Jenan Karagoli, 21, has described how he tried to resuscitate 18-year-old Lady Beth Douglas, the youngest daughter of the Marquess of Queensberry, after finding her unconscious at a house party with needle marks in her arm.
He had been dating the talented young violinist for ten months and was confronted by her grieving father David Douglas, the 88-year-old 12th marquess, days after her funeral.
Lady Beth, who was known to friends and family as Ling Ling, had a history of drug abuse and self harm and was being treated for a range of mental health problems. She was sectioned for six months when she was 17.
The inquest recorded Lady Beth's cause of death as a cardiac respiratory failure and cocaine and heroin poisoning. She was cremated in a Buddhist ceremony in London.
Lord Queensberry has been married three times and had eight children. Lady Beth was the only daughter of his most recent marriage to Taiwanese artist Hsueh-Chun Liao.
