It was a nightmare scenario by any reckoning: workers installing piping at a school accidentally set off a release of gas and ran to warn everyone to evacuate. Some people made it out of the building before a thunderous explosion destroyed it. Others didn’t. That’s what occurred on the morning of August 2, 2017, at Minnehaha Academy, a private school in Minneapolis, Minnesota. The blast killed two employees, custodian John Carlson and receptionist Ruth Berg, and seriously injured nine others.
Persistent rainfall has continued rain has complicated the National Transportation Safety Board (NTSB) investigation into the Feb. natural-gas related house explosion in Dallas that killed a young girl.
The incident claimed the life of the 12-year-old, injured several other people and destroyed a single family home.
