Authorities are investigating a head-on collision in northeast Nebraska that killed one man and injured five other people.

The Pierce County Attorney says 83-year-old Ralph Schmidt of Norfolk died in the Friday evening crash in U.S. Highway 81.

The crash happened when a southbound SUV crossed the centerline and collided with Schmidt’s truck just north of the intersection of Highways 91 and 98.

Schmidt’s passenger, 70-year-old Robbie Heinemann of Norfolk, was critically injured in the crash. She was taken to Norfolk and then Sioux City for treatment.

The driver of the SUV, 60-year-old Sara Krahn, was flown to a Sioux City hospital. Her passengers, 61-year-old Isaac Krahn, 30-year-old Lisa Sawatsky and 3-year-old Jordan Sawatsky, were treated in Norfolk. All of them are from Winkler, Manitoba, Canada.
