The family of R&B singer Sean Levert wants the FBI to look into his death following a medical emergency in jail. The family is questioning the methods used by the prison guards on the night of Levert's sudden death.

According to Cuyahoga County jail warden Kevin McDonough, Levert was pounding on his cell door, which resulted in the guards strapping the 39-year-old in a restraint chair in the psychiatric ward. "Our medical people were called and got him to the hospital," McDonough said in a statement. Michael Gibson, Levert's cousin, questions McDonough's account of the events that took place that night.

The 39-year-old Levert died Sunday night at a hospital after he was taken from the county jail where he was serving a one year and 10 months sentence for failure to pay more than $80,000 in child support.

R&B singer Sean Levert, most famously known for being the youngest son of lead O'Jays singer Eddie Levert, has died after falling ill in a Cleveland jail.

The 39 year-old was sent to Cuyahoga County jail last week for failing to pay approximately $80,000 in child support. He died late Sunday night at Lutheran Hospital in Cleveland.

Levert's claim to fame was his stint in the 1980s trio LeVert, which was comprised of Sean, his Grammy-winning older brother Gerald Levert, who passed away on November 10, 2006, and friend Marc Gordon. Read the full story.
