(CBS/WREG/AP) PARSONS, Tenn. - Though police in Tennessee asked volunteers to hold off in their search for Holly Bobo due to severe storm conditions, investigators reportedly spent Tuesday following leads in the search for the missing 20-year-old nursing student in spite of the weather.
"We don't want to put [volunteers] at risk," said Tennessee Highway Patrol Lt. Brad Wilbanks to the Jackson Sun, "Law enforcement will still be around to respond to anything we find as it comes up."
The paper reports that police were the only ones searching for Bobo yesterday and will continue to be the only ones searching today, because of a forecast of severe storms.
Authorities ask that volunteers return to Decatur County Thursday if Bobo still hasn't been found.
According to the Tennessee Bureau of Investigation, searchers found an additional piece of evidence Friday that may pertain to Bobo, but they are not releasing what it is, reports Reuters.
The new clue was found along the road in the northern part of Decatur County, Tenn.
While police initially believed an abductor dragged Bobo away as she left for school last Wednesday, investigators now suspect it was a community member in camouflage who led Bobo into the woods near her home.
Police say they have begun the process of identifying persons of interest in the case.
Bobo is 5-feet-3-inches tall and weighs 110 pounds. She was last seen around 7:30 a.m. April 13 wearing a pink shirt and light blue jeans. Officials ask that anyone with information contact the TBI at 1-800-TBI-FIND.
