A Milwaukee County jury on Friday convicted 22-year-old Tamirat Mills of two counts of first-degree intentional homicide and one count of taking and driving a vehicle without the owner's consent in the 2022 killings of brothers Amarion Brown and Charlus Robinson in Brown Deer. The verdict followed a multi-day trial in Milwaukee County where prosecutors leaned heavily on electronic records and witness identifications. Mills is scheduled to return to court for a sentencing hearing on May 7, as per CBS 58.
Officers were called to the family home on the morning of Sept. 1, 2022, after a relative found Amarion Brown unresponsive inside. Police later discovered Charlus Robinson in a vehicle parked in the driveway. The killings triggered a wide-ranging probe that pulled in surveillance footage, phone data and vehicle evidence, according to CBS 58.
Investigation and evidence
At trial, prosecutors told jurors that a civilian witness identified Mills and co-defendant Joseph Tucker from booking photos and surveillance images, and that Mills made a recorded jail call that was referenced in court filings. They presented records showing Mills booked a ride near the house on the morning of the killings, highlighted Cash App transfers that connected the two men, and introduced cellphone location data that placed Mills near the spot where the family's Jeep was later found. The Wisconsin State Crime Laboratory, prosecutors said, reported "very strong support" that Tucker was part of a DNA mixture from the vehicle and "moderate support" that Mills was in the same mixture, which prosecutors argued backed up their timeline of events, according to FOX6 News Milwaukee.
Earlier charges and arrests
Mills was formally charged in January 2025 after investigators relied on tips from a confidential informant and a citizen witness to narrow down potential suspects. Those developments and earlier milestones in the case had been laid out in prior coverage of the investigation. As surveillance and electronic records were reported, prosecutors have consistently described those materials, as reflected in court filings, as central to building their case.
What's next
Mills is due back in Milwaukee County court on May 7 for sentencing, when the judge is expected to hear victim-impact statements along with arguments from both sides before deciding on the punishment. Co-defendant Joseph Tucker has already been sentenced to two consecutive life terms in connection with the killings, which leaves Mills facing Wisconsin's most serious homicide penalty if the judge orders a life sentence, according to FOX6 News Milwaukee.
Legal implications
Under Wisconsin law, first-degree intentional homicide is a Class A felony that carries a life sentence, and judges have limited discretion to impose lesser terms on that charge. The statutory language and related jury instructions spell out how the life sentence penalty applies in these cases; see the relevant Wisconsin statutes for details.
