Overview
- Katrin Konert, then 15, vanished from the town centre of Bergen an der Dumme on January 1, 2001 and police treat the case as a suspected homicide.
- The case was featured on ZDF’s Aktenzeichen XY on June 3, 2026 with investigator Annegret Dau‑Rödel appearing live to urge viewers and local witnesses to come forward.
- Police are urgently seeking an anonymous 2018 tipster whose message partially matched verifiable facts but who stopped responding to follow‑up contact through the BKMS portal.
- Authorities have reissued an anonymous questionnaire, published a Kripo Lüchow contact number, and are offering a €10,000 reward for information that leads to clarification.
- After the broadcast police reported several new leads under review but said none was an immediate breakthrough as investigators continue targeted local inquiries and witness re‑interviews.
