3 firefighters killed, 2 injured in Colorado-Utah wildfire burnover

Three firefighters were killed and two sustained burn injuries when they were overcome by flames from fast-moving wildfires in hot, windy conditions near the Colorado-Utah border.

The firefighters deployed emergency shelters for themselves during the so-called burnover — which occurs when a fire spreads and closes off all escape routes.

They worked for the U.S. Wildland Fire Service and U.S. Forest Service and were part of an interagency response to the Knowles and Gore fires, which merged with other fires.
