PORT WENTWORTH, Ga. (AP) — Firefighters finally doused the last flames Thursday of a deadly sugar refinery blast, a week after the refinery ignited.

An eighth victim badly burned in the explosion died in a hospital. At least one worker remained missing, and firefighters hoped to get inside the building to search after extinguishing the fire.

"We anticipate the search and recovery efforts to be completed, hopefully by dark today," said Port Wentworth Fire Chief Greg Long.

Sugar dust is thought to be the cause of the Feb. 7 blast.
