Marathon County sheriff’s deputies continue to investigate a crash of two semitrucks in which one of the drivers was killed. Deputies say an eastbound rig crossed a median about six a-m Thursday on the Highway 29 expressway near Edgar, west of Wausau — and it collided with an oncoming semi in the westbound lanes. The driver whose truck crossed the median died at the scene, and his name was not immediately released. Media reports say cheese boxes were scattered, which were being hauled by one of the units.
