Noah Chamberlin was last seen hiking in the woods with his grandmother and older sister. His grandmother said she was distracted for a minute and turned around to discover he was gone.

Authorities previously welcomed the help of hundreds of volunteers to search for the boy. For a brief time, officials reported six of those volunteers had also gone missing, though WMC-TV reported they were waiting for help after one of them was injured.

As of Sunday morning, the Chester County Sheriff's Department said only certified law enforcement officers were allowed to continue the search.

"We're 100 percent it's a search and rescue mission," Chester County Sheriff Blair Weaver told WBBJ. "We have total faith we're going to find Noah and bring him home safe."
