After A two day search for the missing child, the torso of the 9 year old Lucie Berlin was pulled from the river Spree, Germany June 11th. Her head and limbs had been cut off and she had been raped.
Police Inquiries at the slum tennement where she lived focused on the flat of prostitute Johanna Liebestruth, immediatly above the Berlin family. It was common gossip the Theodore Berger had been living off the prostitutes earnings and had finally concented to marry her. The lady explained why. She spend 3 days prior to the discovery of Lucies body in jail, and returned to find her suitcase missing. Berger admitted to entertaining another prostitue while she was gone and gave that woman her suitcase. He agreed to marry Liebestruth as compensation.
Berger denied all this, especially after the badly bloodstained suitcase was discovered in a canal. The childs head and legs were found in the same canal.
At Bergers trial it transpired that the little girl had come up to Liebestruth's flat while Berger was there and thoughtlessly stood on her head . The sight of her legs so imflammed the brute, who tried to assault her; strangeling her as she struggled. He then raped the girl and dismembered the body taking the parts to the water in the suitcase.

In 1900, a series of experiments by Paul Uhlenhuth led to a serum that reacted to the presence of human blood, but not to the blood of animals. The crime investigator would dissolve blood evidence in salt water, and then add the solution to the special serum. Human blood darkened the serum via the precipitation of a protein. The 1904 slaying of nine-year-old Lucie Berlin was the first murder case solved by the amazing new blood detection method.
