ATLANTA, GEORGIA — Reality television star Kim Zolciak is standing firmly behind her 15-year-old son as he faces a growing criminal case in Georgia, insisting that the allegations against him do not tell the full story.

Kroy “KJ” Biermann Jr., the son of Zolciak and former NFL player Kroy Biermann, was arrested in August and initially faced a sexual battery allegation involving a female minor.

Since then, the case has escalated significantly.

A Fulton County grand jury has indicted the teenager on seven felony counts, including aggravated child molestation, aggravated sexual battery, aggravated sodomy, sexual battery involving a child under 16 and false imprisonment. The allegations stem from an incident involving a female classmate at a Life Time fitness facility in Alpharetta, Georgia.

KJ’s defense has denied the allegations and says he intends to plead not guilty.

Kim Zolciak Publicly Defends Her Son
Following the arrest, Zolciak released a statement expressing strong support for her son and pushing back against the accusations.

She said KJ had taken a polygraph test that she believes supports his account and pointed to the reported absence of male DNA evidence in the investigation.

Her position has remained consistent: she says the public should not assume her son is guilty simply because serious allegations have been filed against him.

The defense has likewise emphasized that the accusations still have to be proven in court.

The Alleged Incident Happened at a Fitness Center
According to the allegations described in court proceedings, the case involves a female classmate and an encounter at a Life Time gym in the Atlanta-area community of Alpharetta.

Prosecutors have alleged that the encounter involved sexual conduct without the girl’s consent and that she suffered physical injuries.

During the bond hearing, prosecutors argued that the allegations were serious enough to justify keeping KJ in custody and cited what they described as documented injuries to the alleged victim.

The defense has disputed the prosecution’s characterization of what happened.

KJ’s lawyer has argued that the evidence is not as straightforward as prosecutors have suggested and has questioned the interpretation of parts of the investigation.

Grand Jury Indictment Changes the Case
The biggest development since the initial arrest came when prosecutors secured a grand jury indictment.

Rather than facing only the original allegation, KJ now faces seven felony charges.

The indictment includes accusations involving aggravated sexual conduct, sexual battery, child molestation and false imprisonment.

That means the case has moved into a more serious phase of the criminal process.

KJ’s attorney, Jason Sheffield, has said the teenager should be treated according to his age and has filed a request seeking to have the case handled in juvenile court rather than adult criminal court.

At the time of the alleged incident, KJ was 14.

Prosecutors Raised Another Set of Allegations
During a recent bond proceeding, prosecutors made additional allegations that were not part of the original public account of the case.

According to reporting on the hearing, investigators allegedly found videos on KJ’s phone that prosecutors said showed sexual activity involving an underage family member.

Prosecutors characterized the alleged behavior as particularly concerning and said it raised questions about whether this was an isolated incident.

The defense has strongly disputed the way the earlier allegations have been characterized.

KJ’s attorney argued that the prior matter involved inappropriate behavior between young teenagers and said prosecutors’ description gave a misleading impression of what actually happened.

Those claims are part of the ongoing legal dispute and have not been established as facts by a criminal conviction.

KJ Was Already Under Court Supervision
Another important element revealed during the proceedings is that KJ had previously been under court supervision dating back to October 2025 in connection with an earlier sexual-battery allegation involving a person under 16.

Prosecutors cited that history while arguing against releasing him.

The defense, however, has characterized the earlier case differently and has argued that it should not be used to portray the teenager as someone who has already been found guilty of serious sexual crimes.

The dispute over that previous matter is likely to become important as lawyers argue over how KJ’s current case should be handled.

Judge Grants $200,000 Bond
After the recent hearing, Judge Melynee Leftridge granted KJ a $200,000 bond.

The conditions are strict.

KJ is required to remain at his mother’s residence, wear electronic monitoring and attend school remotely. He is also prohibited from having contact with the alleged victim and, according to reports from the hearing, must have no contact with minors.

The restrictions reflect the seriousness of the allegations while allowing the teenager to remain outside detention as the case proceeds.

Kim Zolciak and Kroy Biermann both appeared in court in support of their son. Reports from the hearing described both parents as visibly emotional, although they arrived separately.

Defense Wants the Case Moved to Juvenile Court
One of the next major legal battles will be over whether KJ should be prosecuted as a juvenile or continue facing the case under the adult system.

His attorney has asked the court to transfer the matter to juvenile court, arguing that KJ was only 14 when the alleged conduct occurred and that his age and development must be considered.

The outcome could have enormous consequences.

An adult prosecution could expose the teenager to dramatically more severe consequences than a juvenile proceeding, making the jurisdictional dispute one of the most important issues in the case.

Zolciak Says the Allegations Have Taken an Emotional Toll
The legal battle comes at a particularly difficult time for the Biermann family.

Kim Zolciak and Kroy Biermann have been involved in a highly publicized and contentious divorce, while continuing to deal with custody and financial disputes involving their children.

The criminal case against KJ has added another layer of pressure to an already complicated family situation.

Zolciak has continued to defend her son publicly, while KJ’s legal team says the teenager has been deeply affected by the case and by his time in detention.

What Happens Next?
KJ’s case is scheduled to move forward with an arraignment on October 14, 2026, according to the latest reporting.

His attorneys have indicated that he plans to plead not guilty.

They are also seeking to have the case transferred to juvenile court and have asked that proceedings involving minors be handled with additional privacy protections.

For now, KJ is out of detention under strict court supervision.

The allegations remain unproven.

Latest Status — September 12, 2026
As of September 12, Kroy “KJ” Biermann Jr. remains presumed innocent. He has been indicted on seven felony counts, has been granted a $200,000 bond with strict conditions and is expected to appear for arraignment on October 14. His defense continues to deny the allegations and is seeking a juvenile-court transfer.

Kim Zolciak continues to stand behind her son, while prosecutors maintain that the evidence and allegations justify the serious charges filed against him.

The next major question is no longer simply whether KJ will remain in custody — it is whether the case will proceed in adult court or be transferred to the juvenile system.

All allegations described in this article are accusations. KJ Biermann has not been convicted of any crime.
