Fired Milwaukee detective pleads not guilty to charges over alleged Flock database misuse

Former Milwaukee Police Department detective Tehrangi Chapman pleaded not guilty to two criminal charges, one a felony, tied to alleged misuse of the department's Flock license plate reader database. Prosecutors allege Chapman ran searches to track two people's movements 20 times for personal reasons and placed a GPS tracking device on a victim's car. MPD confirmed it fired Chapman the prior week. Court records indicate Chapman had been one of the internal affairs detectives assigned to investigate a separate former officer's misuse of the same system; the prosecutor said plea negotiations are underway, with terms undisclosed, and Chapman is due back in court in October.

Why this matters

The case is the second Milwaukee prosecution over personal use of the same ALPR database, and in both instances the misuse surfaced only after a victim came forward — raising questions about whether internal audits and search-window policies are sufficient safeguards in agencies that adopt the technology.
