Former Katy Police Department officer Sergio Guadalupe Rodriguez has been charged in Fort Bend County with third-degree felony charges of stalking and misuse of official information, according to multiple media outlets across the Houston area in late August. Both cases are pending.

Rogriguez was a ten-year veteran of the department, KPD Chief Bryon Woytek confirmed.

In October 2025, Katy Police received a formal complaint regarding Rodriguez, according to a KPD statement. The complaint, which was filed by the officer’s ex-wife, alleged that the officer was somehow tracking her whereabouts. An investigation was immediately initiated into the allegations, and through this investigation officials learned that the officer had misused the Flock system to run his ex-wife's vehicle license plate. The officer was immediately suspended, and the findings of the investigation were turned over to the Fort Bend County District Attorney's Office. The officer was ultimately terminated and he was criminally charged with Misuse of Official Information and Stalking.

“The use of the Flock camera system, along with other investigative tools that are used by police officers are strictly for authorized law enforcement investigations only,” KPD said in a statement sent to media outlets. “Ironically, the Flock camera system that was abused is the same system that was used to bring formal charges against the officer.”

The Katy Police Department has used the Flock system for the last five years, according to the statement.

“We have been able to solve hundreds of crimes each year with the use of this technology; it has been one of the best crime-fighting tools developed in modern policing,” the department statement said. “We recognize that adopting advanced public safety technology requires a foundation of absolute transparency and strict oversight. To ensure our automated license plate readers (LPRs) are used ethically and responsibly, we have established rigorous operational safeguards.”

“Flock Safety has assisted us with a very robust analytic system that creates a permanent, unalterable digital audit trail of who conducted the search, when it occurred, and why,” the statement said. “Flock has since put in place an updated system that reviews itself and monitors abnormal search behaviors and, if found, will trigger immediate, automatic lockouts and immediate reporting.”

The department has put its own internal audits in place, done by the Chief of Police and command staff. On a monthly basis, the department audits a random sample of officers, and a quarterly audit is done on all officers that have search capabilities. The search capabilities of the system are restricted to officers with an investigative role; not every patrol officer has search capabilities on the Flock system, the department said.

“We continue to hold our officers to the absolute highest ethical and professional standards,” the department said. “Abuse or misuse of this technology will not be tolerated. Any violation of our strict

usage policies will result in immediate termination of system access and swift disciplinary action, up to and including termination of employment and legal prosecution.”
