A former assistant in a local dental office has been arrested for allegedly stealing funds from her employer.  The Benton woman was arrested following an investigation by the recently-formed Bossier Financial Crimes Task Force.  36-year-old Ginger Maxwell is accused of stealing cash payments received at the dental office where she worked.  She's also accused of altering records so she could steal insurance payments on bogus claims from several fraudulent accounts she had created.  Investigators say the total amount of money taken was more than $19-thousand.  Maxwell was booked into the Bossier City Jail on charges of false accounting, felony theft, and computer fraud.
