Prosecutors wanted to discover why.Grabowskis attorneys centered their defense on his medical history. They argued that hormone therapy administered after his voluntary castration had impaired his judgment. If the treatment had destabilized him, they suggested, then the crime was not solely the act of a calculating predator but of a man who was chemically unbalanced.The argument became a national debate in West Germany.

Marianne Bachmeier was arrested at the scene and later convicted of premeditated manslaughter.Her actions split public opinion across Germany and around the world.
