Curt and Alex were working atop the silo that morning when both passed out from the fumes. Alex’s brother called 911 and his uncle Steve, who went to the top of the silo to help his brother and nephew, before being overcome by the gas himself.

The MIllerville Fire Department, of which both Curt and Steve were volunteer members, arrived at the scene and pulled all three from the silo. Steve was pronounced dead at the scene. Alex was taken by helicopter to Minneapolis, while his dad was flown to St. Cloud Hospital, were he later died.
