The search for a 2-year-old boy missing in the Tennessee woods resumed Sunday with volunteer search teams comprised of only law enforcement members.

Noah Chamberlin, of Pinson, disappeared Thursday afternoon and has not been found despite a massive search.

“We have total faith we’re going to find Noah and bring him home safe,” Chester County Sheriff  Blair Weaver said Saturday, WBBJ-TV reported.

He does not believe the boy’s disappearance was the result of foul play.

He tweeted that Sunday’s search would involve just trained law enforcement.

Noah was hiking with his grandmother and 4-year-old sister in the woods behind his grandmother’s house in Pinson at the time of his disappearance.

“They sat down to talk and she was paying attention to the granddaughter, and when she turned around he was gone,” Tom Mapes, a spokesman for the Madison County Sheriff’s Office told the Jackson Sun Friday.

K-9 units are assisting in the search, which includes the Tennessee Bureau of Investigation. The bureau issued an endangered alert for the boy.

The bureau said Noah is 2-feet tall and weighs 25 pounds. He had on a long-sleeved gray shirt and blue jeans when last seen.

Hundreds of Pinson residents searched the woods for Noah Saturday and then held a candlelight vigil with a symbolic flame of hope, WSMV-TV reported.

“Been cold, wet, muddy, lots of hills, lots of hard terrain, lot of swamps, lot of bottoms. I pray that the boy is good,” volunteer David Terry, one of the residents, told the station.
