Troopers from the Wisconsin State Patrol were working an active crash scene at milepost 115 on Interstate 94. While investigating and attempting to clear the original crash, passing motorists were slowing for the crash scene when a second crash occurred.
Preliminary investigation shows a GMC Sierra was westbound on Interstate 94 and failed to sufficiently slow down and rear-ended a slower-moving vehicle. The GMC Sierra left the roadway and struck a Tractor Trailer unit parked on the shoulder of the roadway. Troopers on the scene attempted life-saving efforts, however, the 79 year old Robert Leonhardt, driver of the GMC Sierra later succumbed to his injuries.
