Key legal question
Whether pretrial detention had to be lifted because flight risk was not sufficiently established and substitute measures were adequate.
Extracted holding
The detention was lawful because concrete circumstances showed a significant flight risk and substitute measures would not sufficiently neutralize it.
Extracted reasoning
The accused faced a severe penalty for a serious violent offence, had foreign ties and limited Swiss-rooted connections, and his social/family links suggested an actual risk of absconding. The cantonal authorities could reassess that risk over time.
