Emily was found dead in the home of her on-off boyfriend in Bournemouth last year.
The cause of Emily’s death was initially thought to be a drugs or alcohol related until a toxicology report ruled out an overdose. Turner, 20, was later charged with Emily’s murder.
Dorset police also charged the alleged murder’s parents, Leigh and Anita Tuner with perverting the course of justice by destroying evidence and delaying calling the emergency services.
Elliott Tuner and his parents have all pleaded not guilty.
Emily, who was born in England but moved to Aukland with her family soon after, was living in Bournemouth whilst working in Topshop and harboured ambitions of becoming a model.
The case will begin on Monday.
