LAFOLLETTE, Tenn. (WVLT) -- A woman who was already identified as a person of interest in the death of a newborn baby found dead in a garbage bag just outside of LaFollette city limits faces murder charges in connection with the infant's death.

Wanda Cieslak was charged with First Degree Murder and Aggravated Child Abuse and Neglect, Chief Jimmy Jeffries announced on Tuesday. Jeffries added that while they are still awaiting the final results of the autopsy, the preliminary report could not find any reason the child was not born alive and healthy.

The newborn was discovered wrapped in a blanket inside a bag shortly after one o'clock early Friday morning in the 100 block of Hatmaker Drive. Officials believe the baby was born in a home in the 500 block of South Indiana Ave. that was quarantined fro methampetamine production on October 11. They think the baby was born two days later.

The Tennessee Bureau of Investigations is continuing to perform polygraphs on individuals believed to be involved in the case, with Jefferies stating, "This case is still being worked to full investigation and did not stop with Cieslak;s arrest."

Cieslak was already in custody after being picked up on a bench warrant on Friday.
