When he hit the road, Hayes was running away from trouble back home. He faces burglary and theft charges in his home county, stemming from an arrest late last year, according to Grayson County court records.
He was planning to be at the local judicial center on Jan. 5 to find out if a grand jury had indicted him on the charges, his mother said. His case did not come up, but by that time the teens were gone.
