Dokument inifrån: Fallet Kevin

40 years ago, a woman was found dismembered under a highway in Stockholm. It was the beginning of what would become Sweden's strangest and most controversial legal process: the Catrine da Costa case. The two doctors Teet Härm and Thomas Allgén were identified as guilty of the dismemberment. But how did the legal system actually come to the conclusion that they were guilty?

Margit Norell - the woman behind the serial killer that was not there. She was a psychotherapist at Säters psychiatric clinic and supervised the psychologists and therapists in the 1990s treatment of Thomas Quick. The treatment method, based on object relations theory, focused on the development of repressed childhood memories with psychotherapy. In the case Thomas Quick argued that abuse in childhood meant that he started murdering people in adulthood. Whereupon Quick admitted one murder after another, and finally was convicted of eight murders.
