OSI opens probe after Oswego County deputy fatally shoots man during confrontation involving metal object and injured state trooper in Constantia

Oswego County, New York – In a recent development in Oswego County, the Office of Special Investigation (OSI) under the New York Attorney General’s jurisdiction has initiated a formal probe into the death of a civilian named Miles Dignean. This investigation follows a distressing incident that occurred on March 21, 2025, involving law enforcement officers from the Oswego County Sheriff’s Office (OCSO) and the New York State Police (NYSP).

The sequence of events began on the afternoon of March 21 when both the OCSO and the NYSP were dispatched to a residence in the Town of Constantia for a welfare check. The officers were also tasked with serving an order of protection to Mr. Dignean. According to initial reports, the situation escalated into a physical confrontation during which Mr. Dignean reportedly swung a metal object, striking a NYSP trooper in the head.

In the heat of the altercation, an OCSO deputy discharged his service weapon, resulting in Mr. Dignean being critically injured. He was promptly transported to a local hospital, where he was later pronounced dead.

The OSI’s involvement stems from New York State Executive Law Section 70-b, which mandates a thorough assessment and potential investigation into any incident where the actions or omissions of a police or peace officer might have resulted in a civilian’s death. This law applies regardless of whether the officer was on duty or off, and irrespective of whether the deceased was armed or unarmed, or in custody at the time.

The opening of this investigation ensures that the incident will be examined thoroughly to determine the legality and appropriateness of the actions taken by the involved officers. It is important to note that the information currently available is preliminary and may evolve as the investigation progresses.

This incident underscores the critical role that OSI plays in maintaining oversight and accountability in interactions between law enforcement and the public. The findings of this investigation will contribute to understanding the circumstances that led to Mr. Dignean’s death and ensure that all actions taken were in accordance with the law and community standards of conduct. The community and the families involved await further details as the OSI conducts its diligent review of the events.
