BRUNSWICK, Ga. -- Glynn County police, the Georgia State Patrol, the Georgia Bureau of Investigation and other agencies have joined the search for a 6-year-old boy who did not return home Thursday night.

According to police, Christopher Michael Barrios Jr. was last seen on a swingset in the Canal Mobile Home Park on Horseshoe Lane around 6:15 p.m. When he was not home just after 8 p.m., police were called.

He was last seen wearing a blue or green long-sleeve shirt with a white T-shirt underneath and long black pants. He was wearing white tennis shoes with a blue stripe on the side with a Velcro closure on top.

He is a Hispanic and black male with short black hair and brown eyes. He is between 3 feet 6 inches and 4 feet tall and weighs between 60 and 70 pounds.

"We did a search all night long," Glynn County Police Chief Matthew Doering said. "At daylight this morning we started another search of the area ... but this morning we included two helicopters."

Mounted patrols and ATVs assisted dozens of people are searching on foot. Doering said one mile of woods near Canal Road near the Federal Law Enforcement Training Academy were searched by late Friday.

A toy Christopher was carrying Thursday night was found, but no sign of the boy.

Barrios' family told Channel 4 Dan Leveton they were grateful for the intensive search efforts.

"I love him to death -- I want him to come home," his grandmother, Ellen Sue Rodriguez, said on Friday.

"We don't have anything to go on about whether there was an actual abduction, whether someone within the neighborhood or area took him out in the woods nearby," Doering said. "e simply don't have anything: no suspicious vehicles reported to us, no suspicious people reported to us."

Doering has requested that the state issue a Levi's Call -- which is Georgia's equivalent of an Amber Alert -- but there was no confirmation that it was issued.

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