Holiday Hills police chief and part‑time officer in Prairie Grove was arrested on June 18, 2026 and charged with two counts of official misconduct, a Class 3 felony. Prosecutors say he leveraged the village’s Flock license‑plate reader and the Illinois State Police LEADS database to follow six personal contacts, including three former romantic partners, and queried an ex‑boyfriend’s plate 140 times, half while off duty.

The Holiday Hills case fits a growing docket of chief‑level abuse. The Institute for Justice has documented at least 18 nationwide incidents where senior officers used Flock LPR to monitor spouses, rivals or former lovers, including a Georgia chief arrested after a GBI audit and an Idaho sheriff who ran his wife’s plate 700 times. Advocates argue these patterns expose a systemic gap in oversight.

Civil liberties groups including the ACLU, EFF and Institute for Justice press courts to require a warrant before any non‑emergency LPR query. Precedent from United States v. Jones and Carpenter v. United States already mandates warrants for GPS and cell‑site data, and judges have begun extending that logic to stored license‑plate reads. The documented chief abuses underscore why a warrant rule is now essential.
