The trial of the man accused of killing aspiring New Zealand model Emily Longley has been told he woke to find her "cold and grey", but proceeded to get ready for work.

Emily's friend, Carla Simons, told the Winchester Crown Court on Thursday that Emily's boyfriend, Elliot Turner, had found her unresponsive on the morning of May 7, 2011, the Bournemouth Echo reports.

Turner had told police he and Emily had argued the night before and she had attacked him, and that when he woke up beside her she was dead. An ambulance, however, was not called until after 9am.

Carla, 18, said: "He said he went to grab her arm and she was cold and grey.

"He said he presumed that she had just passed out. Then he realised that was not normal so then he started to shake her to try to wake her up."

Carla said Turner had told her this when she bumped into him outside the Bournemouth jewellery store owned by his parents and where he worked, after Emily's death.

Turner, 20, is charged with murdering Emily, 17, at his home in Bournemouth, Dorset.

He denies murder and perverting the course of justice between May 6 and July 21, 2011.

Turner is accused of failing to telephone the emergency services and attempting to persuade his mother to change her account to the police.

Turner's parents Leigh Turner, 54, and Anita Turner, 51, are also in the dock accused of covering up for their son by destroying evidence and taking items away from the scene of the death. They both deny perverting the course of justice.

Emily, who was a student, had been born in Britain but her family had emigrated to New Zealand when she was nine. She had returned to live with her grandparents in Bournemouth while studying at college when she died.
