Kim Zolciak’s son faces sex claim with under‑12 relative—lawyer denies

Kim Zolciak’s 15‑year‑old son, Kroy “KJ” Biermann Jr., was in the spotlight again Friday when his attorney released a statement that both clarified and contested new allegations. , prosecutors are pursuing charges that the teen allegedly engaged in sexual activity with an under‑12 family member, based on video evidence found on KJ’s phone.

The judge set a $200,000 bond and ordered an ankle monitor while KJ remains in juvenile detention awaiting his next court date.

The allegations surfaced during a bond hearing on September 11, the same day reported that prosecutors had discovered footage of “multiple encounters” where KJ allegedly used “predatory [and] derogatory” language toward the victim. No arrest has yet been made for the new claims, but prosecutors said they plan to press charges.

The case is already mired in previous legal proceedings that began with an August arrest for aggravated sexual assault and battery at a gym.

In the wake of the hearing, Zolciak and her daughter Brielle Biermann were seen outside the courthouse, though neither spoke publicly about the situation. The family’s children—KJ, his 14‑year‑old brother Kash, twins Kaia and Kane (12), and adopted sisters Brielle (29) and Ariana (24)—remain under various legal and social constraints.

KJ’s lawyer has positioned the new evidence as “more ridiculous, raunchy behavior” rather than illegal conduct.

## Background & Context

KJ was arrested in August in Alpharetta, Georgia, after an alleged incident with another underage victim at a gym. The arrest was for aggravated sexual assault and aggravated battery, and he was immediately remanded to Atlanta’s Regional Youth Detention Center, where he stayed until his bond hearing.

A week later, prosecutors indicted him on five counts: aggravated child molestation, aggravated sexual battery, aggravated sodomy, false imprisonment, and three counts of sexual battery against a child under 16. He has not been arrested for the remaining charges in the indictment.

On September 8, KJ’s attorney filed a motion to transfer the case to juvenile court, hoping to keep his client from being tried as an adult.

The lawyer said that “it is difficult to comprehend that a 14‑ or 15‑year‑old child can be held in detention for a month or longer simply waiting for a bond hearing,” and noted that the detention was a direct consequence of the detective’s decision to arrest him on charges of this magnitude.

The judge’s decision on bond set KJ at $200,000 and requires an ankle monitor, but allowed him temporary release pending further proceedings.

The new allegations involve alleged sexual activity with a family member under the age of 12, based on video found on KJ’s phone. Prosecutors claim that the footage shows “multiple encounters” in which KJ used “predatory [and] derogatory” language toward the victim, and they intend to press charges after the bond hearing.

No other details about the victim or the identity of the relative have been released.

## What People Are Saying

KJ’s lawyer,

Jason Sheffield, said in a statement to that “the characterizations made in court regarding the prior juvenile matter involving KJ Biermann grossly misrepresent both the facts and the ultimate resolution of that case.” He also added, “the matter arose from inappropriate, crude behavior involving two middle‑schoolers.” Sheffield described the video evidence as “more ridiculous, raunchy behavior” rather than illegal conduct, noting that it was a boundary‑crossing but not a statutory violation.

Sheffield further argued that any suggestion otherwise is inaccurate and creates a “materially misleading impression” of how the juvenile matter was ultimately resolved. In a statement to Us, he added, “First and foremost, this is not the kind of information that should be for public dissemination.

These are juveniles.” He claimed that KJ “is 100 percent innocent and tried to present evidence to the arresting officer, including a passed polygraph by a notable and respected sex offender polygrapher.”

In contrast, the police report cited by prosecutors indicated that investigators found no male DNA on or inside the areas the alleged victim claimed she was assaulted. The officer’s report noted that the Georgia Bureau of Investigation found no male DNA on or inside the areas the alleged victim claimed she was assaulted.

Sheffield contended that had the officer sat down with him, KJ would not have been arrested.

## What Happens Next

KJ’s upcoming October arraignment will determine whether the new charges are formally filed and what legal path his case will take. The motion filed on September 8 to transfer his case to juvenile court remains pending, and its outcome could alter the level of scrutiny his case receives.

Meanwhile, KJ will continue to be monitored by an ankle bracelet as part of his bond conditions until the next court appearance.

The judge’s decision to grant bond after a month in detention was seen as a significant relief for the family, but prosecutors have indicated they plan to press charges once the evidence is fully reviewed. The case remains in flux, with no final verdict on the new allegations yet reached.

As the court schedule approaches, all eyes will remain on the courtroom and the family’s next steps.
