In 1905, Haarmann began to maintain gay contacts with young people at Hanover's main train station. It was also at this point that his criminal career as a thief, burglar and fence was started. Haarmann lived in Hanover's red light district, where he met Hans Grans in 1919. Both had a sexual relationship. Grans soon moved in with Haarmann and gradually brought home runaway boys. These raped and killed her. Haarmann then sold her clothing as a used clothing retailer.
Haarmann has long been suspected by the police of having committed several murders of boys. He was arrested in June 1924. With the alleged use of police force, Fritz Haarmann is said to have admitted several murders on July 1, 1924, which he revoked the following day. On July 5, 1924, at the insistence of the police in Hanover, the water level of the line was lowered, in the river bed of which about 300 human bones were subsequently recovered. 22 victims of Haarmann could be assigned to the find.
In December 1924 the trial of Fritz Haarman was committed. The event aroused widespread media interest, which Haarmann visibly enjoyed. One of the reasons for the popularity abroad was the fact that Fritz Haarmann al Spitzerl worked for the police.
The trial lasted from December 4 to 19, 1924. Haarmann was charged with 27 murders. The butcher of Hanover was executed on April 15, 1925.
