CUMMING — Two workers from a Cumming weight-loss center remain in custody after their arrests last week in connection with a prescription drug fraud investigation. Teresa Vickers, 52, and Mary Wysong, 69, were arrested July 8 and charged with possession of pre-signed blank prescriptions, practicing medicine without a license and distributing prescriptions without a license. “Vickers is under an $82,500 bond and Wysong is under a $33,000 bond,” said Doug Rainwater, a spokesman for the Forsyth County Sheriff’s Office.
