call from a neighbour.
There, the court heard, they found Prosper’s little sister underneath a dining table in the living room, “as if she had been trying to hide there”.
His mother and brother – who was stabbed more than 100 times – were both found in the hallway.

He had planned to kill his family in their sleep, but when his mother realised something was wrong and challenged him, it led to “an extended violent struggle”.
After the horrific and noisy attack on his family members, Prosper knew police would be on their way and so had to leave three hours earlier than he had anticipated.
The teenager was then arrested by a passing police patrol as he walked along a residential road in Luton.
He had hidden the shotgun and cartridges nearby.
Prosper admitted their murders at a hearing last month, as well as purchasing a shotgun without a certificate, possession of a shotgun with intent to endanger life and possession of a kitchen knife in a public place.
Plans long in the making
These killings were planned for more than a year, the court heard, with Prosper managing to buy a shotgun with a fake firearms certificate.
He had put together a black and yellow uniform he wanted to wear for his killing spree, and he had filmed a video of himself holding a plank of wood as a mock gun.

Prosper had included his own name, a picture and his real address on his fake firearms licence, the court heard.
He had also inserted the signature of a Bedfordshire Police firearms sergeant on 30 August last year.
On the same day, Prosper messaged a private seller who had advertised a shotgun for £450, offering to pay £600 if cartridges were included, Mr Cray said.
The seller agreed to drop the gun off to him on 12 September, the day before the killings, prompting Prosper to respond in a message: “I look forward to meeting you.”
Forensic examiners found Prosper had fired seven cartridges, the first being a test shot into a teddy bear in his bedroom.
Prosper’s step-by-step plan
A couple of months later, a prison officer found the notes in Prosper’s trainer sole after searching his cell on 13 November.
He had written the planned shooting would be “one of the biggest events ever,” Mr Cray said.

“I was right in predicting no-one would’ve called the police had I killed them in their sleep. 3 shots under 30 seconds,” he had written.
“The only known phone call to police that day was made by the b**** at the door as a result of my B**** mother waking them up and it being turned into a long struggle.
“My plan wasn’t ‘stupid’. I was f****** right. MY MOTHER IS A STUPID F****** COW.”
The notes continued: “But why so early? So I’d have time to cannibalise my family, and rape a woman at knife point before the shooting.”
He had also written a step-by-step plan, detailing he would jump two gates and shoot down a glass door while children were together for “prayer/registration”.
He would then “shout that this is a robbery and for everyone to get down”, before shooting two teachers and killing children at Early Years Foundation Stage – the youngest.
That part of the note finished with: “Go to the next classroom. Kill a couple more. Suicide.”
‘Pain will never heal’
His father, who was also dad to Giselle and Kyle, said part of his soul died when he found out what his son had done.
In a statement read out by Mr Cray, Raymond Prosper said: “The pain of our loss will never be healed. This includes my whole family, our lives will never be the same.
“When I heard the horrific news on that day, part of my soul died too. This is a lose-lose situation for us all.”
Sir Keir Starmer has joined other European leaders in Kyiv to press Russia to agree an unconditional 30-day ceasefire.
The prime minister is attending the summit alongside French President Emmanuel Macron, recently-elected German Chancellor Friedrich Merz and Polish Prime Minister Donald Tusk.
It is the first time the leaders of the four countries have travelled to Ukraine at the same time – arriving in the capital by train – with their meeting hosted by President Volodymyr Zelenskyy.

It comes after Donald Trump called for “ideally” a 30-day ceasefire between Kyiv and Moscow, and warned that if any pause in the fighting is not respected “the US and its partners will impose further sanctions”.
Security and defence analyst Michael Clarke told Sky News presenter Samantha Washington the European leaders are “rowing in behind” the US president, who referred to his “European allies” for the first time in this context in a post on his Truth Social platform.
“So this meeting is all about heaping pressure on the Russians to go along with the American proposal,” he said.
“It’s the closest the Europeans and the US have been for about three months on this issue.”

