The Ohio State Highway Patrol is trying to figure out why 16-year-old Garrett Holmes drove off the road Sunday night.
"It was a one-vehicle crash. The vehicle went off the left side of the road. At this point we don't know why," said OHP Sergeant Donald Pratt.
Holmes was behind the wheel of a 2001 Ford Focus, traveling Southwest on SR 18.
17-year-old Dakota Schaffer was in the passenger seat.
At 9:21PM, just North of County Road 34, the vehicle crossed the center line, and ran off the road.
The vehicle continued into an embankment, grazed the side of a barn, and slammed into a tree where it came to a stop.
The car hit right where Dakota Schaffer was sitting, on the passenger side door.
Schaffer was taken to Bellevue Hospital, then transported to UTMC.
The driver, Garrett Holmes, died at the scene.
Authorities are trying to eliminate possible causes.
"The tire tracks that went off the left side of the road were more of a gradual type. It wasn't as if they were taking evasive action," said Pratt.
A witness was driving in the opposite direction, and told police nothing was seen in the roadway that may have caused the Bellevue teen to swerve such as a deer, or something lying in the road.
Investigators also say texting and driving is not suspected because the driver's (Holmes) phone was found in his pocket.
Police haven't spoken with Schaffer due to his life-threatening injuries he sustained.
Police say that both teens were wearing their seatbelts.
Drugs or alcohol do not appear to be involved.
Items have been left at the site as a memorial. There is a baseball trophy, a golf ball, some candles, flowers, and a box of Little Debbie snack cakes.
Both teens were students at Bellevue High School.
