Darrious Jackson, 19, of North Augusta, and Brandon Helm, 17, of Hephzibah, each face charges of burglary and contributing to the delinquency of a minor, according to Richmond County Sheriffs Investigator Alton Creech.
An unnamed 15-year-old juvenile is also charged with burglary, he said.
A fourth suspect, Darian Postell, 18, of Hephzibah, surrendered this afternoon, authorities said.
The suspects are believed to have forced their way into storage buildings at the South Augusta Flea Market property on Doug Barnard Parkway.
They cut the locks and then took a large amount of Air Jordan tennis shoes and miscellaneous clothing, Investigator Creech said.
The suspects allegedly left the property then returned to steal more items later that day, police said.
