SUPERIOR, Neb. -- Authorities have identified two victims killed in a Thursday shooting at an elevator in Superior.

The Nebraska State Patrol says 53-year-old Darin Koepke, of Hadar, and 60-year-old Sandra Nelson, of Formoso, Kan., died of injuries sustained in the shooting at Agrex Inc.

Nelson was pronounced deceased at the scene of the incident in Superior. Koepke was flown to Bryan Health West Campus in Lincoln where he was later pronounced deceased.

A third victim was treated for non-life-threatening injuries at the hospital in Superior and released Thursday afternoon. After the shooting began, an Agrex employee retrieved a shotgun from an office and returning fire, striking the suspect.

The suspect was identified as Max Hoskinson, 61, of Superior. He allegedly returned to Agrex and opened fire after being terminated from his job there earlier in the day. Hoskinson was pronounced dead as a result of his injuries at the hospital in Superior.

In consultation with the Nebraska Attorney General’s Office and the Nuckolls County Attorney’s Office, no charges are anticipated in relation to the employee who returned fire.

The names of other individuals involved in this incident are being withheld at this time due to the ongoing nature of the investigation. Additional information will be released when possible.
