2 Kids Among 6 Dead In Montana Highway Pileup, 8 Others Hurt

The 21-vehicle pileup was the result of an isolated extreme weather event where a dust storm caused blackout conditions on Interstate 90.

Two children are among the six people who died in a Montana pileup after a Friday evening dust storm caused blackout conditions on Interstate 90, a major route in both Montana and the Western U.S.

Montana Highway Patrol Sgt. Jay Nelson said investigators so far have found no other factors that contributed to the pileup that also sent eight other injured people to hospitals.

"Everything is indicative of an isolated extreme weather event," Nelson said of the investigation, calling the crash among the worst he'd seen in 24 years with the state. "What could people do? It really was just panic."
