Michigan State Police Lt. Rick Pazder says the accident killed one person — a trucker from Ottawa, Canada — and injured an unknown number of people. He says investigators believe around 150 vehicles were involved, mostly in westbound lanes.
Some vehicles were burning in the smashup west of Exit 92, including a truck that carried fireworks. Shortly before noon, those fireworks caught fire, causing an extended display of aerial explosions.
Area hospitals reported treating 16 patients; one remained in serious condition about 1 p.m.
