Sadistic teen who shot dead family ‘wanted to be worst mass school killer in UK’ and planned to murder 30 young children
A SADISTIC teen who shot his family dead wanted to be the worst mass school killer in the UK and plotted to murder 30 children.
Nicholas Prosper, 18, killed Juliana Prosper, 48, Kyle Prosper, 16, and Giselle Prosper, 13, in cold blood at home in Luton in September.
After slaughtering his family, the warped teen was stopped by police near his home after plotting a “cold, deliberate and without sympathy” massacre at his old primary school.
Officers discovered a loaded shotgun discovered in bushes nearby alongside more than 30 cartridges – one for each child Prosper planned to kill.
He had chillingly written “kill all” on a diagram that showed the early years classroom at St Joseph’s.
Prosper is currently being sentenced after he pleaded guilty to murdering his mum and two siblings.
He also admitted a number of other offences – including possession of a shotgun with intent to endanger life, possession of a bladed article in a public place and purchasing or acquiring a shotgun without a certificate.
It can now be revealed that Prosper had a sick desire to carry out Britain’s worst mass shooting by opening fire at a primary school.
The teen wanted to achieve “lasting notoriety” and wanted to “imitate and even surpass” other mass killers around the world.
Prosecutor Timothy Cray KC 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.”
Prosper had written a chilling note that told how this would be “one of the biggest events ever”.
The court was told he was “not just play acting or fantasising” and that “what drove him on most was the desire to be famous or infamous as a mass killer”.
He managed to get his hands on the deadly weapon by creating a fake firearms licence.
Prosecutors believe he plotted to slaughter kids as young as four then take his own life.
But the murder of his family was “killing for the sake of killing”, Luton Crown Court heard.
The horror unfolded on September 13 at the family’s flat on Wauluds Bank Drive.
Police had swarmed the home at around 5.30am after neighbours heard “loud bangs” that sounded like shots being fired and “groaning” coming from inside.
Officers discovered Juliana and two of her four children dead inside the flat, having all been shot in the head.
Kyle had also been stabbed more than 100 times, while Giselle was found under a table as though she had been “trying to hide”.
He fired seven shots in total – the first being a test shot on a teddy bear in his bedroom – meaning he would have stopped to reload twice.
Officers found blood splattered throughout the flat, with Kyle shot and stabbed in the kitchen.
His sister was discovered in the living room of the property and mum Juliana was in the hallway.
The court heard Prosper originally planned to kill his family in their sleep then remain in the flat with their bodies until the primary school had filled up with children.
But his murderous plan was interrupted when his loved ones “realised something was terribly wrong and challenged him”.
This led to an “extended, violent struggle”, the prosecutor said.
Prosper's chilling internet searches
THE court was told Prosper was “continuously” on his phone between midnight and 4am on the morning of the triple murder.
He searched for “shotgun injuries to the neck” as well as other sadistic terms.
These included:
- What will happen on 13th September?
- Do you die if shot in the neck?
- Does sex with a corpse feel good
- Man shoots woman in the head at close range
- Woman raped and killed
- How lethal are neck gunshots
Prosper also searched for the murder of Sarah Everard.
After the horror, it emerged loner Prosper had a chilling internet history and had plotted the attack for over a year.
He had shared a number of vile videos leading up to the killings on social media where he defended paedophiles and necrophilia.
Prosper also poured over previous school shootings – including the 1999 Columbine High School massacre.
At the time, he was showing a “deep alienation from normal life and interest in the darkest sides of humanity”.
The court heard Prosper had undiagnosed autism spectrum disorder (ASD), but displayed “extreme lack of empathy with others and an extreme lack of remorse” that cannot be explained by ASD alone.
He emailed a woman whose child had been murdered, asking to see pictures of them.
Prosper also accessed one site that showed videos of people’s final moments before they died but was banned after making pro-paedo comments.
He hatched the barbaric plan by researching how to fake a firearms certificate around a year before the horror.
This plot was put into practice on September 12 – the day before the fatal shooting – when he picked up the shotgun in a car park.
The seller had been “deceived” by his “high quality forgery” of a shotgun licence”, the court heard.
Prosper had messaged him on a gun website after seeing the weapon on sale for £450 and offered to pay him £600 if cartridges were included.
Footage showed the teen approaching the seller and shaking hands before taking hold of the weapon.
It is believed he was forced to move his plans forward when his mum got suspicious.
The warped teen also had an obsession with a child character called Clementine from The Walking Dead video game.
In one clip posted after the killings, he told the camera: “I am the chosen one; chosen by Clementine. I am guided as Christians are guided by Jesus Christ.”
He also threatened sister Giselle over her “incorrect choice” on the game.
Prosper said: “On June 30, my sister decided to make the incorrect choices on episode one of season one of The Walking Dead games, and for that her face will be mutilated further than necessary.”
Hours later, the monster fatally shot Giselle in the head along with his mum and brother.
Prosper had then planned to head to St Joseph’s Catholic Primary School in Luton and carry out the mass shooting.
The plot was foiled by police, who had seen him acting suspiciously after shooting dead his family.
Paying tribute to Kyle, Giselle and Juliana, their devastated family said: “Julie was a strong, loving mother to her four beautiful children, who were her absolute world.
“In her spare time, she was a keen athlete and enjoyed raising money for charity – she was always putting others first.
“Kyle was a kind and funny young man who loved football and boxing.
“He was creative and thriving on TikTok, a big talent with massive potential.
“Kyle’s friends were his everything.
“Giselle was a beautiful soul and caring young girl; she liked to laugh lots and loved her family and big brothers.
“She was so loveable with an infectious smile.
“She was also an exceptional pupil at school and was loved dearly by her friends in Year 9.”
