An urgent warning has been issued parents about the dangers of intense teenage relationships in an era of social media as an obsessed teenage boy was locked up for a minimum of 17 years for brutally murdering his ex-girlfriend.

Even at the age of 16 Logan MacPhail controlled 15-year-old girlfriend Holly Newton’s life by stopping her going out with friends, demanding to know where she was at all times and changing her social media passwords.

Holly once told her mother that MacPhail had warned her that ‘if he couldn’t have her, then nobody could’.

The grieving mother said: ‘What we didn’t know is he meant it.’

When Holly finally ended the 18-month relationship MacPhail stalked her and, despite police becoming involved, lured her into an alleyway when she was with another boy in January last year and savagely murdered her with a knife he brought with him.
