More than 300 volunteers late Monday braved the brutal cold to comb the woods for any sign of a Tennessee 2-year-old who has been missing for five days.
The search for Noah Chamberlin was expected to continue Tuesday in West Tennessee, but only law enforcement would be allowed to search in the daylight, according to the Chester County Sheriff's Office.
Despite temperatures in the teens, "everybody's still keeping faith" that Noah will be found alive, said Leslie Weaver with the Chester County Sheriff's Office.
Weaver told NBC News that "thousands" of volunteers have participated in the search for the young boy since he went missing while hiking in the woods with his grandmother and sister on Thursday.
The volunteers, along with officers from the sheriff's office and the Tennessee Bureau of Investigation, have covered more than 8 miles in the search for Noah, according to NBC affiliate WSMV. But no one has found any sign of the toddler.
"The frustrating side, the bewildering side, is that we've found nothing," said Deputy Sheriff Tom Mapes with the Madison County Sheriff's Department. "All this manpower, all the technical, infrared sightings, hundreds of volunteers going arm-to-arm through all these acres. Nothing, absolutely nothing."
Chester County Sheriff Blair Weaver has said repeatedly that he doesn't believe foul play was involved in the boy's disappearance.
