Authorities are investigating a death that occurred during an arrest in Sidney last Sunday.

Cheyenne County Attorney Paul Schaub says two police officers had responded to a 911 call at a residence Sunday, at around 6:00 p.m., and spotted a woman running away from the home. Police went inside and confronted her husband, Dana Hlavinka, who was holding the knife, and shot him.

The Nebraska State Patrol is investigating, and a grand jury will be summoned to investigate the death, as required by Nebraska state law.

The Nebraska Attorney General’s Office has been appointed as Special Deputy Cheyenne County attorney’s, and will present the matter to a grand jury as soon as the investigation is completed.
