[Photo/Agencies] US attorneys general suing Purdue Pharma, maker of the prescription painkiller OxyContin that became addictive for hundreds of thousands of people, are demanding more money after the company's owners boosted more from their personal fortune and offered nearly $4.3 billion to settle thousands of opioid lawsuits. "The Sacklers became billionaires by causing a national tragedy. Now they're trying to get away with it," Massachusetts Attorney General Maura Healey said in a statement Tuesday.
