9 others injured

Nine other people – none of them students – were brought to the Hennepin County Medical Center following the explosion. 

As of 6 a.m. Thursday, the hospital said one person was still in critical condition. Two others were listed as satisfactory (that's one fewer than Wednesday afternoon.)

Minnehaha Academy said the explosion injured "administrative staff," but didn't elaborate on exactly who was among the injured. WCCO is reporting the victim listed in critical condition is the school's assistant soccer coach Bryan Duffey.

What caused the explosion?

Hennepin County Emergency Management confirmed the explosion was the result of a natural gas leak caused by construction that was being done on the building. 

Master Mechanical, the company doing work on the building, released a statement to KSTP

"Our thoughts and prayers are with everyone involved in the incident. We are monitoring the situation and at this time we are referring all questions about the event to the Minneapolis Fire Department out of respect for their investigation."
