Nassau County District Attorney

What Nassau County District Attorney does

The Nassau County District Attorney's Office is a county-level government law enforcement agency headquartered at 262 Old Country Road, Mineola, New York. It is the statutorily designated prosecutor for violations of state and local criminal statutes occurring within Nassau County — the most populous suburban county in New York State, with over 1.3 million residents. Led by District Attorney Madeline Singas, the office operates across a Litigation Division, Investigations Division (with six bureaus and five units), and a Special Proceedings Division, organizing prosecutorial work into specialized units covering Major Crimes/Homicide, Special Victims, Vehicular Crimes, Narcotics/Firearms/Gangs, Organized Crime/Rackets, and Major Financial Frauds.

The office's citizen-facing technology is built on the CivicPlus government website platform (nassauda.org), which integrates content management, FOIL request processing, press release distribution, event management, and a structured Tipline Complaint System with dedicated phone extensions for specific crime categories. Key services include an online File-a-Complaint portal, a Defense Discovery portal for legal professionals, annual reports, and the Heroin Prevention Task Force — a multi-agency coalition co-chaired with the Nassau County Executive and including partners such as NCPD, Probation, OASAS, Northwell Health, Adelphi School of Social Work, and the Nassau Region PTA. The "Not My Child" heroin-awareness presentation program extends community-facing services into schools and parent groups.

The office does not operate a commercial business model. Core prosecution, victim services, and community safety services are taxpayer-funded through Nassau County government budgets and provided at no charge. The only fee-bearing product is FOIL record duplication at $0.25 per page (or actual reproduction cost for non-standard formats), mandated by New York State Public Officers Law § 87(1)(c), with no fee-waiver provisions. The customer base is horizontal: all Nassau County residents, businesses, and visitors who require access to criminal justice, victim support, or public-safety resources. Revenue/signals are therefore analogous to a government operating budget rather than commercial ARR; no revenue figures are publicly disclosed.

Expansion highlights5 records

Direct peers

• Suffolk County District Attorney: The Suffolk County DA's Office is the most direct peer: same state, adjacent Long Island county, comparable suburban jurisdiction and population scale. Both offices prosecute state/local criminal violations, run similar specialty bureaus, and operate heroin/opioid task forces, making them natural peers for benchmarking and resource comparison.
• Westchester County District Attorney: A New York State suburban county DA's office with similar population profile and prosecutorial scope. Comparable organizational structure with specialty bureaus (Major Crimes, Special Victims, Narcotics) and serves as a peer for operational benchmarking within the NY suburban county DA cohort.
• New York County District Attorney (Manhattan DA): The Manhattan DA's Office is a same-state, same-function peer operating a much larger jurisdiction. It runs comparable specialty divisions (Homicide, Cyber, Financial Frauds, Special Victims), provides prosecution services for state/local statutes, and serves as a leading reference point for prosecutorial practice and policy in NY.
• Kings County District Attorney (Brooklyn DA): The Kings County DA prosecutes criminal violations in Brooklyn and operates with comparable specialized bureau structures (Homicide, Rackets, Special Victims). Same state and function; comparable tier of prosecutorial capability and complexity.
• Queens County District Attorney: The Queens County DA is a same-state, same-function peer operating one of the most diverse and high-volume county jurisdictions in the U.S. Directly comparable in mandate (prosecution of state/local criminal statutes) and structure (specialty bureaus, community outreach).
• Bronx County District Attorney: The Bronx County DA is a same-state, same-function peer with comparable specialized bureau structures (Homicide, Special Victims, Narcotics). Serves as a peer for operational benchmarking and resource comparison within the NYC county DA cohort.

Broad incumbents

• New York State Office of the Attorney General: The NY State AG is a broader-incumbent public prosecutor operating statewide with overlapping functions (financial fraud, organized crime, public integrity prosecutions). Comparable in mission (criminal prosecution on behalf of the public) but at a larger, statewide scale rather than county-level.
• United States Attorney's Office - Eastern District of New York: EDNY is the federal prosecution counterpart operating in the same geographic region as Nassau County, handling federal criminal violations including organized crime, narcotics trafficking, and financial fraud. A broader-incumbent peer in prosecution function, with overlapping subject-matter jurisdictions.
• Los Angeles County District Attorney: The LA County DA is the largest county prosecutor in the U.S., serving ~10M residents. A broader-incumbent peer in function (county-level criminal prosecution) and structure (specialty bureaus, community outreach) though at significantly larger scale; useful for understanding scale economics and best-practice transferability.
• Cook County State's Attorney: The Cook County State's Attorney is the chief prosecutor for Chicago and Cook County, Illinois, operating one of the largest county prosecution offices in the country. A broader-incumbent peer in function and scale tier, providing cross-jurisdictional benchmarking for large urban DA operations.
