Triple murderer Nicholas Prosper should be given a whole-life order for the “exceptional” killings of his mother and two siblings, the Court of Appeal has heard.
Prosper was jailed for a minimum term of 49 years, less 188 days already spent in custody, in March after admitting killing his mother, Juliana Falcon, 48, sister Giselle Prosper, 13, and 16-year-old brother Kyle Prosper at their family flat in Luton, Bedfordshire, on September 13 2023.
