Federal prosecutors say 46-year-old Shirl Robinson obtained the names, birth dates and Social Security numbers of children and sold them to a Philadelphia tax preparer. They alleged Wednesday that information was then used to list bogus dependents on income-tax filings.
A superseding grand jury indictment filed Tuesday says Robinson, of Darby, made about $650 for each child, whose parents or guardians wouldn't be claiming them as dependents.
Robinson's public defender didn't immediately respond to an email seeking comment.
Authorities say the investigation is continuing.
