Nicholas Prosper, 19, has been sentenced to life in prison with a minimum term of 49 years for killing three members of his family. He admitted murdering Juliana Falcon, 48, Kyle Prosper, 16, and Giselle Prosper, 13, last month and had plotted to carry out a mass shooting at his former primary school in Luton. In her verdict, Justice Cheema-Grubb said the victims' deaths were 'almost certain to have saved the lives of many children. The community owes them its gratitude, and their memory should be honoured'
