A wealthy jeweller and his wife who disposed of evidence to help cover up after their jealous son murdered his girlfriend, aspiring Kiwi model Emily Longley, have been jailed for 27 months each.

Elliot Turner, 20, was found guilty by a jury at Winchester Crown Court in May of murdering 17-year-old Emily in his bed after going "absolutely nuts" in a jealous rage.

Sentencing him, Justice Dobbs said he had "bullied, harassed, threatened and assaulted" Emily to control her as his "trophy" girlfriend.

And she told him to put away thoughts of "champagne, Bentleys and girls" as she sentenced him to life imprisonment and told him he would serve at least 16 years in jail.

His parents Leigh, 54, and Anita, 51, were sentenced on Friday at the same court after being found guilty of perverting the course of justice.

They helped to cover up the crime by destroying a confession letter from their son and taking away vital evidence after the killing at their home in Bournemouth, Dorset, in May last year.

Their son was also sentenced to nine months, to run concurrently, for perverting the course of justice.
