Robertas Lukosius, 34 and Lauras Boiko, 30, both lived in Wisbech when Alisa Dmitrijeva, 17, went missing in the late summer of 2011.

They were were called to give evidence before Norfolk's assistant coroner, at King's Lynn County Court, but could not be contacted because their whereabouts are now unknown.

Alisa was last seen in the Friars area of King's Lynn, in August 2011. her badly-decomposed body was found on the Royal Estate, beside a shooting covert between Sandringham and Anmer, on New Year's Day, 2012.

Details of the police investigation into her death emerged for the first time. Detectives made repeated appeals to trace a bottle green Lexus car, in which they believe Alisa of Railway Road, Wisbech, travelled to a beach party at Snettisham.

In a statement taken after he was arrested on suspicion of kidnap and murder, in May 2012, Lukosius said he had owned the Lexus for six weeks. he said he had previously met Alisa to buy cannabis and had dropped her off at an Asda on August 31, 2011.

Boiko said they dropped her off at the supermarket and that was the last he saw of her. He described as 'friendly and talkative.

But Det Con Jeremy Pitt told the court that the men 'lied' about dropping Alisa off at the supermarket. He said that Boiko's wife was arrested for peversing the course of justice after it was proved she was not telling the truth about what time he came home.

He said that phone records proved that Alisa was at Snettisham beach on August 31, before being taken to where her body was found.

Det Con Pitt added a taxi driver took the men from the beach to the local petrol station to fill up a can and drove them back to the same location.

He said: 'Fibres found in the boot match her bra and hair. Turnip and wheat seeds were growing adjacent to where her body was found and a shell was found near her body.'

He also said that on a sat-nav found in the Lexus had Wisbech programmed as its destination - suggesting that the men had become lost.

The court heard Alisa's body was found on New Year's Day 2012 by Stephen Sharp, who was walking with his eight-year-old son Noah when they stumbled across her remains, which were surrounded by growing ivy.

Forensic pathologist, Dr Nathaniel Carey said that the body had lain between one to four months but the cause of death could not be ascertained due to the body being badly decomposed.

The court was told the Crown Prosecution Service said that there was not enough evidence to charge the men and they were released without charge.

Following the hearing, Det Insp Marie James, of the Norfolk and Suffolk Joint Major Investigation Team, said the case would remain open.

'We are certain there are individuals out there who know how and why Alisa died,' she said.

'Our investigation into her death will remain open and I would reiterate my message to anyone who may have information to have the courage to come forward.

'Alisa was a young woman on the cusp of adulthood whose life was cut short. Her family want answers and we need to find those responsible or involved in her death.

'As over three years have passed now since Alisa disappeared, we hope that allegiances may now have changed and people with important information, if they didn't have the confidence at the time, will now feel able to come forward.'

Anyone with information about Alisa's death is asked to contact the Major Investigation Team at Norfolk Constabulary on 101 or visit their local police station. Translation services are available on request.
