Katherine Knight’s case remains one of the most disturbing crimes in Australian history. Before the murder, her relationship with John Price had been filled with volatility, breakups, and repeated warnings from friends and authorities about her escalating behavior. Despite this, Price allowed her back into his home shortly before the tragedy, hoping to keep the peace.

In February 2000, tensions between the two reached a breaking point. Price expressed fear for his safety, telling coworkers that Knight had become unpredictable and dangerous. He even attempted to end the relationship, but her threats and emotional manipulation made it difficult for him to fully distance himself. Those who knew him later said he seemed exhausted and anxious in the final days of his life.

One night, after another argument, Knight attacked Price in his own home. The assault was brutal and fatal, shocking even seasoned investigators. What followed was behavior that authorities later described as “beyond comprehension,” revealing the extent of Knight’s psychological instability and her capacity for extreme cruelty.

When police entered the home the next morning, the scene was unlike anything they had encountered before. Knight had staged parts of the house and prepared food using Price’s remains, seemingly intending to serve it to his family. This discovery stunned the entire community and quickly became one of the most infamous criminal cases the country had ever seen.

Katherine Knight was arrested, declared fit to stand trial, and ultimately became the first woman in Australia sentenced to life imprisonment without the possibility of parole. Her case is frequently cited in discussions of domestic violence, mental illness, and the warning signs that often precede extreme acts. Even decades later, it continues to serve as a grim reminder of how dangerous an unchecked spiral of abuse, obsession, and rage can become.
