A University of Montana student whose disappearance sparked a frantic, two-state search died in a car accident, a family friend said.

Lucius Robbi, 21, has been found dead after vanishing more than a week ago while headed from Banks, Idaho, to the University of Montana to attend orientation.

Few details surrounding his death have been released, but Holly Hayes, a family friend who had been helping coordinate the search, posted the grim news to the Finding Lucius Robbi Facebook Page:

"Thank you all for everything you've done Finding Lucius Robbi," she wrote. "This evening he was found. He passed in a fatal car accident. My heart goes out to all who had the pleasure of knowing him and to all those who have been touched by him."

Searchers in Idaho had zeroed in on a green car with a kayak atop it that was seen seen in a gas station surveillance video. Robbi, who told co-workers that he planned to take a drive from Horseshoe Bend, Idaho, to Missoula, Mont., was behind the wheel of a green 1997 Subaru Legacy. He was traveling with two kayaks on top of the car.

Authorities worked to narrow their search, and considered a video from a Chevron gas station a breakthrough. A screen grab showed a similar car and one orange kayak.

But a friend working in the search told Fox News' "Fox and Friends" that there are concerns that the car in the photo was not a match. To be sure, the car and kayak matched the color description, but the car seen in the video appeared to be travelling with one kayak. Robbi was carrying two.

His last contact with his family was at about 2 p.m. last Tuesday and he was supposed to attend a university orientation, but never arrived.

Robbi had been working at a local rafting company, Cascade Raft and Kayak, in the town of Horseshoe Bend.
