Over the course of more than 20 years, Joachim Kroll murdered 14 people, including very young girls, making him one of the most disturbing German serial killers in the country's history. Not content just to end the lives of his victims, Kroll repeatedly ate the flesh of the people he killed, leading him to be called the Duisburg Man-Eater and the Ruhr Cannibal.
After getting away with murder for more than two decades, Kroll's revolting crimes were finally discovered when law enforcement found him cooking the remains of a young girl in his apartment. Kroll, who was called "Uncle Joachim" by the neighborhood children who adored him, is one of the first known German cannibals and serial killers, eventually joined by infamous German murderers Armin Miewes and Volker Eckert.
The Strange And Shocking Case Of Joachim Kroll, The Duisburg Man-Eater,
He Mutilated His Victims
After killing his victims, Joachim Kroll often mutilated their corpses, leaving behind particularly bloody and gruesome crime scenes. In the case of his first victim, Irmgard Strehl, after strangling the 19-year-old to death, he used a long-bladed knife to disembowel the teenager, while after he murdered and raped 16-year-old Manuela Knodt in July 1956, he cut pieces of flesh from the teenager’s body.
After mutilating Knodt’s corpse, Kroll masturbated over the 16-year-old’s lifeless and blood-soaked body, leaving large quantities of semen on the girl’s genitals and face. Consequently, officers first assumed Knodt had been killed by several different men, not a single serial killer like Kroll. However, the reason he cut the flesh from the teenager’s body was even more disturbing than the grisly mutilation he perpetrated.
He Committed Necrophilia
In the case of five-year-old Ilona Harke, as well as the majority of Joachim Kroll’s victims, raped the child’s lifeless body after killing her. In fact, most of the women and girls he attacked were either dead or unconscious when he raped them, indicating Kroll was a necrophile who enjoyed having sex with people who could not resist or reject him.
However, while he raped the corpses of his victims, some of whom were very young children, necrophilia wasn’t even the most disturbing act he subjected the girls and women to after their deaths.
He Murdered At Least 13 Women And Girls
With the murder of Irmgard Strehl, Joachim Kroll began a killing spree that lasted more than 20 years and resulted in the untimely deaths of 13 women and girls. His victims ranged in age from four to 61, although the majority of the people Kroll murdered were young girls who were around 12 years old. As with Strehl, Kroll attacked most of his victims when they were traveling to school or home or walking through parks, wooded areas, and fields.
He killed the majority of the young women and girls by strangling them to death his hands. However, in the case of Petra Giese, he used the 13-year-old’s own scarf to strangle her to death on Easter Sunday in 1962. More than four years later, in December 1966, he killed five-year-old Ilona Harke by holding her head underwater in a stream simply because he wanted to know what it felt like to drown someone. Initially, people thought the child had accidentally fallen into the water and drowned, but an autopsy revealed evidence to indicate five-year-old Harke had been murdered.
He Murdered His First Known Victim Shortly After His Mother Died
Born on April 17, 1933, in Nazi Germany, Joachim Kroll was the youngest of eight children, and his father was a miner who was held as a prisoner of war during World War II. As a child, Kroll was smaller than his peers and frequently wet the bed.
Shortly after his mother passed away in 1955, Kroll, who was 22 at the time, committed his first known murder when he attacked Irmgard Strehl, 19, while the young woman was walking on a street in the village of Walstedde. After strangling the teenager to death with his hands, Kroll subjected her corpse to horrifying acts that became signature aspects of his future killings.
He Told A Neighbor His Toilet Was Clogged With Guts
Joachim Kroll’s 21-year-reign of murder, necrophilia, mutilation, and cannibalism finally came to an end after a plumbing problem brought his gruesome deeds to light. In July 1993, the toilet in the bathroom Kroll shared with one of his neighbors wouldn’t flush, so the man asked Kroll if he knew what was wrong. Incredibly, Kroll told his neighbor the toilet was “clogged with guts.” Initially, the man didn’t make much of Kroll’s strange comment until police officers visited his home to find out if he knew anything about the recent disappearance of a local girl, four-year-old Monika Kettner.
