Mine owner Massey Energy kept two sets of records that chronicled safety problems. One internal set of production reports detailed those problems and how they delayed coal production. But the other records, which are reviewed by federal mine safety inspectors and required by federal law, failed to mention the same safety hazards.

Read more then tell DOJ to hold Massey Energy accountable for the deaths of 29 workers.
