The man accused of murdering his New Zealand girlfriend in a jealous rage has been accused in court of not showing remorse over her death.

But Elliot Turner says that he did show remorse to his mother and to friends, and said he had been "cut up" about the death of aspiring model Emily Longley.

The prosecution alleges that the 20-year-old Turner strangled Emily in his bedroom at his home in Bournemouth, Dorset because he was angry that she had been seeing other men.

Turner, who denies murder and perverting the course of justice, said Emily attacked him repeatedly in the room and he grabbed her around the neck for five or six seconds to defend himself.

He then went to sleep and found 17-year-old Emily dead in his bed when he woke up on May 7 last year.

Giving evidence for the third day at Winchester Crown Court, Turner told the jury he loved Emily and that she had loved him.

Under cross-examination he denied he had been manipulative or obsessive about Emily during their "volatile" relationship.

Turner said he did not believe he was responsible for her death and told the jury that he did tend to exaggerate.

He was asked why he used abusive words in text messages to friends when referring to Emily when he said he loved her.

Turner said: "Just because you call someone a c*** does not mean you don't love them."

He said he slept with three girls during his relationship with Emily.

Earlier the prosecution alleged that Turner "went absolutely nuts" at the end of their short, volatile relationship.

When arrested he had his passport in his pocket, the court heard.

Computers seized from his home showed Google searches had been made for "death by strangulation" and "how to get out of being charged for murder".

Police bugged the family home and charged Turner's parents Leigh Turner, 54, and Anita Turner, 51, with perverting the course of justice.

Emily was born in Britain but her family emigrated to New Zealand when she was nine. She had returned to live with her grandparents in Bournemouth to study.
