(CBS/WREG/AP) PARSONS, Tenn. - Police say volunteers searching for 20-year-old nursing student Holly Bobo over the weekend found a "significant" item in the missing person's case, according to a report.
ABC News reports that officials would not disclose what the item was due to the ongoing investigation, but said that the discovery was based on a tip from a phone call.
According to CBS affiliate WREG, close to 800 volunteers reported to help on Friday during daylight, falling short of the 1,500 authorities asked for each day of the holiday weekend.
The station reports that the only item found that's been confirmed to be Holly's is her white lunch bag. That was found a few days after she was seen being led away from her house by a man in camouflage.
The Tennessee Bureau of Investigation did not confirm any new information on Friday and continued to say the DNA tests on blood found outside the Bobo home could not be released.
While police initially believed an abductor dragged Bobo, 20, away as she left for school last Wednesday, investigators now suspect it was a community member who led Bobo into the woods near her home.
Authorities have refused to rule out anyone in the community of Parsons, about 100 miles northeast of Memphis, as a potential suspect.
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.
