(CBS)- Investigators may have a better sense of -- who -- is behind the dissappearance of a missing college student from Decatur County.
It is now day 5 in the search for 20 year-old Holly Bobo.
A TBI spokesperson confirmed on Saturday, the search for a missing college co-ed is just that: a search; not a recovery effort, at least not yet.
TBI spokeswoman Kristin Helm confirmed to NewsChannel 5 that an undisclosed amount of blood was, in fact, found at the crime scene Wednesday morning. She said that blood sample is currently undergoing DNA sampling, to confirm whose blood it is. Helm also said both Holly Bobo's brother, Clint, and her boyfriend have been officially cleared as suspects.
Holly Bobo was abducted from her home by a man wearing camouflage Wednesday morning. The searchers returned Saturday morning looking for signs of the 20-year-old a day after finding her lunchbox.
Her brother last saw her Wednesday morning walking into the woods with an unknown man. The TBI does not believe she went willingly.
