(CNN) — The son of one of the world’s wealthiest men is under arrest in London after the body of his American-born wife was found in their home this week, her death unexplained.
Police stumbled into the mystery Monday, when they arrested Hans Kristian Rausing on drug charges.
A search of his home in one of London’s most expensive neighborhoods turned up the body of his wife, Eva, spurring police to arrest him again in connection with the death.
Eva Rausing had struggled with drug addiction for years, an acquaintance said.
“This has been an existing problem for a long time,” said Liz Brewer, who knew Rausing through charity and social circles. “I think the whole thing is a complete tragedy.”
The case puts the multimillionaire couple squarely back in the headlines four years after they were arrested on charges of possessing cocaine and heroin, according to media reports at the time.
Eva Rausing had tried to smuggle a small amount of crack cocaine and heroin into the U.S. Embassy in London, reports said. She and her husband were arrested when police found more drugs at their house.
