Sharonville Police Lt. Walter Cordes Indicted For Secret Flock Camera Searches

An Ohio police lieutenant is under indictment after prosecutors say he secretly ran his own department’s license plate cameras to track someone — 29 searches over 16 months — and Wednesday morning, he surrendered to the county jail with his lawyer at his side.

SHARONVILLE, Ohio — Walter Cordes, a veteran lieutenant with the Sharonville Police Department, was indicted Tuesday by a Hamilton County grand jury on a felony count of unauthorized use of computer, cable, or telecommunications property. The charge carries up to a year behind bars. Wednesday morning, Cordes walked into the Hamilton County Sheriff’s Office with his attorney, Stew Mathews, was booked and fingerprinted, and was released on bond. Mathews entered a written not-guilty plea on his behalf — no hearing required for a charge of this tier.

Prosecutors say the searches ran from December 2024 through April 2026 through the suburb’s Flock automated license plate reader system — the same pole-mounted cameras the department credits with helping solve violent-crime cases, hit-and-runs and catalytic-converter thefts. The target, according to the prosecutor’s office: “a person he knew.” The reason: “personal reasons unrelated to law enforcement.” The cameras never flagged a crime. The department’s own audit flagged its own lieutenant.

That’s how this one unraveled. A routine department audit surfaced the searches. Cordes sat for an interview and admitted what he’d done. The Hamilton County Sheriff’s Office took over the investigation, and this week a grand jury handed up the indictment.

Hamilton County Prosecutor Connie Pillich — who says this is the first technology-misuse prosecution of her administration — put it in four words: “He betrayed our trust.” Sharonville PD has placed Cordes on administrative leave, opened an internal investigation, and ordered department-wide retraining on database use. The police union is standing behind his due process. And the cameras themselves aren’t going anywhere: the department adopted the Flock system in 2023 and credits it with helping solve real cases, and its answer to the audit wasn’t a camera teardown — it was retraining for everyone who touches the database. All of them stay up.

The pattern isn’t new. A Florida deputy ran one plate 717 times watching his estranged wife. Analysts in Texas and Georgia logged more than 2,000 lookups each. What makes Sharonville different is that nobody outside had to catch it — the audit did, and the department turned its own lieutenant over for prosecution.

Which leaves the question every outlet is reporting around: who was Walter Cordes tracking? Officials will only say it was a person he knew, for personal reasons. There’s a name in those 29 searches. Not one agency will say it.

Cordes is presumed innocent until a court says otherwise. But the case already answers the question every department running these cameras should be asking: who’s watching the watchers? In Sharonville, this time, the answer was the system itself.
