JOHNSTON &#8212 An Iowa soldier was killed Friday during convoy operations in Afghanistan, the Iowa National Guard said.

Sgt. 1st Class Scott Carney, of Ankeny, was a passenger in a Humvee that rolled over near Herat, Afghanistan, according to officials. He was assigned to the National Guard’s 2nd Brigade Combat Team, 34th Infantry Division, in Boone.

His unit arrived in Afghanistan in May and provided advanced combat training to the Afghan National Army and police.

Sgt. 1st Class Daniel E. Miller, 43, of Rossford, Ohio, was also killed. The accident is currently under investigation.

Carney, 37, who graduated from Sheridan High in Thornville, Ohio and attended Upper Iowa University, had served in the military since 1989.

He is survived by his wife, Jeni, and twin sons, Jacob and Justin.

“Scott died doing what he loved, serving his country and protecting the freedom that we enjoy and providing the people of Afghanistan with the opportunity for freedom,” his family said in a statement.

Funeral arrangements are pending at Westover Funeral Home in Des Moines.
