Key legal question
Whether the continuation of pre-trial detention was lawful despite the applicant's challenge to collusion risk.
Extracted holding
The detention was lawful because concrete indications showed a real risk that she could influence witnesses and otherwise impair fact-finding.
Extracted reasoning
Collusion under § 58 Abs. 1 Ziff. 2 StPO/ZH requires more than a theoretical possibility. Here, the court relied on the applicant's prior conduct, the seriousness of the allegations, her relationships with key persons, and the ongoing danger to the truth-finding process even after the investigation stage.
