Mt. Pleasant Police Chief Terry Sammons says human remains found this weekend have been sent to the State Medical Examiner's Office for an autopsy.
He says he's hoping to learn whether the remains are those of 24-year-old Jackie Leigh Douthart, who disappeared last May; or Elizabeth Syperda, who vanished in 2000 at age 22.
A 24-year-old man who was a "person of interest" in Douthart's disappearance committed suicide in July during a standoff with police in western Illinois.
