Two pickup trucks carrying six South Ripley High School students left an Indiana FFA Association event a few minutes apart and were not racing at the time of the crash that killed three of the teenagers, Indiana State Police said Monday.

Investigators who interviewed two of the surviving teenagers determined neither driver knew the other had left the event Thursday at Hopewell Baptist Church outside Versailles, about 25 miles north of Madison, ISP Sgt. Noel Houze said.

The drivers took different routes from the rural church because one of the trucks was too large to safely turn left onto the road taken by the other vehicle, Houze said.

The parents of the larger truck's driver, 17-year-old Thomas Crawford of Dillsboro, have invoked his right to remain silent and declined permission for investigators to interview him, Houze said.

Crawford was hospitalized after the crash at University Hospital in Cincinnati.

Funerals were scheduled today for Jacob Vogel, 18, of Versailles, and Timothy Bowman, 17, of Osgood.

The funeral for Samantha Hansen, 18, of Holton will be Wednesday at Hopewell Baptist Church.
