ENGLEWOOD — The body of a passenger apparently thrown some 50 feet from a car crash off Interstate 70 Sunday evening wasn't found until Monday morning.

The body of Chelsey Wells, 19, of Vandalia, was discovered in the 1100 block of Sunset Drive at about 10 a.m. Monday — some 15 hours after the crash, said Ohio State Highway Patrol Lt. Joseph Gebhart.

Sunset is just north of I-70's westbound lanes.

A car driven by Lindsey Bolton, 18, of Vandalia, came off the right side of westbound I-70 at about 7 p.m. Sunday for unknown reasons, Gebhart said. Witnesses pulled Bolton from the car, a 2000 Chevrolet Cavalier, and she was taken to Miami Valley Hospital, where she was listed in "fair" condition Monday afternoon.

What was unclear a day later was how investigators responding to the accident could have cleared the scene Sunday evening without spotting Wells.

Gebhart said there were police officers and paramedics in the area after the accident.

"There were a lot of people out there," Gebhart said. "I can't explain it."

Asked if Wells had been alive after being thrown from the Cavalier, Gebhart said, "I don't believe so."

He added, "We're looking into all aspects of the investigation."

A resident found Wells' body Monday morning in a "heavy brush" area, separated from the car's final resting place by a fence, Gebhart said. For those who first responded to the accident Sunday, there were no indications Bolton had a passenger, Gebhart said.

Deborah Best, a Sunset Drive resident, saw Sunday's accident. On Monday, she was trying to understand how Wells had not been found until Monday morning.

"What if she was alive at the time and she was in the rain all night?" Best said.

"I was kind of upset," added Best, who has an 18-year-old daughter.

The Montgomery County coroner's office put Wells' time of death at 7:10 p.m. Sunday, said an coroner's office employee who would not give his name. He said an autopsy is scheduled for Tuesday.

A man who said he was Wells' father declined to comment Monday.
