Harrison Co. authorities say Jessica Stringfellow, 24, admitted to the act during an interview.
Stringfellow was booked into the Gregg Co. Jail and charged with a single felony charge of "Sexual contact/intercourse with a person in custody" and "Prohibited substances and items in a correctional facility".
Stringfellow's bond has been set at $15,000 and investigators say further charges may be filed in this case.
