Governor Tim Walz says all three crew members in a Minnesota Army National Guard helicopter crash are dead.  The UH-60 Black Hawk went down south of St. Cloud.  Governor Tim Walz says they are ready to help the families involved.

Officials say they lost contact with the aircraft earlier today while it was out on a maintenance test flight.  The Saint Paul Fire Department says they responded to the scene after the helicopter sent a "mayday" call.

The MN National Guard twitter feed shared, "Our Minnesota National Guard family is devastated by the deaths of these soldiers," said Maj. Gen. Jon Jensen, the Adjutant General of the Minnesota National Guard. "Our priority right now is ensuring that our families are taken care of."

The Minnesota National Guard says the names of the deceased will be withheld pending next of kin notification. An investigation is currently being conducted.
