Man who killed family also planned school shooting

Juliana Falcon, 48, Kyle Prosper, 16, and Giselle Prosper, 13, were found dead at their home
A man who killed his mother and two siblings was also planning to commit a mass shooting at his former primary school, police have confirmed.
Nicholas Prosper shot dead Juliana Falcon, 48, Kyle Prosper, 16, and 13-year-old Giselle Prosper at their home in Luton in September.
The 19-year-old intended to carry out an attack at the school and a loaded shotgun with more than 30 cartridges was found in a bush after his arrest, police said.
He pleaded guilty to three counts of murder at Luton Crown Court on Monday.
Det Ch Insp Sam Khanna, from Bedfordshire Police, said "fortunately Prosper was apprehended before he could cause any further harm".
"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," said Det Ch Insp Khanna.
"What was subsequently uncovered during our investigation left no doubt as to his intentions to carry out an attack at a school."
Speaking outside court, he added that his team was in "shock and disbelief" when they learned of his plans to target St Joseph's Catholic Primary School in Luton.

Assistant Chief Constable John Murphy said Prosper planned to cause maximum harm to the "wider community".
"We are extremely grateful to our officers who stopped him and prevented him from going through with his plans."
Mr Murphy said police were working with the council to give support, assistance and guidance to schools and parents.
At a press conference he added that "comprehensive inquiries demonstrate that this was a single perpetrator acting in isolation".
Maureen Murphy, the head teacher at St Joseph's, said in a statement that all the children from the family had attended the school and had been a "cherished part" of its community.
She said parents could be reassured there was no threat to the school and that "robust" safety systems were in place.
"We are proud to be a multicultural Catholic school where the safety of children will always be our number one priority and this will never be compromised," said Ms Murphy.
The leader of Luton Council, Hazel Simmons MBE, said the council had recently asked schools to conduct a security review following the fatal knife attack in Sheffield - but said all of them would be asked to conduct a further review.

Officers were called to the family flat in Leabank, off Wauluds Bank Drive, at about 05:30 BST after a concerned neighbour said they heard a disturbance.
An inquest at Bedford Coroner's Court in October was told that all three of the victims died from gunshot wounds to the head.
Speaking previously Det Supt Rob Hall, from the region's major crime unit, said officers who arrived at the scene were "met with such awful circumstances".
Prosper was arrested shortly after and the firearm was found in the bushes during a search of the surrounding area.
Shortly after the murders, Kyle's most recent school in Luton said it was "deeply saddened" by his death.
"This is devastating news to all those who knew and loved Kyle and it will take some time to come to terms with the profound sense of loss," the school said.
The head teacher at Giselle's secondary school said in a statement: "Giselle was a beautiful soul and a model pupil.
"She excelled in all her subjects and will be sorely missed, particularly by her friends in Year 9.

Prosper is on remand at HMP Peterborough, but he appeared for the hearing which lasted less than 10 minutes.
He wore a black t-shirt, dark trousers and black rimmed glasses as he entered his pleas.
The 19-year-old sat with his arms folded when he entered the dock.
As well as admitting the three murders, he pleaded guilty to purchasing or acquiring a shotgun without a certificate, possessing a firearm with intent to endanger life and possessing an article with a blade or point.
He is due to be sentenced on 5 March.

Myth: Lie detector tests are a reliable way to determine if someone is guilty. | Fact: Polygraph tests measure physiological responses like heart rate, blood pressure, and sweat levels but they don’t detect lies. |
The results can be influenced by anxiety, nervousness, or even practiced breathing techniques, making them unreliable. In fact, skilled individuals, including some criminals and spies, have been known to beat polygraphs. Because of this, most courts don’t accept lie detector results as admissible evidence. Instead, investigators use them as a tool to guide questioning rather than definitive proof of guilt or innocence.

The Smallest Details Can Crack a Case
In criminal investigations, even the tiniest overlooked detail can break a case wide open. Detectives are trained to spot anomalies, things that seem out of place or don’t fit the expected pattern.
Take the case of the Golden State Killer. For decades, law enforcement struggled to identify the elusive predator responsible for a series of brutal crimes. But in 2018, investigators turned to a seemingly small detail: DNA evidence that had been stored for years. By uploading the suspect’s DNA profile to a public genealogy database, they were able to trace distant relatives and narrow down their search, eventually leading to the arrest of Joseph DeAngelo.
The takeaway? Never underestimate the power of a minor clue. A misplaced object, a strange alibi, or an old piece of evidence could be the missing puzzle piece that brings a criminal to justice.

Crime Statistic of the Week
False Confessions Play a Role in Nearly 30% of Wrongful Convictions
According to the Innocence Project, nearly 30% of DNA-based exoneration cases in the U.S. involved false confessions. People often assume that no one would admit to a crime they didn’t commit, but factors like intense interrogations, exhaustion, fear, and psychological manipulation can lead to false confessions—even in serious cases like murder.
Take the infamous Central Park Five case. In 1989, five teenagers were wrongfully convicted of assaulting and raping a jogger in Central Park. After hours of high-pressure interrogation, they falsely confessed, despite no physical evidence linking them to the crime. It wasn’t until 2002—after the real perpetrator confessed and DNA evidence confirmed his guilt—that they were fully exonerated.
This statistic highlights a harsh truth: confessions alone aren’t always reliable, and investigators must ensure they are backed by solid evidence. It’s a reminder that justice requires scrutiny, especially when lives are on the line.
