According to two police officers at the scene, Marianne also called Grabowski a “pig” after she opened fire.

She was arrested by police in the courtroom and initially charged with murder. During her trial in 1982, Marianne claimed that she shot Grabowski in a dream state after visualizing her daughter in court.

But according to experts who testified at the trial, Marianne’s act required special practice with the gun, indicating that she had planned and prepared everything ahead of the shooting.

The mother was also examined by doctors and asked if she could give them a handwriting sample. In response, Marianne wrote: “I did it for you, Anna.” The sample was also decorated with seven hearts – which many interpreted as a tribute to each year of Anna’s life.

If convicted, Marianne was to face a lifetime of imprisonment.
