A lieutenant at the Savannah Regional Youth Detention Center was caught using a state fuel card to buy gas for his own car, and he told the GBI he got away with it 40 times. The Department of Juvenile Justice fired him last March. The incident is revealed in a new report from the state Inspector General, obtained by Atlantaunfiltered.com.The report documents how the worker used employee identification numbers belonging to other people. The IG says DJJ was slow to review fuel transactions and look for abuses. State procurement rules have changed since March.
