The Madison County Sheriff’s Office is cautioning people to be alert for debris from yesterday’s helicopter crash of a UH-60 Black Hawk helicopter.

The helicopter crashed on a Madison County highway, killing two Tennessee National Guardsmen aboard the aircraft.

In a series of tweets, the sheriff’s office warned residents that debris could be scattered across areas near the crash site.
