Nicholas Prosper: Teen who murdered family 'planned on killing at least 30 schoolchildren'

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."

Sentence will be passed on Wednesday.
