Documented Incident
Ex-Katy police officer indicted on stalking, misuse of official information over Flock searches
Event: November 2, 2024 · First reported: August 25, 2026 · 7 sources
Former Katy Police Department officer Sergio Guadalupe Rodriguez faces two third-degree felony charges in Fort Bend County — stalking and misuse of official information — after prosecutors alleged he used the department's Flock license plate reader system to track his ex-wife, Kayland Johnson, between Nov. 2, 2024, and April 2, 2025. The stalking indictment also alleges he placed a tracking device on her vehicle. Rodriguez was arrested by the Fort Bend County Sheriff's Office on May 4, bonded out on a total of $30,000, and has pleaded not guilty. Katy police said Johnson reported in October 2025 that she believed she was being tracked, prompting an internal investigation that was referred to the district attorney's office.
The case tests whether audit trails and search-privilege limits on ALPR systems catch personal misuse before or after harm occurs, a question facing every agency that has adopted the technology.
Key facts
- Charges: stalking and misuse of official information, both third-degree felonies; Rodriguez has pleaded not guilty and the allegations remain unproven in court.
- Indictments allege Flock searches occurred between Nov. 2, 2024, and April 2, 2025, plus placement of a tracking device on the complainant's vehicle.
- Bond was set at $15,000 per charge, $30,000 total; conditions bar contact with Johnson, possession of GPS trackers or AirTags, firearms, and use of law enforcement databases including Flock.
- Katy police said Rodriguez was suspended during the investigation, that the system logs a reviewable digital trail, and that periodic audits and limited search privileges are in place; officer Jim Lieberman told the Houston Chronicle the same Flock system was used in the investigation that led to the charges.
