We believe the high number of violations is attributable to a significant increase in enforcement standards by the MSHA inspectors that examined this mine virtually every day.

While we're very disappointed by the information we have received thus far, we remain determined to continue the search so long as there is hope, and hope remains.

The families, much like the people working in the command center, are clinging to every hope.

The foremost concern throughout this process has been that there are so many things we don't know about what went wrong. We don't want to put any more people at risk until we know answers.
