The wealthy jeweller’s son found guilty of murdering Hampshire student Emily Longley in a jealous rage is to appeal.

Elliot Turner, 21, was jailed for a minimum of 16 years last month after he was convicted of strangling the 17-year-old Brockenhurst College student to death in his bed in Bournemouth last year.

The attack was the culmination of a month of anger and upset over his suspicions that she was “twisting his heart” by seeing other men.

He claimed in a trial at Winchester Crown Court he had grabbed aspiring model Emily around the throat but said it was in self defence and she was alive after he had done so.

Now his legal team has lodged an application to the Court of Appeal in a bid to overturn the conviction and sentence of life imprisonment.

A High Court judge will now decide whether to grant Turner leave to appeal.

During the trial prosecutor Timothy Mousley QC said Turner and Emily who met on a double date in December 2010 had a volatile relationship.

The prosecution said Turner used a pillow to smother Emily and then strangled her after she went back to his house to talk things over following a violent argument that night.

Sentencing Turner, juudge Mrs Justice Dobbs said: ''Emily was a lovely, kind, fun-loving girl who brought a ray of sunshine to those she touched.

''That light has been extinguished suddenly and needlessly by you.

''You told your parents you loved Emily - you really do not know the meaning of love.”

She added: ''In my judgment it's apparent you had been thinking of killing Emily and it was only a matter of time before it happened because it's clear she wanted to be free from you and you would not let that happen - if you could not have her no-one else would do.

''You bullied, harassed, threatened and assaulted her.

''You can put away thoughts of champagne, Bentleys and girls and concentrate on the reason you are serving a life sentence.''

His parents Leigh and Anita Turner were also found guilty of perverting the course of justice by trying to cover up for their son.

They destroyed what police say was a confession note from their son and removed a jacket from the crime scene at their home.

Leigh, 54, and Anita, 51, of Queenswood Avenue, Queens Park, Bournemouth, will be sentenced for the crime next Friday at Winchester Crown Court.

The judge, Mrs Justice Dobbs, has already warned the couple they face prison.
