Sophie’s father found her dead at the family’s Carrara home on Tuesday.
Detective Acting Inspector Kent Ellis described it as one of the most “confronting” scenes he had seen in his career.
Sophie’s mother, 46-year-old Yingying Xu, was arrested on a nearby street and charged with the girl’s murder.
This morning, Sophie’s school Emmanuel College will host a private service to honour her life, with hundreds expected to attend.
Members of the school community, including students and parents, have spoken in recent days about the impact that left them reeling.
Sophie has been remembered as bright and bubbly, with one peer saying she was “one of the smartest” students in school.
A candlelight vigil will also be held for Sophie in Emerald Lakes this afternoon.
