[The murder at Grünerløkken--a centenary].

In December 1898, a five year old boy was found murdered and sexually abused at Grünerløkka in Oslo. The crime was reported to the police by a 19 year old boy, who soon after was detained and charged with the misdeed. In spring 1899 he was found guilty and sentenced to life imprisonment with hard labour. This article is based on a long and detailed forensic medical and psychiatric report from the investigation and trial, published in this Journal in 1899, and on the Oslo press coverage of the crime. It shows that much has changed during these 100 years regarding both the privacy of the victim, the accused and their families, and factors paid attention to in the psychiatric assessment of the accused.
