19-year-old Nicholas Prosper is being sentenced for killing three members of his family. Prosper shot his mother Juliana Falcon, 48, sister Giselle, 13, and shot and stabbed his brother Kyle, 16, at their family home in Luton on September 13, 2024. Luton Crown Court was told that Prosper had prepared for the murders 'for months' and also had wanted to kill at least 30 schoolchildren. His 'main wish', however, was to 'achieve lasting notoriety as a mass killer, specifically to 'imitate and even surpass other mass killers around the world'. Prosper had conducted in-depth internet research on shootings in the United States of America, Norway, Australia and New Zealand.
