What happened
Rabbi Abraham Grünbaum was shot dead in Zurich in 2001 while visiting Switzerland.
The investigation
Swiss investigators examined possible motives ranging from robbery to extremist violence and followed leads in several countries, but no prosecution established who killed him.
What the courts or investigators concluded
The murder remains unsolved.
Why the case remains significant
The case has retained particular significance because of concern that antisemitic ideology may have played a role, while investigators have had to avoid presenting an unproved motive as fact.
