HORSESHOE BEND, Idaho -

The Boise County Sheriff's Office is asking for help finding a 21-year-old University of Montana student last seen in Horseshoe Bend in southwest Idaho.

The last contact Lucius Robbi of Orleans, California, had with his family was at about 2 p.m. Tuesday.

He was supposed to attend orientation at the school on Wednesday but never arrived.

He's driving a green 1979 Subaru Legacy with California plates and one or two kayaks on top.

It's unclear which route Robbi might have chosen to drive to Montana.

Robbi was working at a local rafting company in Idaho.
