Well, this was posted yesterday and one user and I were discussing the ATF. If the Marshall decides it is suspicious he notifies the ATF and they come out to do the assessment. They said yesterday that it was not a gas explosion. So maybe they were using unauthorized gas, but the explosion was not due to the gas. At this point it is still questionable imo. Let me tell you that if there is info that needs to be withheld then it certainly will be.
