Kernrechtsfrage
Whether the prosecutor established a sufficient urgent suspicion for surveillance under Art. 269 StPO.
Extrahierter Entscheid
Yes. The suspicion had been concretized and strengthened over several months through earlier custody decisions and investigation results.
Extrahierte Begründung
A fresh, separately intensified suspicion is not required for every coercive measure. The file showed concrete indications linking the accused to the homicide, and the earlier judicial confirmations of suspicion were recent.
