LONDON — A 19-year-old British man who brutally murdered his mother and two younger siblings, with aspirations of carrying out a large-scale school shooting, has been sentenced to a minimum of 49 years in prison before becoming eligible for parole.
During Wednesday’s sentencing at Luton Crown Court, Justice Bobbie Cheema-Grubb acknowledged the severity of Nicholas Prosper’s crimes. While she considered imposing a full life sentence, she ultimately decided against it due to his age—he was 18 at the time of the killings—and his guilty plea.
Last month, Prosper admitted to murdering his 48-year-old mother, Juliana Falcon, along with his 13-year-old sister, Giselle, and 16-year-old brother, Kyle, in their Luton apartment on September 13. He had also stabbed his brother more than 100 times.
The court heard that Prosper was obsessed with infamous mass shootings and sought to surpass them in scale. His inspirations included the 2012 Sandy Hook Elementary School massacre in Connecticut, where 26 people—mostly children—were killed, and the 2007 Virginia Tech shooting, which left 30 dead.
“You craved notoriety,” Justice Cheema-Grubb told Prosper, who had to be forcibly brought into court for the hearing. “Your goal was to be remembered as the most infamous school shooter of the 21st century.”
She highlighted several disturbing patterns in Prosper’s case, commonly seen in mass shootings worldwide, including his withdrawal from society, lack of empathy, sexual interest in children, and the deliberate choice of an outfit for his attack.
Unable to hold a job or stay in school, Prosper had successfully forged a gun license, allowing him to legally purchase a shotgun and 100 rounds of ammunition from a firearms dealer just a day before the killings. His ultimate plan was to commit a mass shooting at his former elementary school on Friday the 13th.
At around 5 a.m. on the morning of the murders, he test-fired the weapon into a teddy bear in his bedroom. His mother, sensing something was terribly wrong, was the first to wake. Prosper shot her, placing a copy of the novel How to Kill Your Family on her legs. He then turned his gun on his younger sister, who had been hiding under a table, before stabbing and shooting his brother.
“Their lives—your own mother, brother, and sister—were nothing more than collateral damage on your path to achieving infamy,” the judge declared.
Following the killings, Prosper flagged down police officers nearby and directed them to where he had hidden a loaded shotgun and 33 remaining cartridges.
Detective Superintendent Rob Hall of Bedfordshire Police read a statement from Prosper’s father, Raymond, who expressed deep grief over the loss of his former partner and children.
“Their deaths, along with the swift response of Bedfordshire Police, prevented another family in this community from experiencing the same unimaginable pain we have endured,” he said.