Ukraine’s foreign minister Andrii Sybiha said Ukraine and its allies are ready for a “full, unconditional ceasefire” for at least 30 days starting on Monday.
Ahead of the meeting on Saturday, Sir Keir, Mr Macron, Mr Tusk and Mr Merz released a joint statement.
European leaders show solidarity – but await Trump’s backing
The hope is Russia’s unilateral ceasefire, such as it’s worth, can be extended for a month to give peace a chance.
But ahead of the meeting, Ukrainian sources told Sky News they are still waiting for President Donald Trump to put his full weight behind the idea.
The US leader has said a 30-day ceasefire would be ideal, but has shown no willingness yet for putting pressure on Russian president Vladimir Putin to agree.
The Russians say a ceasefire can only come after a peace deal can be reached.
European allies are still putting their hopes in a negotiated end to the war despite Moscow’s intransigence and President Trump’s apparent one-sided approach favouring Russia.
Ukrainians would prefer to be given enough economic and military support to secure victory.
But in over three years, despite its massive economic superiority to Russia and its access to more advanced military technology, Europe has not found the political will to give Kyiv the means to win.
Until they do, Vladimir Putin may decide it is still worth pursuing this war despite its massive cost in men and materiel on both sides.
“We reiterate our backing for President Trump’s calls for a peace deal and call on Russia to stop obstructing efforts to secure an enduring peace,” they said.
“Alongside the US, we call on Russia to agree a full and unconditional 30-day ceasefire to create the space for talks on a just and lasting peace.”

The leaders said they were “ready to support peace talks as soon as possible”.
But they warned that they would continue to “ratchet up pressure on Russia’s war machine” until Moscow agrees to a lasting ceasefire.
“We are clear the bloodshed must end, Russia must stop its illegal invasion, and Ukraine must be able to prosper as a safe, secure and sovereign nation within its internationally recognised borders for generations to come,” their statement added.
“We will continue to increase our support for Ukraine.”

The European leaders are set to visit the Maidan, a central square in Ukraine’s capital where flags represent those who died in the war.
They are also expected to host a virtual meeting for other leaders in the “coalition of the willing” to update them on progress towards a peacekeeping force.
Military officers from around 30 countries have been involved in drawing up plans for a coalition, which would provide a peacekeeping force in the event of a ceasefire being agreed between Russia and Ukraine.

A special constable has been jailed after taking pictures on his phone from bodycam footage showing a dying man.
Former police volunteer William Heggs, 23, was sentenced to 12 months’ imprisonment at Leicester Crown Court on Friday after showing the photos of victim William Harty, 28, to a female colleague and storing them on his Snapchat account.
Mr Harty was found seriously injured in a residential street in Leicester on 25 October 2021 and Heggs had attended the scene, helping with CPR before paramedics arrived.
Mr Harty died in hospital a day later and the man responsible for his injuries, his brother-in-law Martin Casey, was subsequently convicted of his manslaughter.
Heggs showed the pictures he had taken of bodycam footage of Mr Harty’s body to a Leicestershire Police constable, who reported Heggs and said she did not like seeing blood.
His phone was seized and officers discovered other photographs and video clips of bodyworn footage of incidents Heggs had attended on duty, including of a knife seizure, use of baton and pepper spray, and a man with an injured hand receiving first aid.
He also took pictures of a police computer screen, showing details of crimes and suspects, without consent.

Heggs stored the materials in a Snapchat folder and disclosed graphic details – most of which were not in the public domain – about the injuries to a woman who was killed in a road traffic collision he had attended, to a friend on the social media platform.
Heggs was suspended from the force in November 2021 and resigned in October 2024 before pleading guilty to 11 computer misuse and data protection offences this March.

‘He has traumatised me’
Mr Harty’s widow, Mandy Casey, said in a victim impact statement read to the court that Heggs “took (her) husband’s dignity when he was most vulnerable”.
“You don’t take someone’s dignity and pride from them on their deathbed.”
She continued: “When I found out special constable Heggs had done this, I just wanted to ask why. He has traumatised me. I feel I will never know if he showed them to others.”
Ms Casey said she was still scared that photos of her husband’s body might appear on social media.
She added that she had lost trust in the police.
Public trust in police ‘significantly undermined’
Judge Timothy Spencer told Heggs, who has autism and ADHD, that he was “probably too immature to be working as a police officer” as he handed down the sentence.
He said Heggs had received “extensive training”, including on the importance of data protection, and knew he should only share materials for “a genuine policing purpose”.
Heggs’s actions had “significantly undermined” public trust and confidence in police, according to the judge.
Malcolm McHaffie, from the Crown Prosecution Service, added: “William Heggs abused the public’s trust in the office he held as a special police constable.
“He violated the dignity of the deceased victims for no apparent reason other than what could be considered personal fascination and to gain credibility among his peers.”
