NASHVILLE, Tennessee (Reuters) - Investigators said Monday they have discovered a clue that could lead them to Holly Bobo, the Tennessee nursing student missing since April 13.

"We did find an additional piece of evidence that we may link to Holly, but we're not releasing what it is, of course," said Kristin Helm, spokesperson for the Tennessee Bureau of Investigation.

She said the new clue was found along the roadside in the northern part of rural Decatur County. Searchers focused on that area on Sunday and were expected to return Monday after a morning briefing of the various law agencies involved in the search.

Bobo, 20, was last seen by her brother, who reported that a man in full camouflage gear led her into the woods near the family home in Darden. He has told authorities that he thought it was her boyfriend and didn't suspect anything until he went outside and found blood.

Bobo is the cousin of country singer Whitney Duncan.
