A 19-year-old man who murdered his mother and two younger siblings as part of a failed plot to kill 30 children at his former primary school has been sentenced to life imprisonment with a minimum term of 49 years. Nicholas Prosper admitted killing Juliana Falcon, 48, Kyle Prosper, 16, and Giselle Prosper, 13, at their home in Luton in September.
The court heard that Prosper planned to storm a morning assembly at St Joseph's Catholic Primary School, where he and his siblings had been pupils, intending to become the worst mass murderer in British history. He had surveilled the school, taken images of staff and students, and noted lesson times. He bought a shotgun for £650 using a forged certificate.
His plan was thwarted when his mother confronted him after realising he had a gun. A violent struggle ensued, resulting in the deaths of all three family members. Juliana was shot in the head and had defensive knife wounds; Giselle was shot in the face and found hiding under a table; Kyle was shot twice and had over 100 knife wounds.
Neighbours alerted police after hearing shouts and gunshots. Prosper fled but later flagged down officers, believing his plan had failed. He was arrested carrying the shotgun and 33 cartridges intended for the school attack. The judge, Mrs Justice Cheema-Grubb, described him as 'truly evil' and said his ambition was notoriety.
The father, Raymond Prosper, said the deaths of his family likely saved the lives of many children, and he praised their memory. Detective Chief Inspector Sam Khanna said he had never encountered anyone capable of such horrific acts in his career.
