'The worst case of post natal depression I've ever heard of'. That's how a coroner has described the case of a woman from Wiltshire whose battle with the illness led to her tragic death.
Emma Cadywould's body was found beside a railway line in South Marston six months after the birth of her son. She had been struck by a high speed train.
Her family say they were pleased the inquest verdict was not suicide - because this will allow them to take the case further. Martin Dowse explains.
