A 13-year-old boy who had been reported missing four years ago was discovered alive, hidden behind a fake wall of a home near Atlanta, and reunited with his mother early Saturday, police said.

Five people living in the home in Jonesboro, Georgia, 30 km south of Atlanta, were taken into custody, among them the boy's father, Gregory Jean, 37, and an adult female, said Sgt. Kevin Hughes of the Clayton County Police Department.

Jean and Samantha Joy Davis face charges of false imprisonment, cruelty to children and obstructing an officer, he said, adding that three juveniles also in the home were facing obstruction charges.
