One of Britain's richest men, Hans Kristian Rausing, has been detained for questioning after his American-born wife, Eva Rausing, was found dead in the couple's multimillion-dollar 5-story mansion on Monday.
The death has officially been reported as unexplained, with The Telegraph addingthat the mother of four may have died of a drug overdose. Eva, 48, was discovered in an upstairs bedroom after her husband was arrested by UK authorities on suspicion of possessing drugs.
Eva faced trouble in 2008 after she allegedly attempted to smuggle drugs into the U.S. Embassy in London. The charges led to a search of the family's home where officials found crack, heroin, and 52 grams of cocaine. "I hope in due course to get back on track," Rausing said at the time, reports ABC News reports. "I am sorry for the upset I have caused."
Rausing and his wife have previously donated large sums of money to anti-drug charities, including the Mentor Foundation, an international program that steers youth away from drug use and abuse, reports the Guardian.
Hans is the heir to billions of dollars generated by Tetra Pak, a company his father founded in Sweden that invented the now-ubiquitous watertight cardboard carton. As of March 2012, Hans had an estimated net worth of $10 billion, according to Forbes.
