A Virginia woman whose 5-year-old son was found dead in a septic tank has been charged with felony murder.

Pulaski County Sheriff Jim Davis confirmed Wednesday that Ashley White faces the charge in connection with the March death of Noah Terry Thomas. New River Valley Regional Jail records show that White appeared before a magistrate Wednesday and is being held without bond. Neither Davis nor the records revealed any details.

The new charge was first reported by the Roanoke Times.

White and the child's father, Paul Thomas, already were facing felony child abuse and neglect charges. Paul Thomas also is being held without bond.

The child's March 22 disappearance prompted a nationwide search involving local and federal authorities. He was found in a septic tank on his parents' rental property March 26.
