All our stories from the Emily Longley murder trial

Turner was jailed for life in May last year after being convicted of killing 17-year-old Emily in his bed at the family home in Queenswood Avenue, Queens Park, Bournemouth, on May 7, 2011.

He was told he would have to serve a minimum of 16 years behind bars before he would be considered for parole.

The trial at Winchester Crown Court heard the attack was the culmination of a month of anger and upset over suspicions that Emily was “twisting his heart” by seeing other men.

Turner admitted grabbing Emily by the throat during an argument but claimed it was self defence and she was alive afterwards.

Turner's parents, Leigh and Anita Turner, were also convicted during the same trial of perverting the course of justice by destroying a confession note from Turner and removing a jacket from the scene. They were each jailed for 27 months.

Emily was living with her grandparents in Southbourne and studying for a business diploma course at Brockenhurst College when she died.
