Question juridique clé
Whether the continuation of pretrial detention was justified by collusion risk.
Solution extraite
No concrete indications of collusion risk existed; the theoretical possibility of witness influence was insufficient, especially after the investigation was largely complete.
Motifs extraits
The investigation was far advanced and essential evidence had been taken. The victims and key witnesses had long lacked personal ties to the defendant, and there were no concrete signs of attempted influence or pressure. Higher scrutiny applies once the investigation is essentially closed.
