Authorities have confirmed that a man who shot a police chief during a standoff in Orange County fatally shot himself.

An official confirmed that autopsy results showed 28-year-old Anthony Bostick died of a single, self-inflicted gunshot wound to the head after shooting Police Chief Arnold Amthor in Maybrook.

Authorities say shots were exchanged when Amthor was trying to remove Bostick from his apartment on Abby Avenue Tuesday during a domestic incident with his girlfriend that started the night before. Amthor was shot in the shoulder and is now recovering at home.

Officials say Bostick barricaded himself inside his third-floor apartment, where he was later found dead.

Police have not released any details about the dispute that brought them there, but neighbors say the couple just moved in two weeks ago.

The incident remains under investigation, but so far authorities say Chief Amthor's actions appear to be justified.
