Bruce Spencer, 59, of Ellsworth died from burns sustained Tuesday in a propane explosion inside a bus converted into a motorhome.
According to the Office of State Fire Marshal, the explosion occurred in a cabinet under a propane stove. Investigators believe the blast ignited an electric refrigerator compressor motor. The gas leaked from two 25-pound propane tanks stored in a rear exterior compartment. The source of the leak has not been determined. The investigation is ongoing.
