WHITTINGTON, Ill. -- Authorities in southern Illinois are set to resume searching for an 18-year-old woman who is presumed dead after she disappeared while swimming in Rend Lake.
The Carmi resident was swimming with friends on Monday in the Franklin County lake when she slipped beneath the water.
Rescue crews spent hours searching for the teenager before calling off the effort for the night.
Franklin County Sheriff Don Jones says authorities don't believe alcohol or drugs played a part in her disappearance and don't believe foul play was involved.
The search is set to resume around 8 a.m. Tuesday.
Investigators haven't released the woman's name.
Rend Lake is about 30 miles north of Carbondale.
