Marianne Bachmeier, known as “Revenge Mom,” shocked the world when she shot her daughter’s killer in court. Learn about her tragic past, the brutal murder of her daughter Anna, and the divided reaction to her act of vengeance.
On March 6, 1981, Marianne Bachmeier walked into a courtroom in Lübeck, Germany, with determination in her every step. A few minutes later, the world would be forever changed by her actions.
Marianne, whose 7-year-old daughter Anna had been brutally murdered by Klaus Grabowski, a convicted sex offender, took justice into her own hands in a shocking moment that has since become one of the most infamous acts of vigilante justice in modern history.

The Tragic Event that Led to Her Act of Revenge
Marianne Bachmeier’s life had already been filled with deep tragedy. A struggling single mother who ran a pub in Lübeck, she had endured a painful past marked by trauma, including sexual abuse during her childhood and giving up two of her children for adoption. In 1973, she gave birth to her daughter Anna, and the two shared a strong, loving bond.
However, on May 5, 1980, Marianne’s world was shattered. Anna had argued with her mother and decided to skip school. On her way to a friend’s house, Anna was kidnapped by 35-year-old Klaus Grabowski, a local butcher. Grabowski kept her locked in his apartment, abused her, and strangled her to death. He then stuffed Anna’s body into a box, which he later attempted to bury, only to be arrested that evening when his fiancée turned him in to the police.
Klaus Grabowski was a known sex offender with a history of abuse. He had been castrated voluntarily in 1976 while in prison for his previous crimes and had even begun hormone treatment to reverse the effects, hoping to marry his fiancée.
Despite his past, Grabowski denied having sexually abused Anna, claiming she had tried to extort him. During his trial, he even accused Anna of threatening to accuse him of sexual assault. This claim enraged Marianne, who could no longer stand to hear the man who had taken her daughter’s life smear her memory.
The Courtroom Shooting
On the third day of the trial, Marianne Bachmeier decided to take justice into her own hands. She smuggled a pistol into the courtroom and, as the proceedings continued, pulled the gun from her purse and shot Klaus Grabowski in front of everyone. Seven of the eight bullets struck him, and he died almost immediately, collapsing on the courtroom floor.
As the courtroom descended into chaos, Marianne dropped her gun and shouted, “He killed my daughter… I wanted to shoot him in the face, but I shot him in the back… I hope he’s dead.” She also referred to Grabowski as a “pig” in the moments after the shooting.
Marianne was arrested immediately, and her act of vigilantism was covered worldwide. Despite her extreme actions, she showed no remorse for what she had done. During her trial in 1982, Marianne claimed that she shot Grabowski while in a dreamlike state, visualizing her daughter’s presence in the courtroom. However, forensic experts testified that Marianne had practiced with the gun, suggesting that the act had been carefully planned.
The Trial and Conviction
Marianne’s trial and the public’s reaction were a complex and polarizing issue. She was convicted of manslaughter and unlawful possession of a firearm and sentenced to six years in prison. However, she only served three years before being released.

The case divided public opinion in Germany. Some viewed Marianne as a hero who had avenged the murder of her daughter, while others believed she had taken the law into her own hands and should have left the punishment to the courts.
The media portrayed Marianne in different lights—initially, she was seen as a grieving mother, but as journalists dug deeper into her past, the picture began to change. It was revealed that Marianne had given up two of her children for adoption and spent much of her time at the pub she ran. These details complicated her image as a perfect mother.

Aftermath and Later Life
After her release from prison, Marianne emigrated to Nigeria, where she married a German teacher. She later moved to Sicily, Italy, before returning to Lübeck, Germany, after being diagnosed with pancreatic cancer. She spent her final years living in her hometown and died on September 17, 1996, at the age of 46.

Even after her death, Marianne’s legacy as “Revenge Mom” continued to divide public opinion. Some saw her as a symbol of justice, while others believed she should have respected the legal system. In a rare interview in 1994, Marianne confessed that she had shot Grabowski to stop him from spreading lies about her daughter.
The Legacy of Marianne Bachmeier
Marianne Bachmeier’s story remains one of the most talked-about cases of vigilante justice. Her decision to take matters into her own hands remains controversial to this day. Some argue that she gave her daughter the justice she was denied by the legal system, while others claim that her actions set a dangerous precedent for taking the law into one’s own hands.

Her story speaks to the raw emotions of loss, grief, and the lengths a mother will go to for the child she lost. Though her actions were extreme, Marianne’s story serves as a painful reminder of the trauma caused by losing a loved one, especially in such a violent and unjust way.
