A coroner has ruled that multi-millionaire Eva Rausing, who lay dead in her London flat for two months before she was found, died from cocaine intoxication.
The 48 year-old wife of Hans Rausing, heir to the Tetra Pak fortune and one of England's richest men, was found "in an advanced state of decomposition" in her central London home on July 9, the BBC reported.
Her husband was arrested earlier that day after being seen driving erratically. His car contained a pile of mail addressed to his wife, and drug paraphernalia.
Police searched the couple's Belgravia home and found Mrs Rausing's body in a second floor bedroom which was blocked by a pile of furniture and sealed shut with gaffer tape.
The inquest heard that housekeepers had been told never to enter the room.
Mrs Rausing's body was discovered hidden under a pile of bedding, with a foil pipe in her hand.
Deputy coroner Shirley Radcliffe said Mrs Rausing died as a result of cocaine intoxication, combined with a heart condition.
"Mrs Rausing's dead was as a result of the dependent abuse of drugs," the coroner said.
She had cocaine, opiates and amphetamines in her blood. In 2006 she was fitted with a pacemaker, but she was killed by a "non-survivable" heart rhythm.
Mr Rausing read a statement to the hearing saying he was devastated by his wife's death.
He heard her slide off the bed while he was in the bathroom.
"She landed sideways and her head was resting on a pillow," he said. "I tried to pull her up. I shouted 'Eva. Eva. Eva.'"
But when he saw she was dead he covered her lifeless body with duvets and bedding.
"I could not cope with her dying," he said, admitting that in hindsight he had not been acting rationally.
In August he pleaded guilty to preventing the lawful and decent burial of his wife, as well as driving under the influence of drugs, and was given a suspended prison sentence.
