The impact caused the Camry to spin into the eastbound lanes of the highway where it was struck by a man driving a 2016 Harley Davidson motorcycle.

The driver of the motorcycle, Brian Reynold Severin, 59, of Gaylord, Minn., died at the scene. The Toyota driver was taken to the hospital with non-life-threatening injuries.

Petzel was convicted of misdemeanor careless driving in the 2017 crash. He was not injured in either crash.
