Deputies say a Hardin County mom knew her 8-year-old daughter was being sexually abused but didn't do anything to stop it.
Camilla Clark was arrested yesterday in Radcliff.
Investigators say two other men- Todd Livingston and Dean Tinsley- were arrested back in July.
They're accused of sexually abusing Clark's daughter.
Investigators say Livingston shared custody of the girl and Tinsley was his roommate.
All three are in jail.
The girl is in child protective services.
