The gas company may have responded to the report of a gas leak and just arrived when it occurred. The investigation will hopefully provide answers to the cause including whether the line had been deliberately severed.
If there was a gas leak reported, then what the heck was ANYONE doing in the building?
INVESTIGATIVE: Permits Found for Gas Piping and Meter Hookups at Minnehaha Academy
Hennepin County Emergency Management confirmed Wednesday morning’s explosion at Minnehaha Academy was “caused by natural gas from contracted construction being done on the building.”
KSTP’s investigative team has looked into any gas-related permits at Minnehaha Academy, the Minneapolis school that was the site of an explosion.
Permits were pulled for gas piping and meter hookup at the school on June 2.
