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 last seen on Tuesday leaving Cascade Raft and Kayak and expected to arrive Wednesday in Missoula, Montana, for school orientation, but never arrived.
Robbi told friends he was planning on pitching a tent Tuesday night, so campgrounds are a main focus.
Law enforcement in several counties and dozens of volunteers are searching the route to Missoula through Riggins and Stanley.
"I was in the first search group on Thursday," said Lauren Megaw, Robbi's coworker. "We're all really close and it's been horrible."
Robbi is driving a green 1997 Subaru Legacy with California plates and one or two kayaks on top. Surveillance video taken on Tuesday afternoon in Garden Valley showed a similar car, but Boise County Sheriff deputies say they don't believe it is his. Investigators say that the video shows only one kayak, and in the opposite direction that he would have tied it down.
Deputies say dozens of leads suggest Robbi may be in the Glacier Park area. His phone was also tracked in Smiths Ferry.
A family friend spoke to KTVB over the phone Sunday.
"We're just so worried about him," said Holly Hayes. "Pray for his safety. Lucius is a stand-up guy. It's totally out of character to be missing like this."
Law enforcement from Boise, Custer, and Lemhi counties are all taking part in the search effort. An aerial search was conducted on Sunday.
The search has escalated and friends urge to keep a lookout for the car and Robbi.
"That's the main goal right now," said Hayes. "The more eyes the better. People out hunting, whatever they're doing outdoors, we would greatly appreciate it."
It's unclear which route Robbi might have chosen to drive to Montana, but Boise County deputies believe Robbi may have traveled through the Riggins area on Highway 95.
Robbi was working at a local rafting company in Idaho.
A Facebook page has been set up where family and friends are keeping up with developments in the search.
"It's getting scarier every night that comes, another night, knowing that he's out there," Hayes said.
