British police said Tuesday that Eva Rausing, one of the UK's richest women, was found dead in her West London home, and a man has been arrested in connection with the case. An autopsy was also performed, but the official cause of death is still unclear.
Rausing, 48, was American born. Her husband was Hans Kristian Rausing, heir to the multi-billion-dollar Tetrapak packaging fortune, The Associated Press reports.
According to BBC News, a 49-year-old man has been arrested in connection with her death and on suspicion of drug possession, but British police have refused to answer any questions about the man's identity.
A police spokesman did say, however, that the man was no longer being held at the police station and was receiving medical attention.
There is speculation that the man in question is Eva Rausing's husband, Han Kristian Rausing, but that has not been confirmed.
Eva Rausing had a very public battle with drug addiction, Sky News reports. In 2008, she was arrested outside the US Embassy in London for allegedly trying to bring heroin and crack cocaine into the building in her purse. Police later found small amounts of crack, cocaine, and heroin when they searched the couple's home.
According to The AP, the Rausings were charged with drug possession, but the charges were later dropped.
In a statement Tuesday, Eva's family described her as a "devoted wife for 20 years and a mother of 4 much loved and wonderful children, BBC News reports.
Her parents, Tom, a wealthy Pepsi executive, and Nancy Kemeny, said they were "deeply saddened" by the death of their "beloved" daughter.
Eva's in-laws, Hans and Marit Rausing, also said they were "deeply shocked and saddened" about the tragic death of their daughter-in law, The Telegraph reports.
Hans Rausing Senior, the Swedish father of Hans Kristian Rausing, and father-in law of Eva Rausing, founded Tetrapak. The company has close to 22,000 employees, and is based in 85 countries. According to MSNBC, Hans Rausing Senior is said to be worth $10 billion.
At this time, Scotland Yard is treating the death of Eva Rausing as "unexplained," BBC News reports.
