The one-vehicle crash occurred just after noon in the 3000 block of East Bemes Road, officials said.
The two 21-year-old women were passengers in a vehicle traveling east on Bemes, when the driver apparently lost control and veered off the road, striking a tree, Will County sheriff's spokesman Ken Kaupas said.
The Will County Coroner's Office said one woman was identified as Sarah C. Shepard, 21, of Park Forest. She was pronounced on the scene at 2 p.m. An autopsy is scheduled for Monday.The second woman, identified by the Lake County, Indiana coroner's office as Cheyenne Cardosi, was pronounced at St. Margaret Mercy Hospital in Dyer, Ind.
Cardosi, of the 12600 block of Alexander Street in Cedar Lake, appeared to have suffered blunt force trauma in the accident, the coroner's office said.The driver, described as a man in his early 20s, was taken to St. James Hospital in Olympia Fields, where he was listed in good condition.
Authorities believe the area’s "hilly" surface may have contributed to the accident but hadn’t ruled out icy road conditions.
Neither alcohol nor drugs were suspected to be a factor in the crash and eyewitnesses said the driver didn’t appear to be speeding, Kaupas said.
