State police say a 193-vehicle pileup that closed a stretch of I-94 in Michigan for two days started in the eastbound lanes and likely spread to westbound lanes because drivers became distracted by the crashes. Investigators have no evidence that cars or trucks crossed the median in eastern Kalamazoo County. A trucker killed Friday was not at the front or the back of the crashes. It could take weeks to determine what happened, but the work to figure it all out has begun with the help of GPS data. State police are treating crashes on each side of I-94 as separate crash scenes. The pileup was between mile markers 88 and 92, near Galesburg.
