The case
Nicholas Prosper murdered his mother Juliana Falcon and his siblings Kyle and Giselle at their Luton home on 13 September 2024. He had obtained a shotgun using a false firearms certificate.
Evidence and court findings
The investigation uncovered plans for a school shooting. Prosper admitted the three murders and associated weapon offences. At sentencing, the judge considered the overall offending, his age and guilty pleas, deciding on a substantial minimum term rather than a whole-life order.
The sentence
On 19 March 2025, Luton Crown Court imposed concurrent life sentences. The 49-year minimum became 48 years and 177 days after remand credit. On 16 July 2025 the Court of Appeal refused the Solicitor General’s attempt to obtain a whole-life order, leaving the sentence in place.
Sources and case status
Includes the 16 July 2025 appellate decision refusing the reference seeking a whole-life order. The life sentence and finite minimum remained.
