As of about 5 p.m., authorities estimate almost 1,000 people have assisted in the search for Noah in the past 28 hours including volunteers and law enforcement.
David Castellaw arrived this morning from Jackson along with about 290 others from West Tennessee to help in the search for the missing toddler.
As he and the others loaded the buses to go search the 600-acre area where the boy was last seen, Castellaw was still hopeful for a positive outcome.
Mapes said law enforcement teams searched and cleared ponds in the area earlier today.
Mapes said, and items from Noah's bed were gathered for police dogs to try to catch his scent.
The Tennessee Bureau of Investigation has asked residents who live near the search area to also search their properties. "The TBI has announced they would like to issue a challenge for anybody that lives within a five- to six-mile radius of the site to go out and check their areas like barns, cars, sheds anywhere a young child could hide because he could have gotten scared during the night," Mapes said.
"There is a lot of deep terrains. There's several, several creeks to cross. It's just bad. It's real hilly and real, real woody. Some of it has a lot of briers and stuff.
"We're trying to follow the path of least resistance because we figure a 2-year-old is not going to go through briers and stuff," he said. "It's just so hilly. It's hard to believe a 2-year old would walk miles."
He was last seen wearing a long-sleeved gray shirt and blue jeans.
I just look at my little girl who is the same age as Noah and I just cant fathom how his parents must be feeling. The thought of my 2-year-old out at night all alone, cold and scared.. No, just no. I would be a mess.
