October 22, 1930 - John Ingvar Lövgren
Operating in the Stockholm region across nearly a decade, Lövgren represents one of Sweden's earlier documented serial homicide cases, his crimes unfolding in an era when such patterns were rarely recognized or systematically investigated. The combination of sexual violence and multiple killings, followed by eventual confession, placed him within the psychiatric detention system rather than conventional incarceration — a reflection of mid-twentieth-century Scandinavian approaches to criminal responsibility.
From Wikipedia
John Ingvar Lövgren (22 October 1930 – 9 February 2002), later renamed John Ingvar Andersson, was a Swedish serial killer and rapist who confessed to four murders committed between 1958 and 1963 in the Stockholm region. Lövgren was convicted and sentenced to closed psychiatric treatment at Salberga prison. He went under the name Flickmördaren (lit. 'The Girl Killer'), because his last two victims were young girls. He was, at the time of his death in 2002, no longer in treatment due to poor health caused by terminal cancer. He was buried at Sala cemetery.
