RACINE, Wis. — Racine police say technology the city is preparing to remove helped investigators make two arrests in the fatal shooting of Koreem Ozier, a well-known local basketball player. Ozier was shot and killed Sunday night near 12th Street and Memorial Drive, police said. Chief Alex Ramirez said Tuesday that Flock’s sound-detection system alerted officers to the gunfire and that its automated license-plate readers helped investigators identify and locate a vehicle connected to the homicide. Ramirez said the information gave detectives an important lead as they worked to identify people connected to the shooting. Collin Wallace, 24, and Justin Millard, 23, were taken into custody and are expected to face charges, police said. The arrests came days after the Racine Common Council voted to end the city’s use of Flock cameras. The measure, approved Sept. 15 with Mayor Cory Mason casting the tie-breaking vote, gives the city 30 days to cover the cameras. Data may continue to be used for ongoing investigations during that period. Mason said he supports giving officers effective investigative tools but objected to information being collected and handled by a private company without sufficient transparency. In a statement after the arrests, he said technology used for public safety must protect civil liberties, include safeguards against abuse and prevent personal data from being sold for profit. Mason also pointed to an investigation involving a Racine police officer accused of misusing the technology as evidence that stronger oversight is necessary. He said the city was right to reconsider its relationship with Flock despite the system’s reported role in the homicide investigation. Alderman Malik Frazier said he recognized the technology’s potential benefits for law enforcement but remained concerned about how Flock handles collected data. He said he would be open to further discussions among the council, police and the public. Alderperson Olivia Turquoise-Davis similarly said the system’s apparent value in the Ozier investigation did not resolve the concerns behind the council’s decision. She called for clearer safeguards, transparency, oversight and accountability, arguing that public safety and responsible limits on surveillance should be pursued together. Flock systems have drawn growing scrutiny in Racine and other communities because license-plate readers can collect information about where vehicles travel and share that information through a private network. The debate in Racine now centers on whether those investigative benefits justify the privacy risks and whether local policies can adequately prevent misuse.
