2nd man found guilty in 2022 deaths of Brown Deer brothers

A 20-year-old man is the second person convicted of playing a role in the violent killing of two Brown Deer brothers nearly four years ago. A Milwaukee County jury found Tamirat T. Mills guilty of two counts of first-degree intentional homicide in the Sept. 1, 2022, deaths of Amario Brown and Charlus Robinson, both 18. Online court records show the verdict was handed down on March 20. A separate jury in May also found Joseph A. Tucker guilty in the slayings. Prosecutors were aided in their case by using cellphone records and other electronic evidence to connect Mills and Tucker to the shootings. Here's what prosecutors say happened that night According to a criminal complaint, Brown Deer police were sent to the 8000 block of North 62nd Street. There, they found the brothers dead and the teens' mother reported her SUV had been stolen. Tucker was a friend of the brothers, whom their mother knew as "Joe." Joe spent the night at their home. The woman said in the document she thought she heard a "pop" around 5 to 6 a.m., but went back to sleep because she wasn't sure where it came from. The woman told investigators when she woke up, Joe was gone. She said her daughter later went to wake up Amarion and found that he had been shot. Another person inside the home woke up to the sound of the back door opening and a loud revving noise around 4 to 5 a.m., the document reads. That witness saw the woman's Jeep was gone, and assumed either Amarion or Charlus was using it. Officers discovered Robinson's body in the driver's seat of a vehicle parked in the driveway. Charlus died from two gunshot wounds to the head, an autopsy later showed. Phone records and other internet/network records show Tucker and Mills were both at the scene of the homicides around the time of the shooting, the criminal complaint reads. Surveillance footage also allegedly depicts both men taking the woman's Jeep before abandoning it later, according to the document. Tucker is now serving a life sentence in the brothers' killings. The jury also convicted Mills of taking and driving a vehicle without consent. Mills will be sentenced May 7 by Circuit Court Judge Michelle A. Havas. First-degree intentional homicide is a Class A felony and carries a mandatory life sentence. Chris Ramirez covers courts for the Milwaukee Journal Sentinel.
