One week after 20-year-old Holly Bobo disappeared from her Decatur County home, authorities called off volunteers for a day as they revisit their search plan.
TBI said that DNA tests on the blood found outside the Bobo home have come back, but they cannot release the results.
Investigators did not release other new information on Wednesday.
In the past week, thousands of volunteers have helped look for any clues of Holly Bobo, but they are being asked to stay home on Thursday.
Lt. Brad Wilbanks of the Tennessee Highway Patrol said, "The volunteers you can tell they get tired and sometimes maybe careless. We've had a few minor injuries. That's why we're wanting everyone to rest up, clear their minds and come back regrouped and focused."
Some people searching over tough terrain have sprained their ankles. Four people had to be located with a helicopter, and another woman suffered an abrasion to her neck from a cable.
