This is a tragedy of epic proportion. I have no idea of the grief the family is going though, but my heart hurts for them.

The above ADN story leaves me wondering about the investigation: "Investigators also ruled out an electrical cause for the fire, Tyler said. There were no electrical devices or appliances near the fire's origin. Outlets were checked but there were no signs the fire started there"

From yesterday's story: "Butte mobile home had electrical issues before fire that killed 5 girls, grandmother says" Enstar spokesperson Lindsay Hobson reported: "I know that gas was not a factor in this fire," Hobson said. "I know that our readings showed zero percent at the foundation. And there was no gas to that meter because, as you say, it had been shut off the day before."

If it wasn't electrical and there's no natural gas, what are the investigators not telling us was the fuel/ignition source of the fire? It could be as simple as matches, propane or even a sterno-style stove?
