Overview
- Investigators reopened the file in late October 2026 and publicly stated they now treat Dagmar Knops’s disappearance as a likely killing.
- Knops vanished after leaving the Lichtblick pub on 28 March 1988, and she never reached her parents’ home about 350 meters away.
- Police are seeking the author or authors of two anonymous letters from 2005 and 2008 that named alleged burial sites where searches turned up nothing.
- The Staatsanwaltschaft Krefeld has offered a €5,000 reward and the case will be presented on ZDF’s Aktenzeichen XY on 4 November 2026 to solicit new tips.
- Investigators stress that even small or faded memories could be crucial after decades and have published a dedicated hotline and email for the Mordkommission KNOPS to collect leads.
