In this second part of I Catch Killers, Gary and Rojé delve deep into the chilling psyche of Katherine Knight—the only woman in Australia sentenced to life in prison without the possibility of parole.

What drives a person to commit the unthinkable? They explore the gruesome crime scene that shocked even the most veteran homicide detectives, the calculation behind the skinning and butchering of John Price, and the psychological "triggers" that Katherine used to justify her actions.

Gary and Rojé break down the terrifying final 24 hours of John Price's life, the warning signs that were missed, and the "nature vs. nurture" debate surrounding Knight’s fraternal twin sister. This is a gritty look into a real-life horror story and the long-term impact such extreme cases have on the detectives and communities left in their wake.
