A life sentence with a minimum term of 49 years has been handed down to 19-year-old Nicholas Prosper, who murdered his mother and two siblings while planning a mass attack at a school.
Cold Calculation and a Goal of “Fame”
On September 13, 2023, Prosper killed his mother, Juliana Falcon (48), his sister, Giselle Prosper (13), and his brother, Kyle Prosper (16) in their apartment in Luton.

According to the investigation, he aimed to surpass the Sandy Hook (2012) and Virginia Tech (2007) school massacres, aspiring to become “the most infamous school shooter of the 21st century.”
His plan was to carry out a mass attack at St. Joseph’s Catholic Primary School, where he had once studied. Authorities believe he murdered his family after his mother discovered a gun he had obtained using a forged license and confronted him.
However, his killing spree was cut short when police arrested him shortly after the murders. His loaded firearm was found hidden in nearby bushes, along with over 30 rounds of ammunition.
No Remorse – “I Wish I Had Killed More”
During the trial, prosecutors described Prosper as cold and remorseless.
Judge Bobbie Cheema-Grubb told him, “Your primary goal was fame. You wanted to be remembered posthumously as the greatest school shooter of the 21st century.”
It was also revealed that he had planned to kill his family in their sleep and assault his sister. According to case records, when speaking to a prison nurse, Prosper expressed regret only for not killing more people.
When asked by a psychiatrist if he would attempt another massacre if released, he responded: “That’s their job to prevent it.”
Autism Diagnosis but Not a Key Factor
The defense argued that Prosper had been diagnosed with Autism Spectrum Disorder.
However, the judge ruled that his condition did not significantly impact his decision-making and that his actions were coldly calculated.
Heartbreaking Statement from the Victims’ Family
Outside the court, the victims’ relatives released a statement emphasizing that their family’s sacrifice had saved other lives.
“Now we understand that the loss of Juliana, Kyle, and Giselle had a greater meaning because it prevented another tragedy,” they said.

They also urged people to remember their loved ones for who they truly were:
- “Juliana was a strong, loving mother to her four children.”
- “Kyle was a kind and funny young man, talented in football and boxing.”
- “Giselle was a sweet soul, a top student, with a smile that lit up everything around her.”
