Skeletal remains found in Union County

JONESBORO, Ill. -- Authorities in Southern Illinois' Union County are trying to identify human skeletal remains found near a freeway.

Authorities plan an autopsy on the remains found by Illinois State Police troopers.

Investigators say there's no immediate evidence of foul play.

The discovery comes less than a week after state police announced that forensic testing helped them identify the skeletal remains found in November 2005 in a ditch in nearby Massac County.

Authorities say 72-year-old Frances Graham of Tellico, Tenn., was kidnapped in September of that year. That homicide investigation continues.
