Wind-driven wildfires sweeping through parts of Nebraska killed a retired fire chief and injured at least 15 firefighters, authorities said Sunday.

The man who died Friday night was a retired Cambridge fire chief who was working with firefighters as a spotter in Red Willow County in the southwestern corner of the state. That fire had burned more than 78 square miles (202 square kilometers) in Red Willow, Furnas and Frontier counties by Sunday afternoon.

The Nebraska Emergency Management Agency said firefighters were still working to contain that large fire Sunday, and officials didn’t have an estimate of how much of it had been contained.

Alyssa Sanders, with NEMA, said 66-year-old John P. Trumble, of Arapahoe, was overcome by smoke and fire after his vehicle left the road Friday because of poor visibility from smoke and dust. His body was found early Saturday.

At least 15 firefighters have been injured battling the blazes, including five who were hurt in the fire that killed Trumble, but a spokeswoman said the state agency didn’t have details about their injuries.

Blazes have been reported in 14 counties in around the state since Friday, including Perkins, Dundy, Burt, Butler, Scotts Bluff, Cheyenne, Duele, Blaine, Cherry, Brown and Thomas counties. The state agency said those other fires had either been extinguished or mostly contained by Sunday afternoon.
