NEAR BRUNSWICK, Ga. -- Investigators conducted a new search for missing 6-year old Christopher Barrios, Jr. that continued even after the sun set on Wednesday evening.

Police scoured a wooded area and searched a pond about a mile away from where neighbors last saw Christopher playing on a swing set in the mobile home park in which some of his family member's live.

Investigators said the two men most recently arrested in connection with the boy's disappearance, sex offender George Edenfield's 58-year-old father, David, and a friend of the family, Donald Dale, 34, were brought out to the woods to help in the search.

"If someone is cooperating with us and they're willing to go out there and show us what they said earlier about where we could expect to find Christopher and if we can't find him on our own, we go out there and ask them, 'Go ahead and show us.' That's what they were doing, and we're in the process of doing that," said Glynn County Police Chief Matt Doering.

Earlier this week, police arrested Edenfield's 57-year-old mother, Peggy, on charges of giving false statements, obstruction of an officer and concealing the death of another person -- but Doering was quick to say that filing that charge does not mean that police believe that Christopher is dead.

George Edenfield has been in police custody since last Friday on charges of violating his probation after police said he had unsupervised contact with Christopher.

All three Edenfields and Dale are being held without bond in the Glynn County jail.

Doering said they violated the law "by them telling us of their personal knowledge of Christopher having been killed, or at least abducted, and failing to inform us."

On Wednesday afternoon, police again embarked on a search of the mobile home where Edenfield and his mother live across from the home Christopher's grandmother.

They said they were looking for some objects that might somehow be connected to the missing boy, but they would not elaborate any further.

"The information they gave us that led us to go search the other area gave us some information that we didn’t have before, and that led us to believe there was some evidence that we would want to take out of here that we didn’t recognize as evidence the first time we were here. So, we came back with a second search warrant and we are now taking the evidence that we want to take," Doering said.

Later, Channel 4's Melanie Lawson reported investigators carried several bags of evidence from the Edenfield's mobile home.

Also on Wednesday, police said they were looking into other people in their investigation. Police said the people are not suspects, just people with whom they need to speak.

Police said they still believe Christopher may be alive.

"I'm convinced enough to keep looking. If we didn't have any degree of confidence at all, we wouldn't be here," Doering said.

They said Christopher was last seen on Sunday at a Dollar General with a white man with long hair and thus the search area has expanded.

At daybreak Thursday, officers are expected to re-start their search of the nearby pond.

"Anyone who has my son, I want them to know I love my son, I miss him and I want him to come home," Mike Barrios, the boy's father, said Tuesday as he sat outside his trailer, feeding sliced sandwich meat to a stray tabby cat his son had named Jimmy.

Sue Rodriguez, Christopher's grandmother, who lives in the same trailer park, said she last saw him Thursday after school when the kindergartener ran into her home, shrugged off his jacket and book bag onto the coffee table, grabbed a lemonade and headed outside to play.

The boy's father and grandmother described him as shy, but with a toothy smile that showed off the silver caps covering his front teeth. Like many boys his age, he loved video games and superheroes such as Batman and Spider-Man.

Rodriguez said she had warned Christopher to stay away from the trailer across the street, where the suspect and his mother lived. She had looked up the suspect online on Georgia's sex offender registry to confirm what neighbors had told her -- that he was a convicted child molester.

According to the Georgia Bureau of Investigation sexual offender database, George Edenfield was convicted of two counts of child molestation in 1997.

"I told him, 'Christopher, they're not nice people. Stay away from them,'" Rodriguez said.

A $31,500 reward has been offered for Christopher's return. Dozens of volunteers have spent days helping search for the boy along the roadsides and in the woods surrounding the mobile home park that sits along a narrow, U-shaped road shaded by tall oaks and pines.

On Monday, the Georgia Bureau of Investigation issued a Levi's Call, the state's equivalent of an Amber Alert, for Christopher. Typically, that's only done in a known child abduction case.

"The only thing that makes any sense is he was abducted," Doering said.

Rodriguez taped a flier bearing Christopher's photo to the front of her trailer and other family members have written pleas for help in white paint across the doors and hoods of their vans and pickup trucks -- "Help Find Christopher Please."

"He's not the type to wander by himself -- this is a shy kid," Barrios said. "I won't give up until he's found."

Vigil Held For Missing Boy

Hundreds of people from the Brunswick community gathered for a vigil on Wednesday night to keep hope alive that Christopher would be found safe. People, many of whom have been volunteering their time in the past few days to help search for the boy, gathered and lit candles and prayed for the boy's safe return home.

The group supported one another as they waited on the latest word of what may have become of Christopher.

The support from the community and from people who traveled to the area after hearing about the boy's disappearance was overwhelming.

"I am a grandmother, and when I saw that grandmother on TV, my heart went out because I could not imagine had it been grandchild. My prayers have been with this family since I heard about this. It's just horrible," said vigil attendee Debbie Dixon.

"You can see all the people out here and know that no matter who is hurting in the community, everybody's going to try to support them and do everything they can to try to help that family. It's like everybody has become a family," Jennifer Thomas said at the vigil.

"I know if we lost one of our children, it would just grieve us like I know this family has grieved. We do a lot of things as a family and I hope we always will. I'm just honored to be a part of it and hope we can find him very quickly," Jim Hanna said at the vigil for Christopher.

With all the advancements being made in the search for Christopher and arrests made, the community and volunteers have continued to help in the hunt each day since the boy was reported missing.

Like the police, the volunteers said they would not give up on Christopher either.

The Glynn County Police Department asks anyone who has seen Christopher or can provide further information to call 912-554-7803 or Silent Witness at 912-264-1333.
