Logan MacPhail, then aged 16, stalked Holly Newton for an hour through Hexham, Northumberland, before knifing her 36 times in an alleyway.

MacPhail was convicted of murder following a trial at Newcastle Crown Court in August and sentenced at the same court yesterday.
Last month the judge lifted a reporting restriction which had prevented the media from identifying him due to his age.
