On March 6, 1981, Marianne Bachmeier walked into a courtroom in Lübeck, Germany with purpose in every step.
Moments later, she pulled a loaded pistol from her purse and opened fire on 35‑year‑old sex offender Klaus Grabowski.
He had been accused of kidnapping, abusing, and murdering Marianne’s 7‑year‑old daughter, Anna Bachmeier.
Within seconds, Grabowski took his final breath on the courtroom floor — seven of Marianne’s bullets had struck him. She was immediately arrested, showing no trace of remorse. Forty years later, “Revenge mom” remains a symbol that still divides a nation.
The loss of a child is often described as the worst pain a parent can endure.
On May 5, 1980, Marianne’s life changed forever. In the early ’80s, she was a struggling single mother running a pub in Lübeck, northern Germany. Her own youth had been marked by trauma: her father had been a member of the Waffen‑SS, and she had been raped multiple times by different men.
At 16, she became pregnant and gave the baby up for adoption. At 18, she became pregnant again and made the same heartbreaking decision.
In 1973, she gave birth to her third child, Anna — and this time, she raised her daughter alone.
Anna was described as a “happy, open‑minded child,” but tragedy struck in May 1980. After an argument with her mother, Anna skipped school and headed to a friend’s house. On the way, she was kidnapped by 35‑year‑old butcher Klaus Grabowski.
Grabowski held Anna in his apartment for hours, abused her, and eventually strangled her. He hid her body in a box near a canal.
He was arrested later that evening after his fiancée reported him to police. Grabowski was already a convicted sex offender who had previously assaulted two girls. During a prior prison sentence, he had voluntarily undergone castration, then later reversed it with hormone treatments.
Grabowski confessed to killing Anna but denied sexually abusing her. In court, he went even further — claiming Anna had tried to seduce and extort him.
He blamed his victim for his crime, insisting he killed her only because she threatened to accuse him of inappropriate touching unless he paid her.
The court did not believe him.
But his disturbing claims pushed Marianne into a state of rage, grief, and helplessness. On the third day of the trial, she decided to act.
Somehow, she managed to smuggle a gun past security. Shortly after entering the courtroom, she pulled the weapon from her handbag and fired. Seven of eight bullets hit their target. Grabowski died instantly.
After the shooting, Marianne dropped the Beretta M1934 and said:
“He killed my daughter… I wanted to shoot him in the face, but I shot him in the back… I hope he’s dead.”
Witnesses said she also called him a “pig.”
She was arrested on the spot and initially charged with murder. During her 1982 trial, she claimed she acted in a dream‑like state after imagining her daughter in the courtroom.
Experts disagreed, testifying that her accuracy suggested practice and planning. When asked for a handwriting sample, Marianne wrote: “I did it for you, Anna,” decorating the note with seven hearts — interpreted as one for each year of Anna’s life.
If convicted, she faced life in prison.
Her act of vigilante justice drew massive media attention worldwide. Many saw her as a grieving mother who did what the justice system could not. Early coverage portrayed her as a saint — until journalists began digging into her past, including the children she had given up for adoption and her time spent working in a bar.
In 1983, Marianne was convicted of premeditated manslaughter and unlawful possession of a firearm. She received a six‑year sentence but was released after three.
Public opinion was sharply divided. A survey by the Allensbach Institute showed 28% thought her sentence was fair, 27% thought it was too harsh, and 25% believed it was too lenient.
After her release, Marianne moved to Nigeria and married a German teacher. She later divorced and relocated to Sicily. Eventually, she was diagnosed with pancreatic cancer and returned to Lübeck.
Her act of revenge remained a topic of national debate throughout the 1990s.
In a 1994 radio interview, she said:
“I think there is a very big difference if I kill a little girl because I’m afraid I then have to go to prison for my life… and then also the ‘how’…”
In a 1995 interview with Das Erste, she admitted she had shot Grabowski after careful consideration, wanting to stop him from spreading more lies about Anna.
On September 17, 1996, Marianne died in a Lübeck hospital. She had hoped to return to Sicily but never made it. She was buried beside her daughter.
Marianne’s case remains one of the most debated examples of vigilante justice. Many believe she delivered the punishment Grabowski deserved. Others argue she should have left justice to the courts.
