Jenkinson

The 16-year-old was stabbed 28 times by teenagers Scarlett Jenkinson - who also attended Birchwood Community High School - and Eddie Ratcliffe in a park near Warrington, Cheshire in February 2023.

Jenkinson and Ratcliffe, both 15 at the time, lured Brianna to Culcheth Linear Park where she was fatally attacked with a hunting knife.

Jenkinson was sentenced at Manchester Crown Court in December 2023 to a minimum of 22 years' detention, while Ratcliffe was ordered to serve at least 20 years.

The court heard that Jenkinson became "obsessed" with Brianna after joining Birchwood High in October 2022.

The teenagers were discussing Brianna's murder for weeks, detailed in Jenkinson's handwritten murder plan and phone messages found by detectives.
