The body of Kellie Oakes, 19, was found in the men's toilets at Swindon railway station in February 2002.

A post-mortem examination revealed she had died from a massive heart attack after taking heroin.

A police investigation was launched after CCTV footage revealed she had been with other people just before she died.

A man and a 13-year-old boy were arrested in connection with her death.

'Tragic waste'

But an in inquest in Swindon on Wednesday heard that no-one else was to blame for Miss Oakes' death.

Graphic details the about the last few hours of Miss Oakes' life were recounted in court - a witness described how he shared a toilet cubicle with her as they injected heroin.

The coroner's court heard how as a 16-year-old Miss Oakes had started taking drugs, often paying for her addiction by working as a prostitute.

The court was told that after a spell in prison Miss Oakes managed to give up heroin, only to start taking the narcotic again shortly before her death.
