Teenager pleads guilty to murdering family and planning shooting

Nicholas Prosper, an 18-year-old, has pleaded guilty to murdering his mother and siblings in Luton last September. He was also planning a mass shooting at a primary school. Authorities found a loaded shotgun and cartridges at the scene. Investigators discovered Prosper's troubling online history, which included visits to violent content and discussions about mass shootings. He had previously been removed from a website for inappropriate comments about minors. No charges were filed regarding this material. In response to the incident, local schools have increased security measures. Luton Borough Council is conducting additional security assessments to address community concerns. Prosper's sentencing is set for next week.
