PINSON, Tenn.—More than 200 emergency responders are searching the woods where two-year-old Noah Israel Chamberlin was last seen on Thursday around 1:30 P.M.

It has been around 72 hours since the toddler went missing after authorities say his grandmother said they were in the woods behind the house playing with his four-year-old sister.

Tom Mapes with the Madison County Sheriff’s Office said in a brief with the media Sunday morning that the Chester County Sheriff’s Office requested help from across the state from law enforcement, first responders, and other trained personnel.

Mapes said that a pack of search and rescue dogs from Florida arrived Sunday morning to assist in the search.

On the fourth day of the search Mapes says they are still confident this is a search and rescue mission.

He says the rain on Thursday night has hindered their ability to track a scent or trail of Noah. The terrain has also been causing multiple problems for law enforcement and volunteers with many reports of injuries of the searchers.

When asked about deer cameras, Mapes denied there was anything useful on the cameras and is currently checking to see if there was any footage of the family on them.

Mapes said the family has been active in the search which is why they have not issued a statement to the media about the search for Noah.

In a press conference on Saturday night with the Chester County Sheriff Blair Weaver he said,”We have total faith we’re going to find Noah and bring Noah home safe.”

Sheriff Weaver reiterated Saturday night that he does not believe there is anything criminal about Noah’s disappearance. When the Sheriff was asked about the grandmother’s account of what happened Thursday, Weaver said he believes her and the entire family is cooperating in the search.

Weaver is also discouraging the public to start or listen to rumors spread on social media and to rely on information directly from the department.

The volunteer search has been suspended since Sunday morning around 7 A.M. Authorities are unsure if and when more volunteers will be needed.

More than 2,000 volunteers from across the Mid-South have worked around the clock to aid in the search to find Noah.

An Amber alert has not been issued to due the fact they believe he is still missing. Mapes said Amber alerts are for children they believe to be abducted.

Noah was last seen wearing a gray T-Shirt and blue jeans. Deputies say he is around two feet tall and weighs around 25 pounds.
