Overview
- Stockholm chief prosecutor Lennart Guné announced in December 2025 that the 2020 conclusion naming Stig Engström as the killer is disavowed and that no persuasive evidence supports it.
- In 2020 prosecutor Krister Petersson had identified Engström, a Skandia employee who died in 2000, and declared the investigation closed because the suspect was deceased.
- Recently declassified records include a 1988 memorandum by counterintelligence head Tore Forsberg describing an unidentified operation in central Stockholm the night of the shooting, code-named “Così fan tutte,” without yielding a prosecutable suspect.
- Testimony cited in the released files describes plainclothes individuals using handheld radios near Sveavägen and the Tunnelgatan escape route that night, though any intelligence role remains unproven.
- Early police missteps—an unsecured crime scene, no checkpoints and no train stoppages—helped thwart the inquiry, which over decades cost millions, involved about 10,000 interviews and produced 134 confessions judged not credible.
