SALT LAKE CITY -- Utah state troopers have launched an investigation into a 14-car pileup that was caused by a dust storm in central Utah.
Sunday’s accident killed two people, left three others in critical condition and injured at least 12 on Interstate 15, The Salt Lake Tribune reported Monday.
"They're trying to figure out who hit whom and how this all started," said Utah Highway Patrol Sgt. Ted Tingey.
The initial collision was likely due to low visibility from dust and ash that was kicked up from the Milford Flat fire, which burned more than 350,000 acres, said Tingey. The Milford Flat fire is the largest in Utah history, the newspaper said.
"There was poor judgment on a lot of people's parts when they came into that dust storm," he told the Tribune.
Both sides of the interstate were shut for 10 hours due to a sideways semi-truck while police and workers scrambled to clear the scene.
