A roof fall at the Dotiki Mine in Hopkins County, Kentucky has killed at least one miner. A second miner is still missing, and the search for him continues. Dotiki Mine has a terrible safety record, Bloomberg News reports:

Alliance’s Dotiki mine ranks seventh in the U.S. by the number of “significant and substantial” violations accrued since January 2009, according to U.S. Mine Safety and Health Administration data. The operation has collected 321 citations, 35 percent more than Upper Big Branch.

… Significant and substantial, or “S&S,” violations are those that are “reasonably likely to result in a reasonably serious injury or illness under the unique circumstance contributed to by the violations,” according to MSHA.

The Charleston Gazette’s Ken Ward tallies seven disasters that killed nine miners over the past five years at Alliance mines.

According to Bloomberg, the search team can’t yet identify the body that’s been found, because the miner is trapped beneath a rock. So, two families are still waiting to hear about the fate of their loved one. Our thoughts are with them.

Updated, 4/30: The rescue team has now found the bodies of both miners.
