Josue Ayala has resigned from the Milwaukee Police Department days after he was charged with a crime over his alleged misuse of license plate-reading Flock technology.

Ayala, 33, pleaded not guilty to one count of attempted misconduct in public office during his initial court appearance on March 4.

The charge is a misdemeanor that carries a potential maximum penalty of nine months in jail and $10,000 fine.

Milwaukee is one in a growing number of communities nationally that have started using Flock cameras to help locate stolen vehicles, identify vehicles used in violent crimes, and track vehicles associated with missing persons. The technology is controversial and been criticized by civil rights and privacy advocates.

Conducting searches for personal reasons is a violation of department policies.

Prosecutors say Ayala used the Flock camera system while on duty more than 120 times to look up the license plate of someone he was dating. They believe Flock technology also was used on a second license plate, one belonging to that person’s ex, 55 times, according to a criminal complaint, filed Feb. 24 in Milwaukee County Circuit Court.

Ayala joined the Milwaukee Police Department in 2017, and his total gross pay was about $120,000 in 2024, according to the most recent city salary data available. 

Milwaukee police confirmed in a March 4 email to the Milwaukee Journal Sentinel that Ayala has resigned from the department.

Ayala and his attorney Michael J. Steinle, of Milwaukee, would not speak to reporters as they left the courtroom.

Prosecutors say the department became aware of the allegations against Ayala after a driver saw that they were the subject of searches through the website, www.haveibeenflocked.com, which collects and publishes “audit logs” of searches of the Flock system by police agencies.

The driver saw that Ayala had searched the plate numerous times, which prompted the driver to file a complaint with the Milwaukee Police Department.

Detectives then audited Ayala’s searches in the Flock system from March 26, 2025, through May 26, 2025.

Ayala is at least the second Wisconsin officer to face criminal charges for misuse of the Flock system. A Menasha police officer was charged in January for tracking an ex-girlfriend’s car.

Milwaukee police began using Flock cameras in 2022. MPD has a $182,900 contract with Flock for the use of the technology. That contract is active through January 2027.

Court Commissioner Dewey B. Martin released Ayala on a $2,500 signature bond March 4.

Signature bonds, sometimes referred to as a personal recognizance bond, allow a defendant to leave custody without paying cash as long as they sign a promise to appear for their upcoming court dates.

Martin also ordered Ayala not to contact the two victims in the case.

Ayala also must report to the Milwaukee County Jail to be booked on March 9. If he doesn’t show up, a bench warrant will be issued for his arrest.

Ayala is scheduled to appear for a pre-trial conference on April 17.
