The widow of R&B singer Sean Levert has filed a wrongful death lawsuit against the City of Cleveland. The “Casanova” singer was one week into a twenty-two month prison sentence for failure to pay more than $89,025 in back child support to the mothers of his children when he collapsed and died in a cell at the Cuyahoga County Jail on March 30th. A recent autopsy report ruled Sean died of natural causes, prompted by heart disease and high blood sugar levels. Angela Lowe has accused prison officials of failing to provide her husband with proper medical care. She is seeking an unspecified amount in damages.
