- Premise (Page Six, 2026-09-03): It reports KJ Biermann “has been locked up at Atlanta’s Metro Regional Youth Detention Center since his Aug. 17 arrest,” and that his attorney filed for a bond hearing in Superior Court. Source states continuous custody from Aug. 17 through Sept. 3. → Inference: Continuous detention since Aug. 17 means no release occurred on or before Sept. 1.
- Premise (Page Six, 2026-08-26): Confirms he is in custody at the Metro Regional Youth Detention Center and that a hearing was scheduled for Sept. 1. → Inference: He entered Sept. 1 still detained, and the later Sept. 3 report confirms he remained detained continuously past that date.
- Premise (FindLaw explainer, 2026-08-26): For aggravated sodomy/sexual battery in Georgia, only a superior court judge may set bail; a bond hearing must be requested in superior court. → Inference: The Sept. 3 filing for a bond hearing indicates no bond had been set prior to that date, so he was not released on bond by Sept. 1.
Conclusion: By the end of Sept. 1, 2026, KJ Biermann Jr. had not been released from secure juvenile detention.
