The Arizona Department of Public Safety continues to investigate this morning’s deadly crash on Interstate 40, near Flagstaff. Arizona Public Radio’s Aaron Granillo reports, it’s still unknown whether smoke from a nearby prescribed fire was a factor.
DPS says one person died around 3:30 this morning, when their van collided with two semi-trucks. When troopers arrived at the scene near Parks, they reported low visibility on I-40. A prescribed burn on the Kaibab National Forest sent thick smoke onto the freeway, where it settled overnight.
