Office of Special Investigation

The Office of Special Investigation (OSI) investigates every death in the State of New York that may have been caused by a police officer or a peace officer (peace officers includes corrections officers). If OSI concludes that an officer caused a death, OSI will either present evidence to a grand jury for consideration of criminal charges, or publish a report explaining why the evidence in the case does not warrant presentation to a grand jury. If a grand jury returns an indictment, OSI proceeds to prosecute the case.
