Nicholas Prosper, 19, shot his family as part of failed plot to kill 30 children at his former primary school

A “truly evil” 19-year-old who murdered his mother and two younger siblings as part of a failed plot to kill 30 children and become the worst mass murderer in British history has been jailed for life with a minimum term of 49 years.

Nicholas Prosper admitted murdering Juliana Falcon, 48, Kyle Falcon, 16, and Giselle Falcon, 13, last month. Their murders were part of a wider plot to storm a morning assembly at his former primary school with a shotgun and “cause the biggest massacre of the 21st century”.
