Multiple fire departments responded about 6:45 p.m. Wednesday to 5062 Algonquin Forest off Bohleysville Road for a large fire.
The Millstadt, Columbia, Smithton, Waterloo and Hecker fire departments all responded to the blaze, fighting it for several hours.
The owners said that initial emergency dispatch reports of a propane tank explosion were not accurate. The 911 call mentioned a popping sound, but it was from tires on a camper that caught on fire. In addition to the camper, a large barn on the property was destroyed in the blaze.
Millstadt Fire Chief Kurt Pellman said the fire started due to an electrical short in the big barn. An adjacent barn was not damaged in the fire.
Greg and Karen Rakers own the property. Karen is a teacher at Gibault Catholic High School.
The Illinois Fire Marshall was investigating the cause of the fire Thursday morning.
