PORT WENTWORTH, Ga. AP – Firefighters hoped a dose of sand would finally extinguish smoldering fires that have stalled the search for two workers still missing on Monday, four days after a deadly explosion at a sugar refinery.

Search crews found the body of one of three missing workers on Sunday before the search was called of at sunset, Insurance and Safety Fire Commissioner John Oxendine said. That pushed the death toll to six, with dozens more injured.
