A teenager who was planning a mass shooting at his old primary school has been jailed for life with a minimum term of 49 years for murdering his family.
Nicholas Prosper, from Luton, pleaded guilty to the murder of his mother, Juliana Falcon, 48, and his siblings, Kyle Prosper, 16, and 13-year-old Giselle Prosper at Luton Crown Court in February.
Their bodies were found at their flat in the town in September last year.
The 19-year-old planned to carry out a mass shooting at St Joseph’s Catholic Primary School, where Prosper and his siblings had been pupils, he admitted to police.
Police believe he killed his family when his mother found a shotgun he had bought using a fake certificate and confronted him.
His scheme was eventually foiled by officers who spotted him in the street immediately after the murders and arrested him.

The loaded shotgun was found hidden in bushes nearby, along with more than 30 cartridges.
As his sentencing started on Tuesday, the court heard that “his planning was cold, deliberate and without sympathy or emotion towards the actual victims or potential victims”.
Judge Mrs Justice Cheema-Grubbfacts said the details of Prosper’s case were “chilling”, and that he had wanted to emulate and outdo the US school massacres at Sandy Hook in 2012 and Virginia Tech in 2007.
His “main wish”, according to the prosecution, was notoriety, telling a prison nurse “I wish I had killed more”, and he wanted to cause “the biggest massacre in the 21st century”.
