SIDNEY, Neb. - Authorities are investigating a fatal shooting that occurred Tuesday morning at a rural residence south of Sidney.

According to Cheyenne County Attorney Paul Schaub, the Cheyenne County Sheriff’s Office responded to a shots-fired call at a home on County Road 109 in Cheyenne County at 10:06 a.m. Emergency communications advised authorities a father had been shot by his son during an incident. A third individual, the mother, was present at the time of the shooting and attempted to administer CPR to the victim before emergency responders arrived. 

Emergency medical personnel worked on the victim for approximately 50 minutes but were unable to revive him.

Schaub says no individuals involved in the incident are currently in custody. Preliminary investigation findings suggest the shooting was conducted in self-defense.

The investigation is ongoing and an autopsy is scheduled to take place Wednesday.
