In brief

The Union County Sheriff's Office logged 48 internal affairs investigations in 2025 and 34 officers named in those cases. Its rate of 141.2 per 100 officers matched the county median of 141.2 and ran above the 115.2 median for sheriff agencies statewide, which can reflect more misconduct or a stronger habit of documenting complaints. Twenty-one of the 48 investigations detailed for 2025 reported sustained complaints. Demeanor accounted for 16 of the cases, ahead of Insubordination/Disobeying An Order and Neglect of Duty.

Five major discipline records appear across the 2020-2025 releases, from 2022, 2023 and 2025, including two terminations. The office received a C on the report card, the 40th percentile among 21 peers across all sheriff agencies, a high-confidence grade.

Staffing

Staffing data not available. The FBI's national staffing census (LEE) does not separately track county corrections facilities, sheriff's offices, or other county agencies in New Jersey -- only a single statewide Department of Corrections figure exists in that data. See the methodology for what FBI staffing data does and does not cover.

Military surplus equipment (1033 program)

No 1033 transfers recorded. No surplus-equipment transfers appear for this agency under a high-confidence name match in the Defense Logistics Agency's file as of 2026-06-30. That can mean the agency received nothing through the program, or that a recipient name in the federal file did not confidently match this department. See the methodology for how the match is made, or the statewide 1033 overview for how the program spreads across New Jersey.

What this grade can and can't tell you

  • The underlying data is self-reported by agencies, one yearly snapshot at a time.
  • Allegations are not findings; many complaints end unfounded, exonerated, or not sustained.
  • There is no arrest or call-volume denominator in this data, so nothing here is a per-capita misconduct rate. A genuinely independent staffing-based rate, sourced from the FBI rather than this grade's own data, appears above when available. It is a different measurement, not a more accurate version of the grade.
  • A higher internal affairs volume is ambiguous: it can indicate more misconduct, or a more robust oversight and reporting culture. The grade weighs it anyway, because volume is what the record offers; that choice is published, not hidden.
  • The grade is one lens. The records it reads are on this page above.

Fatal encounters recorded involving this agency

From the independent Fatal Encounters dataset, 2000-2021

In brief (written by this site from the records below)

Two records in the Fatal Encounters dataset name the Union County Sheriff's Office, one from 2004 and one from 2005. The dataset's own as-recorded force label is Gunshot in both. Fatal Encounters was an independent, crowdsourced journalism project that documented deaths occurring during police encounters of any kind, including vehicle pursuits, medical emergencies, and suicides in police presence. A record is not a finding of fault, and it does not say police caused the death. The project stopped collecting in December 2021, so the dataset is frozen at that point.

Fatal Encounters is an independent, crowdsourced dataset that documented deaths during police encounters nationwide from 2000 until its collection ended in December 2021.[2] It records all deaths that occurred during a police encounter of any kind: vehicle pursuits, suicides in police presence, and medical emergencies are included alongside uses of force. A record appears here because Union County Sheriff's Officeis named in the record's as-reported agency field. A listing is not a misconduct finding, and it is not connected to the Attorney General discipline records above. See the methodology. Each record links to its own page with the full as-reported details.

What this section can and can't tell you

  • A request is not a finding. Every entry records what a member of the public asked for. None of it establishes that an agency did anything, and none of it is an allegation this site is making.
  • Statuses come from the requester, not the agency. On OPRAmachine the person who filed the request classifies the response they got, so “successful” means they said they got what they asked for. It is not the agency's word and not an adjudication.
  • Request volume is not a measure of misconduct. A long list usually reflects public interest, local journalism, or one determined requester. A short list usually means few people have asked.
  • This covers OPRAmachine only. Most OPRA requests in New Jersey are filed directly with agencies and never appear here, so this is a floor, not a total.
  • It is frozen at 12 July 2026. The figures come from a snapshot of OPRAmachine taken on that date and nothing refreshes them, so anything filed since is missing. Treat every number here as a lower bound that is only getting further out of date.

The match between this OPRAmachine body and this department is this site's inference, not a certified mapping. If it is wrong, we will remove it: corrections.
