Two people were taken to the hospital Tuesday afternoon as the result of a crash on U.S. 23 South in Marion County near the Delaware County line.

Troopers from the Marion post of the Ohio State Highway Patrol said Wednesday that at around 2:16 p.m. Tuesday a silver minivan driven by Delaware resident David Nelson was headed south on U.S. 23 near Waldo. Witnesses told troopers that the van drifted off the road and onto the shoulder where it collided with two vehicles parked on the shoulder.

The two occupants in the parked vehicles, Janet Moore and Ronnie Blevins, both of Marion, were not seriously injured in the crash though Moore was taken to the hospital for supervision.

Nelson’s wife and passenger, Diane, was injured in the crash and taken to Grady Memorial Hospital and then Grant Medical Center. Troopers said Diane Nelson is in stable condition with injuries that are not life-threatening.

The Nelsons and Blevins were wearing their seat belts at the time of the crash.

Troopers said an investigation is ongoing. Alcohol and drug use is not suspected in the crash.

U.S. 23 was brought down to one lane for about an hour while tow trucks and medics assisted troopers at the scene.
