A cold case from 2014 is still on the mind of the head of the cantonal police, Senat Sakic says: "It is the only unsolved homicide in our canton."
The mysterious case is now at the center of the cult show "Aktenzeichen XY ... Unsolved" with Rudi Cerne.
What happened in 2014? On the night of September 19-20, 2014, a prostitute disappears from the streets of Lucerne. On Sunday morning, a walker discovers her body in Lake Lucerne near Stans NW. It soon becomes known: The 36-year-old Bulgarian woman had been murdered. Despite intensive investigations and various leads, the Nidwalden cantonal police are unable to identify the perpetrator and bring him to justice.
The case remains unsolved and becomes a so-called "cold case".
Now, more than ten years after the murder, Sakic wants to do everything he can to solve the case after all. He sets up a special commission and turns to the TV show "Aktenzeichen XY ... Ungelöst".
