MESA COUNTY, Colo. — A firefighter has died from injuries he sustained while battling a wildfire near the Utah-Colorado border last month, making four deaths in total.
Nathan Matthews, 43, passed away on Friday, according to the U.S. Department of the Interior. He was injured while responding to the Knowles Fire on June 27.
Matthews, from Lincoln, Nebraska, was part of the Rifle Helitack crew that was in a "burnover" incident, where a fire overtakes personnel, leaving them unable to escape.
Emily Barker of Michigan, Nick Hutcherson of Arizona and Sydney Watson of Alabama were killed in the fire.
