Fritz Haarmann: The Butcher of Hanover - The Gruesome Tale of a Serial Killer


The story of Fritz Haarmann, a notorious German serial killer known as “The Butcher of Hanover,” is a chilling account of unimaginable horror and depravity. Haarmann was responsible for the brutal murders of at least 24 young men and boys between 1918 and 1924, although he later claimed to have killed many more. His heinous crimes, which involved sexual assault, dismemberment, and the disposal of his victims’ bodies, horrified a nation and led to one of the most sensational criminal trials in modern German history. Let us explore not only the depths of Haarmann’s evil but also the involvement of his alleged accomplice, Hans Grans, and the grim aftermath of their reign of terror.


Early Life and Criminal Beginnings

Friedrich Heinrich Karl “Fritz” Haarmann was born on 25 October 1879 in Hanover, Germany, into a troubled household. His father, Ollie Haarmann, was an abusive man who despised Fritz for his effeminate mannerisms and apparent lack of interest in traditional masculine pursuits. As a child, Haarmann was frequently ill and experienced difficulties in school, later becoming a troublemaker and delinquent. By his early twenties, Haarmann had already faced multiple run-ins with the law, including charges of burglary, theft, and even sexual assault. His criminal record and deviant behavior set the stage for the gruesome path he would embark upon in later years.


Criminal Evolution and Exploitation of Vulnerable Victims

The true horror of Haarmann’s life began after World War I when he became a police informant in Hanover. He cleverly used this position to shield himself from suspicion while engaging in illegal activities, including human trafficking and the exploitation of vulnerable boys and young men. Haarmann targeted young males, many of whom were destitute or runaway youths lured by the promise of food, shelter, and work. Once in Haarmann’s clutches, these boys were subjected to a nightmare of sexual abuse, torture, and ultimately, death.



His modus operandi was as grotesque as it was chilling. Haarmann would strangle or bite through his victims’ Adam’s apple, killing them in the throes of what he described as “rabid sexual passion.” Afterward, he would dismember their bodies in his attic apartment, pouring strong black coffee to fortify himself for the gruesome task. The corpses would be carefully and methodically carved up, with the flesh being either discarded in the Leine River or, as was alleged but never proven, sold as contraband meat. Haarmann claimed to have disposed of his victims’ remains in the Leine River, while their clothing and belongings were often kept as trophies or sold to unwitting buyers.


Among the most harrowing aspects of the case was the fact that many of Haarmann’s victims were homeless, jobless, or otherwise socially isolated, making them easy prey for a man who had mastered the art of deceit and manipulation. His preferred targets were typically boys and young men between the ages of 13 and 20, and their disappearance often went unnoticed by society at large. However, over time, as more and more families reported their loved ones missing, the noose began to tighten around Haarmann.

Arrest and the Search of His Apartment

Following the arrest of Haarmann on 22 June 1924, the police conducted a thorough search of his attic apartment at No. 2 Rote Reihe in Hanover. What they uncovered was nothing short of nightmarish. The flooring, walls, and bedding within the single-room apartment were found to be extensively bloodstained, which Haarmann attempted to explain away as a result of his illicit meat trade. However, as the investigation deepened, it became increasingly clear that the blood was the residue of unimaginable violence.

Several of Haarmann’s neighbours and acquaintances were questioned by detectives and revealed disturbing insights into his activities. Many neighbors had seen teenage boys entering Haarmann’s apartment but rarely leaving. Some witnesses even reported seeing him leaving his apartment late at night with sacks or bags, which he would discard in the Leine River. Two tenants discreetly followed Haarmann one night and observed him disposing of a heavy sack into the river, further corroborating suspicions about his murderous activities.

The clothes and personal possessions found at Haarmann’s apartment, as well as those in the possession of his acquaintances, were believed to belong to missing youths. These items were confiscated and put on display at the Hanover Police Station. As more and more family members identified the possessions of their missing loved ones, the net around Haarmann tightened.


The Damning Evidence and Confession

The turning point in the investigation came on 29 June 1924, when several personal items found at Haarmann’s apartment, including clothes, boots, and keys, were identified as belonging to a missing 18-year-old named Robert Witzel. Additionally, a skull found in a garden on 20 May 1924 was identified as Witzel’s. With this damning evidence, Haarmann could no longer maintain his innocence. When confronted with witnesses and further proof of his crimes, he broke down and confessed.

