On March 21, 2021, 30-year-old Mai Rue Lily Vang was shot and killed in the Wausau apartment she shared with her boyfriend. Known as Lily, she was a mother of four and a nail artist whose family remembered her home-cooked meals and nurturing presence. Her body was found in her bedroom; her two youngest children were in the home but were not physically harmed.

The man identified as the prime suspect, 26-year-old Umberto Lo, had a documented history of domestic abuse involving Vang and was under court orders to have no contact with her. Lo reportedly sent a photograph of Vang’s injury to a family member, who then contacted police. Lo was arrested at the apartment without incident and charged with first-degree intentional homicide; he was scheduled for a psychiatric evaluation during the proceedings.

Anyone who knew Lily, her family, or had information about the relationship or the days leading up to March 21, 2021, is asked to come forward with what they remember.
