Tennessee needs to do a complete search of their records and find out just how many of these licenses have been issued. At the least we will have pictures of the men involved in this fraud.
I recall reading that they do have a record of licenses she processed and are investingating her handiwork for other possible instances of fraud.
These licenses were supposed to be "untraceable" (the names and addresses wouldn't match any real data associated with these men). They may know which IDs are "fake" but it may not offer them much security in apprehending these men (except for the photos).
