Cummins faces state charges of aggravated kidnapping and sexual contact with a minor, as well as a federal charge of taking a minor across state lines to have sex.
He is also facing a child trafficking charge for grooming and kidnapping Elizabeth. The Tennessee Bureau of Investigation believes Cummins "may have been abusing his role as a teacher to groom this vulnerable young girl for some time in an effort to lure and potentially sexually exploit her."
Cummins has two children with his wife, who has filed for divorce.
Elizabeth's mother, Kimberly Thomas, is also facing charges of child abuse and child neglect to five of her 10 children - Elizabeth included.
The allegations against her include that she beat her children, threw them downstairs and locked them in a basement, reports The Tennessean.
