Charlus Robinson, an 18-year-old Black male, was found dead in a car parked in the driveway of his family home near 62nd and Goodrich Lane in Brown Deer, Wisconsin, on September 1, 2022. Police were already at the residence earlier that morning after the mother discovered her other son, 18-year-old Amarion Brown, unresponsive in his bed from a gunshot wound. An autopsy later confirmed Charlus had been shot twice in the head.

Investigators focused on a friend called Joe, identified as Joseph Tucker, after piecing together cell phone records, app data, and surveillance footage that placed Tucker at the scene that morning. Surveillance also shows Tucker and another person, later identified as Tamirat T. Mills, stealing the family’s Jeep and abandoning it shortly afterward; a resident had heard a door open and a car revving between 4 and 5 a.m. and assumed a son was using the vehicle.

Joseph Tucker was arrested in February 2023 and charged with two counts of first-degree intentional homicide and operating a motor vehicle without the owner’s consent. Does anyone have information about the early-morning timeline or the people seen on the surveillance footage?
