A motorist who had seen a news report about Stephen Kenneth Colbert of Wylie, Texas, spotted the boy near the central Indiana town of Mooresville on Saturday morning, took him to a nearby restaurant and called police, Indianapolis Metropolitan Police Officer Kendale Adams said.
Colbert was reunited with his mother, Kristen Colbert, at a Mooresville hospital later Saturday, Adams told The Indianapolis Star. The boy was taken to the hospital as a precaution.
However, investigators don't know how the boy traveled to Mooresville, Adams said.
"We did talk to him. He really couldn't provide us with anything concrete on how he ended up down there," Adams said.
Colbert told police that he woke up outside at 7:30 a.m. Saturday near a building that he couldn't describe very well and police couldn't locate. There were no visible marks on his body and no indications that he had been assaulted or abducted, Adams said.
Colbert was attending the Music for All National Festival with other students from Wylie High School. Colbert had last been seen at a concert on campus about 7 p.m. Thursday. The festival features live performances from young musicians in concert bands, orchestras and percussion ensembles.
Colbert was reported missing when he didn't show up for a head count at the motel where the students were staying, according to WFAA-TV in Dallas.
Kristen Colbert and the Wylie principal, Virdie Montgomery, flew to Indianapolis on Friday to join the search for the boy and to post fliers around the Butler campus.
David Vinson, the superintendent with Wylie Independent School District, expressed relief that the boy had been found.
"There are still questions, but the important thing is he is safe. I know that the entire Wylie community, and many others, were praying for him and his family, and this is an answered prayer," Vinson said.
District spokesman Ian Halperin said the students were traveling with several chaperones.
