Whiteside County sergeant resigns after internal probe finds personal use of Flock ALPR data

Event: October 5, 2026 · First reported: October 5, 2026 · 14 sources

Whiteside County Sheriff John Booker announced on Oct. 5, 2026 that an internal investigation concluded a sergeant had used automated license plate reader data for personal reasons without a legitimate law enforcement purpose. Booker said he moved to terminate the sergeant, who resigned before the disciplinary process was completed. The case has been referred to the Illinois State Police for further review, and the sheriff's office has suspended Flock data access for all personnel. The inquiry followed reporting by a Washington Post journalist who examined a Whiteside County deputy's Flock searches.

Why this matters

The case shows that misuse of ALPR systems was identified only after outside scrutiny, raising questions about whether internal audit procedures catch improper searches on their own. The sheriff's decision to suspend agency-wide access pending policy changes offers a reference point for other departments weighing oversight of surveillance tools.
