Aktenzeichen XY… Ungelöst: Solving Crimes on German Television Since 1967
Mainz, 14 January 2026 – Aktenzeichen XY… Ungelöst, the longest-running crime investigation programme on German television, has been assisting police in solving unsolved cases for nearly six decades. Hosted by Rudi Cerne, the show combines dramatic reconstructions with public appeals for information, often leading to breakthroughs in cold cases.
History and Origins
The programme began in 1967, inspired by its creator Eduard Zimmermann’s experiences with fraud prevention shows. Initially produced in cooperation with Austrian and Swiss broadcasters, it quickly became a staple on ZDF. Zimmermann moderated until 1987, after which Norbert Gastell and others took over before Rudi Cerne assumed the role in 2002. The show has aired over 1,185 episodes, focusing on serious crimes like murder, theft, and organised crime.
Format and Impact
Each episode features three to six unsolved cases, reconstructed in short films lasting about ten minutes. Viewers can provide tips via telephone or online, with the editorial team reporting that around 40 per cent of cases are solved. Special editions include “Aktenzeichen XY… gelöst” for resolved cases, “update” for new developments, and “Cold Cases” for long-standing mysteries. The programme has inspired international adaptations, such as Crimewatch in the UK and America’s Most Wanted in the US.
