Army combat medic Kelli Bordeaux has been missing four months. She was last seen leaving the Froggy Bottoms bar April 14.
Initially hundreds of people helped in a massive search of the area, but searches haven't turned up anything. The number of volunteers has dwindled to a dozen.
"It's like we have no leads, nothing right now. It's kind of frustrating, but when it comes to Saturday morning I wake up like 'let's do this'" volunteer James Warwick said.
Volunteers meet each Saturday morning at 8 a.m. in the Food Lion parking lot at the Andrews Commons Shopping Center. Organizers said the searches normally last three to four hours, but they are unsure of how many will turn out Saturday.
"We need people that can go out on foot. We cover two to two and a half miles a day, and where we are searching right now is not as dense as what we have searched before. It's an easier walk, but it's a lot of land," search organizer Tina Turner said.
Police say they are treating Bordeaux's disappearance as missing person's case.
