What happened
Teenagers Karin Gattiker and Brigitte Meier disappeared in 1982 and were later found dead in a cave in northern Switzerland.
The investigation
Police pursued numerous leads and suspects, but the age of the evidence and lack of a decisive forensic link prevented a prosecution.
What the courts or investigators concluded
No one has been convicted and the killings remain an enduring Swiss cold case.
Why the case remains significant
The case continues to attract attention because two young victims vanished together and the unusual recovery location created a powerful mystery without producing a provable offender.
