Milwaukee experienced a sharp rise in homicides in 2021 and a heavy caseload for investigators; by October of that year, roughly half of the city’s murders remained unsolved. It is not known whether Cooper’s death was related to that broader surge in violence. If anyone knew Jack or has information about his death, please share what can help clarify what happened.
