The man burned in a propane gas explosion in Iron County yesterday has died.
86–year–old Edward Heinz of Appleton, Wisconsin died this morning at a hospital in Milwaukee.
The explosion happened shortly before 6 Central time yesterday morning on Brule Lake Road in Iron River Township.
State Police from the Iron River Post say Heinz was trying to re–light a hot water heater in his cottage.
The State Police Fire Marshal has ruled the blast an accident resulting from propane leaking into the crawlspace that contained the water heater.
But the source of the leak and the ignition source of the explosion are still unknown.
