Katy, Texas police officer Sergio Rodriguez indicted, fired for using Flock cameras to stalk ex-wife 2,386 times

Fort Bend County prosecutors indicted Katy, Texas police officer Sergio Rodriguez on April 6, 2026, on two third-degree felony charges -- stalking and misuse of official information -- and the Katy Police Department fired him April 20 after an internal-affairs investigation found he had misused its Flock automated license-plate-reader system to track his ex-wife. Internal affairs documents reviewed by KHOU show Rodriguez searched his ex-wife's license plate through Flock 2,386 times over roughly an 11-month period; the stalking indictment separately accuses him of placing a physical GPS tracking device on her vehicle. Court records show the specific charged conduct occurred between November 2, 2024, and April 2, 2025. [1, 2, 3, 4]

His ex-wife, Kayland Johnson, first reported to Katy police in October 2025 that Rodriguez was somehow tracking her whereabouts; the department suspended him, opened an investigation, and turned its findings over to the Fort Bend County District Attorney's Office. During that investigation Rodriguez admitted to using Flock to track Johnson, calling it a "dumb decision" with "no excuse." Fort Bend County Second Assistant DA Wesley Wittig said this was the first case his office has charged for Flock misuse; Rodriguez faces up to 10 years in prison and thousands of dollars in fines on each count.

Katy police said the Flock system requires officers to log a reason for each search and creates a "permanent, unalterable" digital audit trail -- the same audit trail investigators used to build the case against Rodriguez -- and that it conducts monthly random audits and quarterly audits of all officers with search access, restricted to officers in investigative roles. The department said it has used Flock for five years and credited it with solving hundreds of crimes annually, while stating it remains "committed to protecting our community while fiercely guarding the privacy and civil liberties of every resident."
