The public is invited to a celebration of life Thursday night at Decorah High School for two students killed in a weekend crash. The Iowa State Patrol said a car driven by 18-year-old Dalton Hemesath went into the ditch and rolled multiple times Friday in Winneshiek County. All five occupants were thrown from the vehicle. State troopers say Hemesath and 18-year-old Karter Einck died at the scene. Reports show 17-year-olds Emmit Stemper and Brenden Hunter, as well as 18-year-old David Kreitzer were airlifted to a hospital with serious injuries.
