British teenager program to kill family members is sentenced to 49 years in prison – National
A British teenager has been sentenced to at least 49 years in prison for murdering three immediate family members and planning a mass murder case in a primary school.
Nicholas fatally shot his mother, Juliana Falcon, 48, his brother Kyle and his 13-year-old sister Giselle, in their apartment in Luton, England, on September 13, 2024.
Shortly after the murder, the 19-year-old was arrested by police on the street when he signaled to police on his way to his former primary school that he planned to continue the rampage.
Prosper arrested police body camera footage shows his hands still stained with blood from his family. He could also hear him repeating, “This is not a murder.”
During a sentence at Luton Crown Court on Wednesday, Judge Chema Grub said: “These beliefs are shocking facts,” the killer said: “Your ambition is notorious and you want to be known as the world’s most famous 21st century school shooter after death.”
She continued: “The lives of your own mother and brother and sister will be collaterally damaged on the way to fulfill your ambitions.”
After failing to pass the A-level (a senior, subject-based exam taken by British students aged 16 to 18), Prosper plans murders for about a year, where certain grades are required to obtain college admission).
He had planned to kill 34 people, including his family, under four years old, two teachers and himself.
The judge said he wanted to murder more than the recent deadliest school shooting in recent history held at Virginia Tech in 2007.
In the year of the murders, Prosper's internet history shows the mass shootings and his old elementary school. He also saved images of employees and students from the website and used a wooden board to imitate murder weapons to create a home video of himself rehearsing his murder plan in his bedroom.

In the video, he promises to “dismember” his sister's face “more than necessary.”
According to the Telegraph, Prosper is a “social hermit” who grew up to idolize Adam Lanza, the perpetrator of the mass shooting at Sandy Hook Elementary School, and claimed 26 lives, including 20 children aged six to seven, and six adult employees.
Before entering school, Lanza murdered his mother at home, eventually taking her own life.
During the sentencing period, Cheema-Grubb described a chart – a chart drawn by Prosper after being arrested – in a classroom in an elementary school where he aimed at the word “kill” written next to him.
In August 2024, Prosper obtained a fraudulent gun certificate that he used to buy shotguns and will use 100 cartridges with private weapons sellers next month.
Video shows him meeting the seller in a parking lot in Luton. A moment later, the security camera captured the prosperity and returned to his apartment with a gun hidden in the bag. The next morning, he killed his family.
Shortly after the murder, a neighbor named 999 told police she knocked on the door of a family unit after hearing “a huge explosion that sounded like gunshots.”
