Five medical helicopters were also called to the incident. Seven people died in the crashes.

The crashes were caused due to excessive winds blowing dirt from farm fields across the highway, leading to zero visibility, state police said.

The state police on Tuesday initially identified one of the seven victims as Shirley Harper, 88, of Franklin, Wisconsin.

On Saturday, authorities released the identifies of five additional victims: Joseph Bates, 73, of Crystal Lake; Donna Bates, 71, of Crystal Lake; Earl LeGrand, 64, of Florissant, Missouri; Michael Zinchuk, 55, of Champaign; and Amy Zinchuk, 54, of Champaign.

Police say they are working closely with the Montgomery County Coroner’s Office to confirm the identification of the final remaining victim.
