A woman died near Warrens Friday morning and another was seriously injured when thick smoke from a wildfire in the Necedah National Wildlife Refuge led to multiple crashes on Highway 173 northeast of Tomah.  According to Lee Newspapers, the pileup began shortly after 8am when 61-year old Suzanne Becker’s vehicle rear-ended another driven by 34-year old Melissa Mundo about a half mile north of County Road ‘EW’.  According to the Monroe County Sheriff’s Department, Becker and Mundo were standing in the road between their vehicles when a Ford F250 pickup truck crashed into the rear of Becker’s vehicle, pushing it into the two women.  Visibility in the area was poor due to smoke from the wildfire in the refuge.  Mundo died from injuries she sustained.  Becker was initially transported by ambulance to Tomah Memorial Hospital and then med-flown by helicopter to a Marshfield hospital with potentially life threatening injuries.  The driver of the pickup, 57-year old David Peiper, received minor injuries.  Crews from the Warrens Fire Department have been battling the 25 to 30 acre wildfire in the Refuge since Thursday with help from the Department of Natural Resources and U.S. Fish and Wildlife Service.  Assistant Chief Mike Morphy said the fire started by a hawk that got tangled in power lines.  The State Patrol said Highway 173 near Warrens is closed again Saturday morning due to poor visibility.  A signed detour route is in place using Highway 80 to Highway 21 through Necedah.  The Juneau County Sheriff’s Office is warning motorists not to take shortcuts through Mather.  Do not take 9th Street ot Sprague/Mather or 8th Street or County Road ‘H’ to Mather because that’s where the fire and smoke is located.
