An ongoing investigation continues into a structure fire in the Wheeler area Tuesday night that required fire crews from three counties to help fight the blaze. Union Volunteer Fire Department Chief Tim Beach tells the Region News Team a Portage Fire Department K-9 hit on three different spots at the log cabin style home on County Road 625 West that was being rebuilt after a fire there in 2011. Beach says the ATF and State Fire Marshal gathered samples at the three spots for further testing. No injuries were reported and Beach says the house is a total loss. Crews arrived at the scene shortly after 10pm and left the scene just before 3am.
