"This community has been amazing. It makes us feel great that people out there care... Trying to find her and bring her home," Duncan said.
More than a thousand people have volunteered to help search the dense woods for any sign of Bobo.
Investigators have not ruled anyone out as a suspect in Bobo's disappearance and are in the midst of analyzing key evidence, although police had earlier said that Bobo's brother and boyfriend are not suspects.
"We have over 250 leads that we're running...the next analysis of a piece of evidence could be a key in solving this particular incident," Gwyn said. "I can tell you that we have not eliminated anyone from this case."
Some of that key evidence includes the 20-year-old nursing student's lunch box found miles from her home. The other evidence being analyzed was found in the woman's driveway and includes blood on the ground and duct tape with blond hair stuck to it.
"We're analyzing that evidence at the TBI [Tennessee Bureau of Investigation] crime lab as I speak and we're hoping...that we will come to conclusion pretty rapidly," Gwyn said.
