(MISSOULA, Mont.) — Lucius Robbi packed his car a week ago and set out from Horseshoe Bend, Idaho, heading for Missoula, Montana, to start his junior year of college. But the California resident never made it to the University of Montana’s campus.
Friends, family and volunteers are desperately searching across the vast mountain wilderness for any sign of the 21-year-old.
His father, Marc Robbi, said it’s not like his son to go missing.
“We’re very, very worried at this point,” Marc Robbi said.
Lucius Robbi is a skilled outdoorsman who worked summers as a rafting guide. Relatives say he planned to explore on his return trip to college, even bringing along two orange kayaks.
Volunteers scouring through gas station surveillance footage spotted what appears to be Robbi’s green 1997 Subaru Legacy in Garden Valley, Idaho. His cell phone was picked up in the nearby town of Lowman.
From there, the trail goes cold.
Search parties are pouring over maps, calling for more planes and helicopters, hoping someone spots the bright orange kayaks that they hope will lead them to Robbi.
His mother, Tina Glaessner, is holding out hope that her son is okay.
“If anyone can survive out there for seven days, he can do it,” she said.
