Nicholas Prosper, 19, has been sentenced to life in prison with a minimum term of 49 years for the murders of his mother and two siblings in Luton. Prosper pleaded guilty to killing Juliana Falcon, 48, Kyle Prosper, 16, and Giselle Prosper, 13, whose bodies were found in their home in September last year.

During sentencing at Luton Crown Court, the judge described the murders as “chilling” and said the words “heartless and brutal” were inadequate to capture the suffering of the victims.
Prosper had been planning a mass shooting at his former primary school, St Joseph’s Catholic Primary School, with the intention of becoming “the world’s most famous school shooter of the 21st century,” according to police. Authorities believe he murdered his family after his mother discovered a shotgun he had illegally obtained with a fake certificate and confronted him.
His plot was foiled when officers spotted him in the street shortly after the killings and arrested him. A loaded shotgun and more than 30 cartridges were later recovered from nearby bushes.
During the trial, prosecutors described Prosper’s actions as “cold, deliberate, and without sympathy or emotion.” The judge, Mrs. Justice Cheema-Grubb, noted that he had drawn inspiration from previous U.S. school massacres, including those at Sandy Hook in 2012 and Virginia Tech in 2007.

Prosper admitted to a prison nurse that he wished he had killed more people and showed no remorse. When asked by a psychiatrist whether he would attempt another massacre if released, he reportedly responded, “Well, that’s their job to stop me getting the weapons.”
While the court acknowledged that Prosper had autism spectrum disorder, the judge determined it was not the primary factor behind his crimes.
A statement from the victims’ family, read outside the court, emphasized that their deaths had prevented further tragedy. “For now, we would ask people to remember Juliana, Kyle, and Giselle for the people they were,” the statement said, describing them as loving, kind, and full of potential.
