Man pleads guilty to murdering three members of his own family

A man from Luton has pleaded guilty to murdering three members of his own family. 

Nicholas Prosper, 19, of Leabank Court, Luton, appeared at Luton Crown Court today (Monday) where he pleaded guilty to three counts of murder.

Juliana Falcon, 48, Kyle Prosper, 16, and Giselle Prosper, 13, were shot dead by Prosper at their home address in the early hours of Friday 13 September 2024.

They were found when a concerned neighbour called police after hearing a disturbance at around 5.30am.

Prosper was arrested by officers shortly afterwards in Bramingham Road and a loaded shotgun was found hidden in bushes nearby, along with more than 30 cartridges.

Following the triple murder, an investigation was launched by officers from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit.

During the course of the investigation, officers discovered how Prosper had also planned to commit a shooting at a local school but was apprehended by officers before he could carry out his plans.

Detective Chief Inspector Sam Khanna, from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit, said: “This was a truly tragic and shocking case in which three innocent members of the same family have been brutally killed by their son and brother.

“No words can fully describe the tragedy their loved ones have experienced, and our thoughts continue to be with them at this difficult time. We are pleased that Prosper has pleaded guilty and will not put his family through the pain of a trial, and that he will soon face a significant jail sentence.

“What was subsequently uncovered during our investigation left no doubt as to his intentions to carry out an attack at a school, but fortunately Prosper was apprehended before he could cause any further harm.”

Assistant Chief Constable John Murphy said: “We understand the deep shock this case will have on people within Luton and across the country.

“Juliana, Kyle and Giselle were brutally murdered in their home by someone intent on causing the maximum harm and distress on not only his family, but to the wider community.

“We are extremely grateful to our officers who stopped him and prevented him from going through with his plans to target a school.

“We are working closely alongside Luton Borough Council to engage with schools in Luton to provide support, assistance and guidance to both schools and parents.”

Police and Crime Commissioner John Tizard said: My thoughts are with Juliana, Kyle and Giselle, their family and friends at what must be an incredibly difficult time.

“There can be no excuse for such a horrific, premeditated act. I would like to extend my extreme gratitude for the attending officers for swiftly arresting the offender. Their action prevented further devastation to our communities.

“Thank you too, to all of the police officers and police staff, and the CPS who have worked so diligently to bring the offender to justice.

Councillor Hazel Simmons MBE, Leader of Luton Council, said: “First and foremost, we must remember the three innocent victims of these senseless murders. Our thoughts and prayers are very much with them today, along with their family, friends and the wider community who are still deeply impacted by what happened last year.

“The revelation that the perpetrator had plans to cause further harm in one of our schools is extremely shocking, distressing and upsetting; and we don’t underestimate the emotional difficulty this news will have on children, staff, parents and carers across our school community.

“Our schools have robust systems in place to keep children safe and security is constantly reviewed and monitored. Just recently we asked our schools to further review security and for increased vigilance following the incident in a school in Sheffield. We will be asking schools to further review security measures in light of what came out in court today.

“On behalf of the town I would like to thank and praise the excellent work of Bedfordshire Police for apprehending the perpetrator before he attempted to cause more harm. However, we know this case will be unsettling for parents which is why the council is working with schools to put support in place in our schools to anyone who needs it.”

Prosper appeared at Luton Crown Court on Monday (24 February) where he pleaded guilty to:

• three counts of murder
• possession of a knife blade in a public place
• purchasing or acquiring a shotgun without a certificate
• possession of a shotgun with intent to endanger life

He has been remanded in custody ahead of sentencing at Luton Crown Court on 5 March.
