A 16-year-old boy has admitted kicking a woman to death in a Lancashire park.
Sophie Lancaster was with her boyfriend when she was attacked
Sophie Lancaster, 20, and boyfriend Robert Maltby, 21, were in Stubby Lee Park in Bacup, Lancashire, when they were attacked on 11 August 2007.
At Preston Crown Court a youth, who cannot legally be named, admitted murder, and attacking Mr Maltby.
A 15-year-old youth is due to stand trial for the murder - he denies the charge but admits causing grevious bodily harm with intent.
Murder charges against three other youths - two aged 17 and one aged 16 - were withdrawn.
None of the youths can be named because of their age.
Remanded in custody
The three youths who had the murder charge withdrawn were remanded in custody by Judge Anthony Russell QC, Recorder of Preston, after admitting GBH.
They will be sentenced after the conclusion of the murder trial of the 15-year-old defendant.
A jury is due to be sworn in and a trial, scheduled to last three weeks, is expected to start on Wednesday.
Miss Lancaster died two weeks after the incident. She was in a coma after suffering head injuries and never regained consciousness.
Mr Maltby, an art student, also fell into a coma, but recovered and has since left hospital.
