The Alabama Department of Public Health has announced it is sending letters to individuals whose identities may have been taken from department records.
A department spokeswoman says patient records may have been used by a tax fraud operation in Alabama and Georgia. A federal grand jury in Montgomery has indicted 10 residents of both states.
Federal prosecutors say more than $20 million in fraudulent tax returns were filed using identities stolen from various places, including the Fort Benning military hospital in Georgia, a credit card calling center in Georgia and Alabama's prison system.
The health department says anyone receiving a letter who suspects they were a victim should fill out a form in the letter and sent it with supporting documentation to the U.S. Attorney's Office in Montgomery.
