Testing performed at the Smithsonian Institute has determined where Racine County’s Jane Doe may have spent several years of her life.
The girl was found in 1999 at the edge of a cornfield on 92nd Street in the town of Raymond in Racine County.
Her identity has remained a mystery, but in 2013, her body was exhumed.
Chemical isotope testing performed by the Smithsonian on a sample of her hair and bone suggest she may originally have been from or spent several years of her life in Alaska, Montana or portions of southern Canada.
