The owners of a southwest Missouri nursing home where eleven people died in a fire have been convicted of healthcare fraud. Robert and Laverne Dupont face 15 years in prison. They’ll be sentenced later.

Robert DuPont had been prohibited from taking part in any federal health care program after his 2002 conviction for conspiracy to defraud Medicare and Medicaid. But the federal prosecutor says he continued to run five long-term residential care homes, with the connivance of his wife.

One of those homes, in Anderson, burned down in 2007, killing eleven residents.
