The Cuyahoga County Coroner's office said Sean LeVert's body was taken to the hospital from the Cuyahoga County Jail.
Late Monday afternoon, the Cuyahoga County Sheriff's Department released a statement that said, in part, "Mr. Levert was remanded to our custody on Monday, March 24, after being sentenced to the state prison system by Cuyahoga County Judge Nancy M. Russo for criminal non-support."
The amount is allegedly $80,000.
"He was sentenced to two, consecutive 11-month sentences and was to be turned over to the Ohio Department of Rehabilitation and Correction as early as Tuesday, April 1."
Levert spent five days in the county jail's general population before appearing to display some bizarre behavior, the sheriff's department said, and was then put under observation.
On Sunday evening, Levert was placed in restraints without resistance and was found in distress approximately 20 minutes later, jail officials said.
The matter is under investigation by the Sheriff Department's Detective Bureau and the Coroner's Office.
Jail officials say they were not aware of any pre-existing medical condition.
Sean LeVert, 39, of Streetsboro, was the younger brother of Gerald LeVert and was a member of the band "LeVert."
The cause of his death is not immediately known. Coroner's spokesman Powell Caesar says an autopsy on Sean LeVert's body will likely be done today.
Powell also said toxicology tests are being done but those results are usually not expected back for 4 to 6 weeks.
LeVert is an R&B group that was formed in Cleveland in 1984 with Sean and Gerald Levert, the sons of O'Jays founder Eddie Levert, as well as Marc Gordon.
Gerald Levert, a Grammy award winner, was 40 when he died in his sleep at his home in Newbury in November 2006.
The LeVert family has a street named after them in their native Canton.
