Jeremy Carter, 28, the grandson of former President Jimmy Carter, has died near Atlanta.

The cause of death was not yet known, Fayette County Coroner C.J. Mowell Jr. told the Associated Press on Monday.

Jimmy Carter announced the death Sunday to the congregation of his hometown church in Plains, the Atlanta Journal-Constitution reported. Carter told parishioners his grandson had not been feeling well Saturday and went to take a nap at his family's home in Peachtree City before he died.

Mowell said he was notified of the death early Sunday.

The medical examiner's office of the Georgia Bureau of Investigation consulted with the Fayette County coroner's office and determined that an autopsy was not required, agency spokesman Scott Dutton said. Typically, the agency would do an autopsy if there was evidence of a crime.

In 2005, Mr. Carter, then 18, was sentenced to 30 days of house arrest and three years of probation and ordered to undergo drug counseling after his arrest in a Peachtree City home break-in.
