At just 20 years old, Sef Gonzales murdered his entire family, his father Teodoro, mother Mary Loiva, and 18-year-old sister Clodine, in their Sydney home in 2001.

Struggling with an identity crisis, failing his medical exams, and facing rejection from his parents, who planned to disown him and cut off his inheritance, Sef devised a chilling plan. He brutally killed them and tried to stage the scene as a racially motivated hate crime. But the truth soon unravelled.

Nick Kaldas, then head of the New South Wales Homicide Squad, led the investigation that ultimately brought Sef Gonzales to justice. You can find his book, Behind the Badge, here.
