Dean, convicted in December on two counts of child molestation, was sent to Coastal State Prison in Savannah, according to an email from sheriff’s Capt. Steve Morris.
Coastal State Prison is one of two diagnostic centers in Georgia where convicted felons are evaluated, then given a permanent prison assignment.
Convicted of molesting and exposing himself to his adopted daughter, Dean was sentenced last month to 20 years in prison followed by 20 years on probation.
Dean formerly served on the Columbia County Commission and as mayor of Harlem.
