Triple murderer will not be given whole-life order, Court of Appeal rules

Prosper was jailed for life with a minimum term of 49 years in March after he murdered 48-year-old Julianna Falcon, 13-year-old Giselle Prosper and 16-year-old Kyle Prosper at their family flat in Luton, Bedfordshire, on September 13 2023.

The 19-year-old was also sentenced for weapons offences, having plotted a mass shooting at his former primary school.

The Solicitor General referred Prosper’s sentence to the Court of Appeal in April, with barristers telling a hearing in London that a whole-life term was a “just punishment” for the “exceptional” crimes.

Barristers for Prosper, who is due to be released in his late 60s at the earliest, said the sentence “cannot be said to be unduly lenient”.

In a ruling, the Lady Chief Justice Baroness Carr, sitting with Mr Justice Goss and Mr Justice Wall, said that Prosper’s sentence was “itself a very severe sentence for a 19-year-old”.
