NORFOLK, Neb. (AP) — Authorities say a man suspected of shooting another man before a standoff with police officers has been found dead inside a Norfolk house.

Norfolk police say the body of 47-year-old Cory Dittman was found by officers who entered the home late Sunday night or early Monday morning. Police say he died of a self-inflicted gunshot wound.

Police say the standoff began Sunday morning after Dittman shot 63-year-old Leone Bussey, who has undergone surgery.

Negotiators were unsuccessful in attempts to teach Dittman on a cellphone or landline.

Police say Dittman opened fire from when officers fired tear gas or another chemical agent into the house in an effort to make him surrender. No injuries have been reported.

State prison records say Dittman had served time for arson and other crimes.
