A Channel 4 documentary will examine the murders of Juliana Falcon, Giselle Prosper and Kyle Prosper and a foiled Luton school shooting plan, described by Bedfordshire Police as “one of the most shocking incidents in our force history”.
The two-part series, made by the team behind 24 Hours in Police Custody, will air at 9pm on Sunday 5 and Monday 6 October. It follows the investigation known as Operation Longacre, which began after the triple familial killing in Marsh Farm on September 13, 2024, and uncovered plans to target a Luton school.
Bedfordshire Police Deputy Chief Constable Dan Vajzovic said he allowed cameras inside the investigation only after careful thought, emphasising the force’s aim to keep focus on the victims, not their killer, Nicholas Prosper, who was given a 49-year minimum term in jail in May, though the Court of Appeal rejected a request in July for the 19-year-old to never be released from prison.
“Throughout this case I have been determined not to provide the perpetrator with the notoriety that he craved,” he said, adding: “The decision to allow Garden Productions to follow the case was therefore not one that I took lightly.”
DCC Vajzovic said the film can “shine a spotlight on some of the issues raised by this case”, including weaknesses in the firearms licensing system. He added he has been working with national partners to help close loopholes and hopes the programme “helps to bring about real change”.
The deputy chief also pointed to the risk of young men being radicalised online without a specific ideology.
“The on-going 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 again I hope this documentary continues to contribute to the debate around legislative change in this area,” he said.
Highlighting the impact television can have in sparking conversations, DCC Vajzovic drew a parallel with another hit television show, saying: “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.”
He praised the “bravery, professionalism and compassion” of officers and staff who handled the traumatic case and urged anyone affected to use the force’s wellbeing services.
