One of the four LaGrange firefighters badly burned in a Labor Day house fire went through his sixth surgery Wednesday, authorities said.

John Williams received burns to more than 35 percent of his body, LaGrange city spokeswoman Katie Van Schoor said in a news release.

In his latest surgery, he received a cultured epidermal autograft, which provided a permanent skin replacement, the release said. He will remain at the Augusta burn center for the next couple of weeks.
