Triple killer who wanted to be notorious mass murderer jailed for life

A triple murderer who killed three members of his family and was plotting a school shooting has been jailed for life with a minimum term of 49 years.

Nicholas Prosper, 19, from Luton, who wanted to become a notorious mass murderer, was sentenced at Luton Crown Court on Wednesday.

He was jailed for life for the murders with a minimum term of 49 years – a total of 48 years and 177 days when the amount of time he has already been in custody is taken into account.

Mrs Justice Cheema-Grubb told him: “You intended to unleash disaster on the community of Luton. Your plans were intelligent, calculating and selfish.

“Your ambition was notoriety. You wanted to be known posthumously as the world’s most famous school shooter of the 21st century.

“The lives of your own mother and younger brother and sister were to be collateral damage on the way to fulfil your ambition.”

He had to be ordered to come to court after initially refusing to attend the second day of his sentencing hearing.

Prosper shot his mother Juliana Falcon, 48, and siblings Giselle Prosper, 13, and Kyle Prosper, 16, at the flat the family shared in Luton, Bedfordshire, on September 13 last year, and stabbed his brother more than 100 times.

He hid for just over two hours before flagging down police officers in a nearby street and showing them where he had hidden a loaded shotgun and 33 cartridges near playing fields.

The teenager, who had been unable to stay in education or hold down a job, had been planning to carry out a mass shooting at his old primary school driven by a desire for notoriety.

A forensic psychiatrist said he had “an extreme lack of empathy and remorse”, which were psychopathic tendencies.

Prosper managed to forge a gun licence and used it to buy a shotgun and 100 cartridges from a legitimate firearms dealer the day before the murders.
