Arizona Dust Storm Causes Deadly Pile-Up
A sudden dust storm south of Phoenix blinded drivers Tuesday morning on Interstate 10, setting off a chain of collisions that killed three people, police said.
I-10 eastbound in Casa Grande was expected to be closed all day. The westbound highway was closed off and on because of poor visibility.
Two of the dead were local teenagers, Mark Eide, 17, and his sister, Katie, 14. Police said their SUV burst into flames after being struck by a tractor-trailer.
Edgar Ivan Medina-Vargas of Iowa City was also killed. His pickup truck was hit by a truck driven by his father, who was following him, and then struck by two semis.
Harold Sanders, a spokesman for the Arizona Department of Public Safety, said drivers who see dust storms ahead of them should immediately get off the road.
