Katherine Knight: Australia’s Cannibal Killer

Katherine Knight’s story is one that chills you to the bone — not just because of the horrific murder she committed, but because of how deeply she was shaped by her traumatic, disturbing upbringing. To understand the horrific crime she committed in 2000, we need to take a look at the twisted, often violent life that led her to become Australia’s most infamous female killer.

Early Life: A History of Abuse

Born in 1955 in the small town of Tenterfield, New South Wales, Katherine Mary Knight had an unremarkable beginning, but her childhood was anything but ordinary. She was one of five children born to a violent and abusive relationship between her parents, Barbara and Jack Knight. Her mother, Barbara, was reportedly an alcoholic who had little to no maternal affection to offer her children. Her father, Jack, was even worse — a tyrant who frequently abused his wife and children.

Katherine’s father, however, was the real source of her nightmares. He had an affinity for violence, and Katherine was one of his primary targets. He would take her into his bedroom and make her watch as he physically assaulted her mother. Even worse, Katherine later revealed that her father sexually abused her as well. This abuse cast a long shadow over her entire life, shaping her behavior and emotional responses to the world around her. The toxic home environment left Katherine angry, confused, and emotionally scarred.

At school, Katherine was bullied and ostracized, further isolating her from the rest of society. Her peers saw her as a strange and unfriendly girl. This rejection only added to her growing feelings of resentment and anger, feelings she would eventually take out on the world around her in the most horrifying way possible. The seeds of violence were planted early, though they would not sprout until later in her adult life.

First Signs of Trouble

In her late teens, Katherine’s behavior began to show the first signs of her deteriorating mental state. At the age of 15, she dropped out of school and took a job as a butcher’s assistant. She was an ambitious young woman who wanted to carve out her own future, but her relationships with men soon began to mirror the dysfunction she had grown up with.

Katherine’s first serious relationship was with a man named David Kellett, with whom she had two children. Unfortunately, the relationship quickly soured. Katherine’s violent temper, already beginning to show, surfaced in a terrifying way. She once stabbed David in the stomach with a pair of scissors during an argument. Despite the physical and emotional violence, she kept her relationship with David going until it fell apart when he left her for another woman.

This pattern of unhealthy, abusive relationships continued throughout Katherine’s life. She would go on to have several more failed relationships, each ending in disaster, with Katherine’s volatile, controlling nature becoming more pronounced as time went on. She was unable to maintain a stable romantic relationship, and the men she chose were often drawn to her because of her beauty or her domineering, take-charge attitude. But the controlling behavior that came with her love was suffocating, and each relationship left her even more unhinged.

Her Relationship with John Price

By 1998, Katherine had found her next partner — John Price, a well-liked, successful miner from Aberdeen, New South Wales. Price and Katherine seemed to be a good match, at least initially. They lived together in a house in Aberdeen, where Price’s three children from a previous marriage were already living. Katherine seemed to take to her role as a mother figure to the children. However, as with all of Katherine’s relationships, the darkness simmered just beneath the surface.

Price was no stranger to Katherine’s violent tendencies. She had threatened him before, even stabbing him in a fit of rage when they had an argument. He had once kicked her out of the house after she assaulted him, and while they reconciled shortly after, the relationship was anything but stable. Price knew that Katherine had a temper, but he never imagined it would go this far.

By early 2000, things between Katherine and Price were at their worst. Katherine became increasingly possessive and jealous, suspecting Price of cheating on her, though there was no evidence of infidelity. The tension reached a boiling point when Price decided he had had enough of her abusive behavior. He told Katherine he was ending the relationship and would be moving out of the house.

This decision would prove to be fatal.

The Night of the Murder

On February 29, 2000, Katherine and John Price had a final confrontation. Price, after a night of drinking, arrived home to find Katherine in a volatile mood. He had made it clear to her that their relationship was over, but this was something Katherine could not accept. In her mind, John Price belonged to her, and she would do whatever it took to keep him.

The evening of the murder was filled with tension. Katherine and Price fought over his decision to leave, and at some point during the argument, Katherine snapped. She grabbed a knife from the kitchen and attacked Price. She stabbed him repeatedly, and when he collapsed, she continued to mutilate his body in a gruesome display of rage.

Katherine wasn’t finished, though. After the murder, she took things to an unthinkable level. She dismembered John Price’s body, using her knowledge as a butcher. She cut him into pieces, and in a macabre twist, she cooked parts of his flesh. Katherine then set the table, preparing a meal as if she was going to serve it to someone — specifically, Price’s children. She even placed the cooked body parts on the dining table with a gruesome note.

Katherine’s chilling actions didn’t stop there. She placed John Price’s head in a pot on the stove, and the remains were placed in the fridge. She then took a shower to clean herself up, but she wasn’t finished with her twisted plan. She eventually fell asleep, waiting for the authorities to arrive.

The Discovery and Arrest

The following day, Katherine’s crime was discovered when a neighbor, concerned after not seeing Price for a while, went to check on him. When they entered the house, they were horrified by what they saw. Price’s mutilated body was found in the bedroom, and the rest of the house was filled with the stench of cooking flesh. It was one of the most grotesque crime scenes Australia had ever witnessed.

Katherine was arrested the following day. She had no remorse, and in fact, she had told a psychiatrist that she had no memory of what had transpired the night before. The details of her actions were so horrific that they shocked even hardened detectives. Katherine Knight, once a victim of abuse herself, had turned into a monstrous perpetrator.

Trial and Conviction

At her trial, Katherine Knight pleaded guilty to the murder of John Price. The court, however, found her to be of sound mind during the commission of the crime, despite her claims of memory loss. Her actions were deemed premeditated and deliberate, and she was sentenced to life imprisonment without the possibility of parole. Katherine Knight became one of the few women in Australian history to receive such a sentence.

Her story is one of tragedy and horror, a chilling reminder of how cycles of abuse, neglect, and trauma can manifest in unimaginable ways. Katherine Knight’s brutal crime is a grim testament to how deeply the scars of childhood can shape a person’s future. What began as a cycle of violence and dysfunction came to a horrific climax with the brutal murder of an innocent man. And Katherine Knight’s name would go down in history as one of Australia’s most notorious killers — forever associated with the label of “cannibal killer.”

As of today, Katherine remains in prison, where she is serving out her sentence. The horrors of her past and the brutality of her crime continue to haunt the country and those who remember the chilling details of that fateful night in 2000.
