Katherine Knight was born in 1955 and lived in Tenterfield, Australia. After dropping out of high school without having learned to read or write, Katherine was able to find employment at what she referred to as her "dream job", working at a local slaughterhouse. Katherine consistently found herself ruining her own relationships due to the abuse she would inflict on those closest to her, and this eventually culminated in one final plot for Katherine to get back at a man who refused to marry her.
