“Revenge mom” shot her child’s murder in the middle of his trial

The loss of a child is widely recognized as the ultimate tragedy—the singular, devastating experience that represents a parent’s worst nightmare. For Marianne Bachmeier, a struggling single mother running a pub in Lübeck, Northern Germany, this nightmare became a permanent reality on May 5, 1980.

A Life Defined by Trauma

Marianne’s path to that fateful day was paved with hardship. Her upbringing was marred by the dark shadow of her father’s past as a member of the Waffen-SS, and her own youth was punctuated by a series of horrific sexual assaults. These early traumas shaped a difficult adolescence; at 16, she became pregnant and, unable to provide for the infant, gave the child up for adoption. Two years later, history repeated itself, and she surrendered a second baby to an adoption agency.

It wasn’t until 1973 that Marianne gave birth to her third child, Anna. This time, Marianne chose to raise her daughter alone. By all accounts, Anna grew into a “happy, open-minded child.” But the stability they had built was destined to be shattered.

The Disappearance of Anna

In May 1980, following a routine mother-daughter argument, seven-year-old Anna skipped school to head to a friend’s house. She never arrived. She was intercepted by Klaus Grabowski, a 35-year-old local butcher with a dark history.

Grabowski held Anna captive in his apartment for hours, subjecting her to abuse before finally strangling her to death. In a cold attempt to hide his crime, he packed her small body into a box and stashed it near a canal bank. He was arrested that evening at his favorite pub after his own fiancée, suspicious of his actions, alerted the authorities.

The revelation of Grabowski’s past ignited public fury. He was a convicted sex offender who had previously served time for assaulting two young girls. During a 1976 prison stint, he had undergone voluntary castration, only to begin hormone treatments two years later to reverse the procedure so he could pursue a relationship with his fiancée.

The Trial That Broke a Mother

While Grabowski confessed to the murder, he adamantly denied sexual abuse. Instead, he employed a defense that many found repulsive: he claimed the seven-year-old had attempted to seduce and blackmail him, demanding money under the threat of telling her mother he had touched her.

While the court remained skeptical of his claims, the smear campaign against her deceased daughter pushed Marianne into a state of powerless rage. On March 6, 1981—the third day of the trial—she decided the legal system would not be the final word.
