Katy Cop Searched His Ex-Wife’s Plate 2,386 Times – Then Put A Tracker On Her Car
Sergio Guadalupe Rodriguez spent about ten years as a Katy police officer with a login to one of the most powerful surveillance grids in the Houston area. Court records say he pointed it at one person: his ex-wife. By the internal-affairs count, he ran her plate through the city’s camera network 2,386 times in eleven months — and prosecutors say even that wasn’t enough: the indictment alleges he attached a physical tracking device to her car.
A Fort Bend County grand jury indicted Rodriguez, 42, on two third-degree felonies: stalking and misuse of official information. Each carries up to ten years in prison and a $10,000 fine. His ex-wife, identified in KPRC 2’s reporting as Kayland Johnson, filed a complaint in October 2025 alleging he “was somehow tracking her whereabouts.” Katy PD suspended him immediately, then noted the irony itself: “the Flock camera system that was abused is the same system that was used to bring formal charges against the officer.”
What the indictments say
The alleged conduct ran from November 2, 2024 to April 2, 2025, per Covering Katy’s review of the indictments. The misuse count alleges he used law-enforcement access for a personal purpose rather than police work — “tracking the location” of his ex-wife. The stalking count cites repeated use of the plate-reader system to follow her movements, plus “a tracking device on the complainant’s vehicle,” leaving her — in the indictment’s words — “harassed, annoyed, alarmed, abused, tormented, embarrassed, or offended.”
The 2,386 figure comes from internal-affairs records obtained by KHOU. A local law enforcement official urged caution on the math: “We have over 600 cameras in FBC. If I run a search for the whole area, it’ll show I ran 600 searches.” Even at the low end, no one has explained why an officer’s ex-wife kept appearing in his queries.
A grid built for total coverage
Katy owns roughly 40 Flock cameras, but its subscription reaches far beyond them: statewide and nationwide plate lookups, private-property cameras, and feeds shared by other agencies. Flock logs what it calls a “permanent, unalterable digital audit trail” of who searched what, when, and why. That trail built the case against Rodriguez once a complaint forced anyone to look.
The department says it now runs monthly random audits of officers and quarterly audits of everyone with search access, and that only investigative-role officers can query the system. Controls added after the fact. Nothing stopped the searches while they were happening.
Arrest, bond, and the department’s answer
The grand jury indicted Rodriguez on April 6; he was arrested May 4 after warrants were issued and booked into the Fort Bend County Jail on $30,000 bond. His bond conditions read like a list of the accusations: no Flock databases, no tracking devices — GPS units, AirTags, location-tracking apps — no firearms, and no contact within 1,000 feet of his ex-wife, with a May 21 carve-out for custody exchanges.
He has pleaded not guilty and waived formal arraignment; court records identify Charles Zavala as his attorney. Both cases are pending in the 268th Judicial District Court. Katy PD says he has been terminated, declining to give an exact timeline.
What happens next
Rodriguez is due back in court Sept. 2. Houston PD has since opened its own audit of officers’ Flock use, placing some accounts on hold. Union president Douglas Griffith said Flock’s algorithm flagged the officers. Asked whether any involved stalking, he answered: “I wouldn’t doubt that we’d have a case or two.”
Every charge is an allegation right now. Rodriguez is presumed innocent unless and until proven guilty — the same standard his badge was supposed to represent. This post will be updated as the court record develops.
The audit trail logged all 2,386 searches as they happened. The question is why it took an ex-wife’s complaint — not the system — to make anyone look.
