Hans Kristian Rausing pleads guilty in London court to preventing proper burial of his wife

LONDON - A judicial official says that Hans Kristian Rausing has pleaded guilty to preventing the proper burial of his wealthy wife Eva Rausing.

A spokesman for Britain's judiciary says that Rausing, , whose father made billions selling his stake in the Tetra Pak drinks-carton empire, pleaded guilty Wednesday to charges of "preventing the lawful and decent" burial of his 48-year-old wife. She spoke on condition of anonymity because of office policy.

Eva Rausing's body was badly decomposed and covered by layers of clothing and garbage bags when police found it in early July in the luxury London home she shared with her husband.

The discovery followed her husband's arrest on suspicion of drug possession after he was spotted driving erratically.

Police have said that an autopsy failed to determine the cause of her death.
