A 9-year-old boy has been found safe after going missing from the YMCA's Camp Greenville Thursday evening in mountainous territory near the North Carolina border.

NEW:How a 9-year-old boy survived a night alone after going missing from Camp Greenville

Matthew Yarborough was located around 8 a.m. about two miles from his last known location, said Lt. Ryan Flood, a spokesman for the Greenville County Sheriff's Office.

Multiple agencies from North and South Carolina were involved in the search as it continued Friday for the boy, originally identified by the Sheriff's Office as a 10-year-old with autism.

Cedar Mountain Fire and Rescue and the Transylvania County Sheriff's Office were also among agencies involved, according to Jimmy Jones, spokesman for Cedar Mountain Fire and Rescue.

A helicopter and drones equipped with infrared cameras and K-9s were employed by the search team before someone at the nearby Green River Preserve summer camp found the child.

The call to report the boy missing was received at 5:48 p.m., Flood said, and about 130 people were involved in the search last night. More than 30 people searched through the night, and 23 searched this morning.

At about 1,400 acres, Camp Greenville is the fifth-largest YMCA camp in the nation, according to the YMCA of Greenville. The camp is more than 100 years old, and it stands at an elevation of about 3,200 feet off U.S. 276 about 17 miles southeast of Brevard, North Carolina, and 38 miles north of Greenville.

In its many years of existence, the camp has never had a missing child scenario similar to Thursday night's incident, said Amanda Long, a spokeswoman for the YMCA.

Counselors go through 14 days of "intense training" prior to campers arriving, Long said. In Matthew's cabin there were 10 campers and two adults, she said.

A number of programs and events are held there. About 12,000 children attended programs there in 2015, when more than $5 million was raised for improvements at the camp.
