Fond du Lac man who killed motorcycle driver found not guilty by reason of mental disease or defect

A Fond du Lac County man charged in a deadly motorcycle crash has been found not guilty by reason of mental disease or defect.

Online court records show Mark Snider was found not guilty in connection with the March 2025 death of 26-year-old Elijah Sowin.

Snider had been charged with second-degree reckless homicide and first-degree recklessly endangering safety.

Investigators believed Snider intentionally swerved into the path of Sowin’s motorcycle as both vehicles traveled northbound on South Main Street in Fond du Lac.

Snider was previously found incompetent to stand trial following a competency evaluation. The court has ordered his commitment, and a further proceeding is scheduled for December 9th.
