Overview
- Dagmar Knops, a 22-year-old student, vanished on the short walk home from the Lichtblick bar in Kempen on the night of March 28–29, 1988 and no body has ever been found.
- Police and the Staatsanwaltschaft Krefeld have reopened the investigation in 2026 and will present the case on ZDF’s Aktenzeichen XY on Wednesday, November 4, to appeal for witness information.
- Investigators are asking specifically for people who sat on a bench near the bar that night and they are urging the authors of anonymous letters from 2005 and 2008 to come forward.
- Distinctive personal items Knops wore that night — an Avirex 'Air Force USA' jacket, a copper engraved bracelet, a silver chain with a key fob, and her wallet — remain missing and are considered possible leads.
- A combined €10,000 reward has been offered for decisive information and police say even small or seemingly unimportant memories could help move a nearly four-decade-old inquiry toward an arrest.