Haarmann admitted to murdering between 50 and 70 boys and young men, although he was only charged with 27 killings. He insisted that he never intended to murder his victims but was overcome by a compulsive desire to bite through their Adam’s apples during sexual encounters. Haarmann described his acts as driven by uncontrollable passion, stating that the thrill of the kill was stronger than the horror of dismembering the bodies. He recounted how he would spend up to two days dismembering his victims’ bodies, disposing of the remains by either flushing them down the toilet or throwing them into the river.

Hans Grans: The Accomplice or the Opportunist?

Hans Grans, Haarmann’s alleged accomplice, was a young drifter whom Haarmann met in 1922. Grans was initially a lover of Haarmann and later became involved in his criminal activities, although his exact role remains disputed. Some sources suggest that Grans actively encouraged Haarmann to murder, while others claim he was more of an opportunist who capitalized on the deaths by selling the victims’ belongings.

Grans was arrested on 8 July 1924 and charged with being an accessory to several murders. According to Haarmann, Grans had specifically urged him to kill at least two of the victims, including Adolf Hannappel, for personal gain. Witnesses testified that they had seen Grans pointing out potential victims to Haarmann and that he had profited from the sale of clothing and other items belonging to the murdered boys.


During the trial, Grans maintained his innocence, claiming that while he may have been complicit in the theft and resale of stolen goods, he never participated in the murders themselves. However, the evidence against him, including a handwritten note implicating him in the murder of Fritz Wittig, was damning. Grans was ultimately found guilty of incitement to murder in the case of Adolf Hannappel and sentenced to death by beheading. He also received a 12-year sentence for his involvement in the murder of Fritz Wittig.



Despite his conviction, Grans managed to avoid execution. After a lengthy appeal process, his death sentence was commuted to life imprisonment, and he was released in 1939. Grans went on to live quietly until his death in the 1970s, always maintaining that he was an innocent man wrongfully convicted of crimes he did not commit.

Trial and Execution

Haarmann’s trial began on 4 December 1924 and quickly became a media sensation, drawing massive public and press attention from around the world. Haarmann was charged with the murder of 27 boys and young men. Despite his attempts to feign indifference to the proceedings, Haarmann’s demeanor wavered under the weight of the evidence presented against him. Hundreds of bones, personal items, and testimonies tied him unequivocally to the murders. Throughout the trial, he often expressed uncertainty about the identity of many of his victims, shrugging off the severity of his crimes and claiming that he could not recall their faces.

"Condemn me to death. I ask only for justice. I am not mad. Make it short; make it soon. Deliver me from this life, which is a torment. I will not petition for mercy, nor will I appeal. I want to pass just one more merry night in my cell, with coffee, cheese and cigars, after which I will curse my father and go to my execution as if it were a wedding."

On 19 December 1924, Haarmann was found guilty of 24 of the 27 murders and was sentenced to death by beheading. When he heard the sentence, Haarmann stood before the court and stated, “I accept the verdict fully and freely,” adding that he would go “joyfully and happily” to the guillotine.

Often, after I had killed, I pleaded to be put away in a military asylum, but not a madhouse. If [Hans] Grans had really loved me he would have been able to save me. Believe me, I'm not ill — it's only that I occasionally have funny turns. I want to be beheaded. It'll only take a moment, then I'll be at peace.

At 6 o'clock on the morning of 15 April 1925, Haarmann was beheaded by guillotine in the grounds of Hanover prison. His executioner was Carl Gröpler. In accordance with German tradition, Haarmann was not informed of his execution date until the prior evening. Upon receipt of the news, he observed prayer with his pastor, before being granted his final wishes of an expensive cigar to smoke and Brazilian coffee to drink in his cell.



No members of the press were permitted to witness the execution, and the event was seen by only a handful of witnesses. According to published reports, although Haarmann was pale and nervous, he maintained a sense of bravado as he walked to the guillotine. The last words Haarmann spoke were: "I am guilty, gentlemen, but, hard though it may be, I want to die as a man." Immediately prior to placing his head upon the execution apparatus, Haarmann added:

"I repent, but I do not fear death."

The Grim Fate of Haarmann’s Head

Haarmann was executed by guillotine on 15 April 1925 at Hanover prison. His last words were: “I am guilty, gentlemen, but, hard though it may be, I want to die as a man.” After his execution, Haarmann’s head was preserved in formaldehyde for study by scientists interested in uncovering any abnormalities that might explain his monstrous behavior. His head was kept at the Göttingen medical school for decades, where it was studied by various experts.


It wasn’t until 2014 that Haarmann’s head was finally cremated, bringing an end to its macabre post-mortem existence. The mystery and horror surrounding his crimes, however, continue to fascinate and terrify those who delve into the dark history of one of Germany’s most infamous serial killers.
