The Advocate reports (http://bit.ly/VhBZFs ) Jessica Hebert (AY'-bair), of Picayune, Miss., is being held on one count of simple kidnapping in Pearl River County.
Iberia Parish sheriff's Capt. Ryan Turner says the 4-year-old was spending the night with Hebert last week when Delcambre (DEL'-kuhm) police arrested and briefly jailed the girl's mother for allegedly failing to appear in court for a traffic violation.
Deputies say Hebert allegedly traveled back to Mississippi and refused to return the child after the mother was released from jail.
Detectives traveled Sunday to Mississippi and have returned the child to her mother.
It was unclear whether Hebert has an attorney.
