MORRISON, Illinois – A newly obtained court filing identifies Alexandria Deyo as the former Whiteside County sheriff’s sergeant who resigned after an internal investigation found she accessed the county’s automated license‑plate reader system, known as Flock, for personal reasons.
Petition for no‑contact order
The filing shows Deyo is the respondent in a petition for a stalking no‑contact order filed in the Bureau County Circuit Court. The petitioner, whose name is not disclosed, alleges Deyo searched a license plate 108 times between May 6 and June 14, 2025, using the Flock camera databases. Sheriff John Booker later confirmed the dates, times and number of searches.
How the alleged misuse was discovered
According to the petition, the petitioner was tipped off on Oct. 11, 2026, that Deyo was using the Flock system to search for them. The following day, an unfamiliar TikTok account began following the petitioner. After accepting the request, the petitioner examined the account and found videos featuring Deyo, recognizing her as a deputy despite never having met her.
The petitioner contacted Sheriff Booker, who confirmed the petitioner had indeed been searched for in the Flock system. Concerned for personal safety, the petitioner asked the court to prohibit Deyo from making any contact and to require her to stay at least 300 feet away.
Sheriff’s office response
In September, Sheriff Booker told KWQC that the department was investigating possible misuse of Flock data. At that time, a deputy had been placed on administrative leave, but the sheriff declined to identify the employee. In October, the internal investigation confirmed that a sergeant had accessed license‑plate reader data for personal reasons. Booker said he intended to fire the sergeant, but Deyo resigned before the termination could be completed.
The case has been referred to the Illinois State Police for further review, though Deyo has not been charged with a crime. In response to the incident, Booker suspended Flock data access for all sheriff’s office personnel and announced plans to tighten internal auditing procedures.
Understanding the Flock system
The Whiteside County Sheriff’s Office does not own or operate the Flock cameras; however, its personnel have access to data collected through the broader network. Flock’s automated license‑plate reader system captures images of passing vehicles and records information such as license plates, vehicle characteristics, locations and timestamps. Participating law‑enforcement agencies can search the data to assist investigations, but strict controls are essential to protect privacy and maintain public trust.
Implications for the community
This incident underscores the importance of robust oversight of law‑enforcement technology. While the sheriff’s office acted quickly to suspend access and improve auditing, residents are reminded that safeguards must remain vigilant to prevent misuse of powerful surveillance tools. The ongoing state‑police review will determine whether additional measures or disciplinary actions are warranted.
