German prosecutors said on Friday (local time) there is evidence of "cannibalism" in the killing of a 44-year-old man whose remains were found on the northern edge of Berlin earlier this month.
Stefan R, a maths and chemistry teacher at a secondary school, was arrested at his home on Wednesday and brought before a judge.
"The suspect had an interest in cannibalism", said Berlin prosecutors' office spokesman Martin Steltner to news agency The Associated Press. 'He searched online for the topic'.
During the investigative search, police found cutting tools, knives, saws, as well as bone fragments and traces of blood.
A 41-year-old high school teacher in Berlin, Germany, was arrested on suspicion of murder on Thursday, in connection to the discovery of human remains in the north of the city earlier this month. Proving "base motives" is necessary by German law in order to push for a fully-fledged murder conviction, a law that's a relic of the Nazi era.
By October, police searched dating platforms and search for people who could possibly be in contact with Stefan was launched.
The bones were discovered in Pankow district on November 8, with forensic analysis later showing them to be the victim's, identified as Stefan T., with police saying that further forensic investigations led them to the suspect.
In addition, the meatless bones found by pedestrians in the park raised suspicion that the flesh had been artificially removed. It is thought that he even sold the flesh of his victims at the Breslau (now Wroclaw, Poland) market as pork.
He was detained by police at his home, near where the victim was found. Danke hung himself in his jail cell two days later.
The case recalls that of Detlev Guenzel, a German ex-police officer convicted of murdering a willing victim he met on a website for cannibalism fetishists and chopping him up in an S&M chamber.
He is now serving a life sentence. Prosecutors said the victim had fantasised about being eaten but there was no evidence that the suspect actually did so.
