Update: Two employees were airlifted to Regions Hospital in St. Paul, two others were treated at St. Marys in Rochester, and two more sustained minor injuries after a paint building exploded about 10:30AM at McNeilus Truck & Manufacturing in Dodge Center, according to the Rochester Post-Bulletin.

The Dodge County sheriff said all McNeilus employees are accounted for after this morning's explosion. The identities of the victims haven't been released, but their families have been notified, said Dodge County Sheriff Scott Rose.
