A suspect, 33-year-old Maxwell Steven Anderson (born May 26, 1990), a longtime
Waukesha County resident, was arrested on April 4 and held in custody until he was formally charged on April 12 with first-degree intentional homicide, mutilating a corpse, and arson. Anderson resided in
Pewaukee, Wisconsin, throughout most of his life, and briefly served in the
United States Navy from April 2011 to January 2012. The circumstances of his discharge remain unclear. In recent years prior to the murder, Anderson worked as a bartender at several Milwaukee establishments. Before Robinson's death, she and Anderson were seen going on a date at a seafood restaurant where he used to work. When police searched Anderson's home, they reportedly found blood on the walls. The blood was tested, and it was determined that it was not Sade's blood and was later confirmed to be canine according to police reports. On April 18, 2024, a passerby walking along a
Lake Michigan beach found a torso and arm, which have been tested and confirmed to be Robinson's. Nearly a month after this, a human arm was discovered along the shoreline at the Waukegan Municipal Beach. The arm was confirmed to be Robinson's. Anderson's motive for killing Robinson remains unknown. On June 6, 2025, a jury found Anderson guilty on all counts. On August 1, Anderson was sentenced to life in prison for the murder. Maxwell is currently incarcerated at
Dodge Correctional Institution in
Waupun. ==Responses==
