Former Katy police officer Sergio Rodriguez faces up to 10 years in prison after allegedly using license plate reader cameras 2,386 times to track his ex-wife's movements. He has pleaded not guilty.
Rodriguez is charged with two third-degree felonies in Fort Bend County: stalking and misuse of official information. He is due back in court in September 2026, Houston Public Media reported on Tuesday, Aug. 25.
Between November 2024 and April 2025, Rodriguez allegedly used Flock cameras to monitor his ex-wife's location and placed a separate tracking device on her vehicle, according to Fort Bend County court records. Internal affairs documents obtained by KHOU 11 show he searched her license plate 2,386 times over an 11-month period.
After his ex-wife filed a formal complaint in October 2025, Rodriguez was interviewed and allegedly admitted to the tracking, calling it a "dumb decision" and saying he had no excuse, according to the internal affairs documents. The Katy Police Department suspended him immediately.
After an investigation with the Fort Bend County District Attorney's Office, Rodriguez was indicted April 6 and fired from the department on April 20.
The Fort Bend County Sheriff's Office arrested Rodriguez in early May 2026. He was released by the end of that month on a $30,000 bond with a no-contact order barring him from communicating with his ex-wife.
Fort Bend County Second Assistant District Attorney Wesley Wittig told KHOU 11 that this is the first time his office has charged someone with misusing the Flock camera system. "No matter who breaks the law, they have to be held accountable," Wittig said.
Flock announces safeguards after misuse cases
The Rodriguez case is not isolated. Officers in Baytown, Pasadena and Deer Park have also faced Flock misuse investigations in recent weeks, and a Fort Bend County Sheriff's deputy was suspended for looking up one person's plate 41 times and another's 148 times, according to ABC 13.
In response, Flock Safety announced platform changes on Aug. 13. The company said it will require officers to enter a case code before running any search and make its Audit Assistance misuse-detection tool mandatory for all law enforcement customers by the end of 2026. Flock also recommended shortening default data retention from 30 days to seven days and introduced an "Evidence Mode" to preserve data tied to active investigations. The changes include automatic lockouts when abnormal search behavior is detected.
The Katy Police Department said in a statement that it has used Flock for five years and credits the system with solving hundreds of crimes annually. The department said it maintains a digital audit trail it described as permanent and unalterable for all searches.
An attorney representing Rodriguez was not immediately available for comment, according to Houston Public Media. Flock Safety did not respond to the outlet's request for comment on the case.
