UNIONTOWN, Pa. -- State Troopers cracked an eight-year-old cold case by charging a Uniontown woman with killing her own baby.

Fishermen found the body of a baby girl wrapped in a flannel shirt in a backpack that was in a plastic bag in the waters of the Cove Run Creek in North Union Township in June 2000.

An autopsy of the victim, "Jane Doe," was performed at St. Francis Hospital, and it was determined that the infant was approximately 8 to 8 1/2 months gestation and appeared to have been viable at the time of delievery.

Through mitochondrial DNA analysis and maternity-style analysis, investigators determined that Sarah Hawk, 25, of Uniontown, is the biological mother of the infant child.

They charged Hawk with criminal homicide and concealing the death of a child.

She was arraigned and remains in the Fayette County Prison without bond.
