Documentary to spark gun debate after Prosper case

Nicholas Prosper wanted to be remembered by the distinctive black and yellow outfit he wore during the school attack

A TV documentary that follows the work of a police force will show how the investigation into the actions of a teenage killer unfolded.

Nicholas Prosper used a shotgun to kill his mother Juliana Falcon, 48, his brother Kyle, 16, and his 13-year-old sister, Giselle, at their home in Luton on 13 September 2024.

The 19-year-old, who was arrested in the hours after the murders, was jailed for 49 years in March. A trial heard he intended to carry out a shooting at his former primary school.

The Channel Four series 24 Hours in Police Custody, which follows the work of investigators at Bedfordshire Police, will feature the case over two nights on 5 and 6 October.

Juliana Falcon, her son Kyle Prosper and daughter Giselle were found dead at their home in Luton in September 2024

Prosper was apprehended by police before he could carry out the shooting at St Joseph's Catholic Primary School, where he wanted to kill children and teachers, before killing himself.

The trial heard he had a fascination with mass shooters, idolising the perpetrator of the 2012 Sandy Hook killings in the United States, and his internet history included him watching extremely violent content.

Deputy Chief Constable Dan Vajzovic said: "We have seen recently, with programmes such as Adolescence, the power that TV can have in terms of opening up important conversations between parents, carers, young people and society as a whole in relation to the issues our children are facing today.

"The ongoing debate around the dangers of explicit material online and the propensity for young men in particular to be radicalised into carrying out violence without any specific ideology continues, and I hope this show continues to spark debate and legislation change around these issues."

Luton Crown Court heard Prosper had deceived a private gun seller online using a forged shotgun licence to acquire the weapon.

Bedfordshire's Labour police and crime commissioner John Tizard said the case exposed weaknesses in the current law.

Mr Vajzovic added: "It is also very important to me that we highlight the issues within the firearms licensing system to help close any loopholes and prevent this from happening again.

"It's something that I've been liaising with partners at a national level about already, and I hope the programme helps to bring about real change in this area.

"Throughout the programme, you will see first-hand the bravery, professionalism and most of all the compassion that our officers showed throughout this complex investigation, with the victims remaining at the forefront for everyone involved at every step of the investigation."
