Sandra Sandy Sue Nelson, 60, was killed at the Agrex Inc. grain elevator in Superior, Nebraska, on October 21, 2021. A longtime grain merchandiser and active community member who graduated Superior High School in 1979 and attended Cloud County Community College, she lived in nearby Formoso, Kansas, with her husband.

Nelson was fatally wounded at the scene. Darin L. Koepke, 53, of Hadar was critically injured and later died at a Lincoln hospital; a third victim suffered non-life-threatening injuries and was treated and released. An Agrex employee retrieved a shotgun from an office and shot Hoskinson; he was taken to a Superior hospital and pronounced dead. The Nebraska State Patrol, after consulting the Nuckolls County Attorney’s Office and the Nebraska Attorney General’s Office, announced no charges would be filed against the employee who shot Hoskinson, concluding the employee acted to protect himself and others.

Anyone who knew Sandy Nelson or was at the Agrex elevator that day and can share memories or information is asked to come forward.
