More than 25,000 improper database searches, two years, one officer, and one conviction that USA TODAY Network describes as the first of its kind in the country.
Zachary Anthony Klein, an 11-year veteran of the Lufkin, Texas, Police Department, pleaded guilty on Sept. 30 to 100 felony counts of misuse of official information and was sentenced to five years in prison.
What 25,000 Searches Actually Looked Like
The sheer volume of Klein’s personal queries exposes how easily a powerful investigative tool can be turned against the people it was never meant to target.
Klein used Flock Safety‘s automated license plate recognition system and other restricted law-enforcement databases for personal purposes rather than casework. His targets were people connected to his private life, not active investigations.
Investigators from the Texas Rangers determined he monitored his former girlfriend, members of her family, and men she had dated. The pattern stretched across roughly two years.
Prosecutors focused the indictment on 100 counts representing the people he searched most frequently, out of a total query volume exceeding 25,000, according to reporting from the Lufkin Daily News and KTRE.
A lifetime protective order was subsequently issued for his former dating partner, with stalking cited as its underlying basis. That order is a court record distinct from the criminal plea. Klein’s attorney stated that the 100 counts to which his client pleaded guilty were for misuse of official information, not stalking, threats, or domestic violence. Prosecutors said investigators found evidence of threatening and controlling behavior, but those allegations did not become separate charges.
When Audits Watch the Department but Not the Officer
The mechanism that finally exposed Klein was a journalist’s inquiry, not the department’s own monitoring, and that gap is the real story here.
USA TODAY identified an unusual Flock search pattern and contacted the Lufkin Police Department. That external press inquiry led to an internal investigation, placed Klein on administrative leave, suspended the department’s Flock system, and brought in the Texas Rangers. The system remains offline with no announced reinstatement timeline.
Lufkin Police Chief Travis Brazil said earlier audits examined broad departmental activity rather than individual-user behavior. That gap made Klein’s searches difficult to distinguish from legitimate queries in the aggregate data.
It is, in effect, the oversight equivalent of checking whether a restaurant kitchen is busy without ever looking at what is actually on the plates. The auditing was real; it was simply aimed at the wrong level.
The collateral damage extends beyond Klein’s direct targets. Angelina County District Attorney Amy Wren said Klein was the lead investigator on an unrelated intoxicated-manslaughter case, and his credibility as a witness is now in question.
“He has affected at least one significant case in this office that may result in a victim getting no justice because of this.” Amy Wren, Angelina County District Attorney.
The Pattern Is Bigger Than One Officer
Klein’s conviction matters precisely because he is not the only officer under scrutiny: he is simply the first one a court has convicted.
According to USA TODAY Network reporting, at least 27 police or sheriff’s-office employees across seven states have been arrested, fired, placed on leave, or investigated after reporters identified suspicious Flock search patterns. Klein is the first among them to receive a criminal conviction.
Flock Safety PR manager Paris Lewbel said in a statement: “Any officer abuse of our system is completely unacceptable, and the people that abuse our system should absolutely be held accountable.” The company says its Audit Assistance feature, designed to flag abnormal search activity, will become mandatory for law-enforcement customers. Some agencies have already begun requiring detailed search justifications and case numbers for queries, according to CNN’s reporting.
That is a necessary start, but it does not close the gap. Independent user-level audits, automated anomaly detection, and transparent public reporting of search activity represent the credible next steps for meaningful accountability. Agencies should not wait for a surveillance app to surface the next Klein before acting.
Wren captured the core tension plainly: Flock has helped her office locate missing children and solve serious crimes. One officer’s misuse may now deny a separate victim their day in court. The tool has demonstrated real value; the oversight framework did not hold.
