POWELL JUNCTION, Idaho — Two people were hospitalized after their motorhome veered down an embankment and into the river near the Idaho-Montana border Thursday.

The crash happened at 3:41 p.m. on U.S. 12, about 30 miles west of Powell, Idaho.

According to Idaho State Police, 61-year-old Robert Sanchelli of Helena, Montana was headed east on the highway in a Newmar Ventana motor home pulling 2008 Ford Focus on a trailer. Sanchelli lost control, and the RV veered off the road and over the embankment. 

The motorhome plunged about 200 feet down the embankment and landed in the river, where it caught fire. 

Both Sanchelli and his passenger, 56-year-old Janiel Sanchelli of Helena, were taken to Syringa Hospital in Grangeville by ambulance, then airlifted to St. Joseph Regional Medical Center in Lewiston. 

Both occupants were wearing their seatbelts when the wreck happened. It's not clear what caused the driver to lose control.

The severity of the Sanchellis' injuries has not been released. The crash remains under investigation by ISP.
