The child's mother was located and questioned by authorities after she called police, according to police spokesman Sgt. Larry Moore.

The child was found by a passerby in the area of Haine and Treasure Oaks drives. The child was turned over to Child Protective Services after an initial attempt to locate a parent was unsuccessful, Moore said.