When the neighbor told investigators about Kroll’s odd remark, the officers called a plumber to take apart the toilet in bathroom. To the shock and horror of everyone at the scene, the plumber discovered the toilet had been clogged with multiple internal organs, including a heart, a pair of lungs, a liver, and two kidneys.
Multiple Men Were Convicted Of The Murders He Committed
One of the reasons Joachim Kroll was able to kill 14 victims over the course of more than 20 years was because a number of other men were arrested and convicted of murders he’d actually committed. Six months after Kroll murdered, raped, mutilated, and cannibalized 15-year-old Manuel Knodt in July 1959, another man went to the police and confessed to killing the teenager. Even though he later told officers he hadn’t actually killed Knodt, the man was convicted of the 16-year-old's murder and sentenced to eight years in prison.
After Kroll killed Petra Giese on Easter in 1962, another man, Vinzenz Kuenh, was arrested and sent to jail for murdering the 13-year-old. Another man, Walter Quicker, was accused of murdering one of Kroll’s victims, 13-year-old Monika Tafel, but the authorities weren’t able to convict Quicker of the teenager’s murder. However, Quicker’s neighbors were certain he was responsible for killing the girl, and the falsely accused man committed suicide after he was ostracized by his community.
Yet another local man, Adolf Schickel, killed himself after he was blamed for a murder perpetrated by Kroll. In September 1966, Kroll killed Schickel’s 20-year-old girlfriend Ursula Rohling. Despite Schickel having absolutely no involvement in the young woman’s murder, people were convinced he’d killed Rohling, so his grief and the accusations caused him to jump off of a bridge to his death.
He Had A Rubber Sex Doll
In addition to his expansive collection of children’s dolls, Joachim Kroll had a life-sized rubber figure that he regularly used for his sexual satisfaction. According to Kroll, after he murdered a victim and raped her dead body, he would return to his apartment and have sex with the rubber doll while he relived the violent acts he’d just committed.
The German serial killer also confessed that he would often choke the doll with his hands while he had sex with it. However, the life-sized rubber sex doll was far from the most disturbing item investigators found when they visited Kroll’s home.
He Collected Dolls And Used Them To Rehearse Killing Children
Joachim Kroll was well-known by the children is his neighborhood, and he often went for walks with little girls. Incredibly, while he murdered several children, including girls as young as four and five, many of these neighborhood children returned from their jaunts with Kroll completely unharmed.
In addition to giving candy to the kids in the neighborhood to win their affections, Kroll also collected dolls which he would use to help him become acquainted with young girls. He also used these dolls, which were the size of small children, to fulfill his violent fantasies and practice murdering his victims: Kroll choked the figures while he masturbated, providing himself with a perverse and frightening thrill.
He Killed One Male Victim
While most of the people Joachim Kroll murdered were women and young girls, he did kill one male victim, 25-year-old Hermann Schmitz, on August 22, 1965. Schmittz had parked by a lake close to the city of Duisburg, and he was sitting in his car with his girlfriend, Marion Veen. Kroll approached the vehicle and used his knife to deflate one of the tires; then he stabbed Schmittz multiple times in the heart when the 25-year-old exited his car to investigate the damage.
Miraculously, Veen was able to flee the scene in the her boyfriend’s vehicle before Kroll attacked her, but Schmittz died from his injuries, making the young man the only known male victim of the Duisburg Man-Eater.
He Cannibalized His Victims
After cutting flesh from Manual Knodt’s dead body, Joachim Kroll took the pieces of the 16-year-old’s buttocks back to his home, cooked the cuts of meat, and ate them. After experimenting with cannibalism for the first time, Kroll must have developed a taste for human flesh, because he went on to eat more pieces of meat he’d taken from his victims’ bodies.
After killing 13-year-old Petra Giese in April 1962 by strangling her to death with her own scarf, he used his knife to cut off sections of the girl’s hand, forearm, and buttocks. Just months after murdering Giese, he strangled 12-year-old Monika Tafel in June 1962. After killing the child, he raped her body and cut pieces of flesh from her thighs and buttocks, and some experts concluded he may have even eaten consumed some of Tafel’s raw tissue at the murder scene.
