Cheyenne County Attorney Paul Schaub says preliminary autopsy findings show that a Sidney man died Sunday evening of a self-inflicted gunshot to the head…but that it was an accidental shooting.

Authorities spent much of Monday investigating the death of 28-year old Donal Vizina, who died about 6:20 the night before.

Schaub says Vizina was at a friend’s home in Sidney when the accident occurred at 6:20 p.m. The friend told authorities that he found Vizina in a bedroom with a firearm, that at some point a shot was fired, and that he immediately called 9-1-1.
