Skeletal remains including a skull, a jaw, and three other bones were located in a wooded area on Nov. 25, 1984, according to state police and the National Missing and Unidentified Persons System.
The bones were discovered by a resident's dog behind a property at 456 E. Collom Street, authorities say. Police were never able to locate the rest of the victim's remains.
Investigators believe the remains belonged to a black girl between 4 and 6 years old. She is thought to have died about one year before the bones were found, according to the Doe Network.
In the years since her discovery, authorities have circulated multiple renderings of her possible appearance based on the skull.
