The teenage son of "Real Housewives of Atlanta" alum Kim Zolciak was taken into custody on charges of aggravated sodomy and aggravated sexual battery, allegations the family calls "reckless" and categorically denies.
Kroy "KJ" Biermann Jr., 15, was arrested by Alpharetta, Georgia, police and is being held without bond after a 15-year-old female classmate accused him of sexually assaulting her in a changing area at a Life Time fitness center in Alpharetta on April 23, Page Six reported. A hearing in Fulton County Juvenile Court is scheduled for September 1.
The charges, aggravated sodomy, which under Georgia law involves a non-consensual sexual act, and aggravated sexual battery, carry severe consequences even in the juvenile system. KJ is the son of Zolciak, 47, and retired NFL player Kroy Biermann, 40. The couple married in 2011 and have been in a contentious divorce since Zolciak filed in 2023.
Fulton County Juvenile Court papers obtained by Page Six lay out the alleged victim's account. She described herself as "KJ's girlfriend's best friend." She claimed KJ forced himself on her in a co-ed sauna at the gym despite her repeatedly saying "no," attempted multiple times to pull down her pants for sexual intercourse, forced oral sex, and digitally penetrated her.
When she "finally managed to get away from him," the court papers state, "he pulled up his pants and left."
One detail flagged in the documents: KJ allegedly did not scan into the gym on the day of the alleged assault, but security camera footage from the facility showed him present. The documents do not explain the discrepancy.
The alleged victim did not tell anyone about the incident that night. She went to school the next day, April 24, and ran into KJ's girlfriend there. She then left school for a nearby Starbucks, where she experienced a panic attack and contacted her family. She was taken to North Fulton Hospital for a medical examination that same day.
The April 24 examination at North Fulton Hospital showed no evidence of male DNA in the alleged victim's mouth or vagina, according to the police report. That finding is central to the defense's case, and to the broader question of what physical evidence, if any, supports the charges.
Police did not make their first attempt to contact Kroy Biermann until May 14, more than three weeks after the alleged assault. They spoke with him four days later, on May 18. Biermann told officers he would discuss with Zolciak whether their son could speak to police. The specific law enforcement agency handling the investigation was not identified in the court filings.
KJ was ultimately taken into custody on a Monday, though the exact arrest date was not specified in the court records. The New York Post reported that Alpharetta police made the arrest.
Zolciak issued a detailed exclusive statement to Page Six defending her son and raising questions about the accuser's credibility. She said KJ voluntarily took a polygraph examination and passed. She also said a separate examination found no DNA belonging to KJ, though it remains unclear whether that refers to the same April 24 hospital exam documented in the police report or a different test.
Zolciak went further, claiming the alleged victim "has made similar allegations involving two other people." She did not name those individuals, and no details about those alleged prior claims, whether they were formally reported or investigated, appeared in the court filings.
In her statement, Zolciak struck a tone that was both combative and measured:
"The allegations being made against my son are nothing short of reckless and deeply troubling. He categorically denies ever being involved with this woman or engaging in the conduct she has alleged."
She added:
"Every legitimate allegation deserves to be taken seriously and investigated based on the facts and evidence. At the same time, no one should be publicly condemned based solely on an accusation."
KJ's attorney, Jason Sheffield, offered an even more forceful defense. "He is not only presumed innocent, but is in fact, innocent," Sheffield said.
Page Six also reached out to KJ's lawyer and Kroy Biermann's representative for comment. No responses were noted in the reporting.
The arrest lands on a family already under public strain. Zolciak and Biermann's divorce proceedings since 2023 have been widely covered. The couple shares four children: KJ, Kash (14), and 12-year-old twins Kaia and Kane. Zolciak also has two older daughters from a previous relationship, Brielle (29) and Arielle (24). KJ appeared on the family's Bravo spinoff "Don't Be Tardy."
On May 31, weeks after police first contacted Biermann about the allegations, Zolciak posted an Instagram birthday tribute to KJ. "You give the biggest, best hugs, and I am so proud of the young man you have become," she wrote. "No matter how old you get, you will always be my baby, my greatest blessing, and one of my proudest accomplishments."
Whether she knew about the investigation at that point is not clear from the available record. Biermann had spoken with police on May 18, thirteen days before the post.
Several significant gaps remain. The polygraph Zolciak cited, who administered it, under what conditions, and what specific questions were asked, is unverified beyond her own statement. Polygraph results are generally inadmissible in court. The "similar allegations involving two other people" that Zolciak referenced have not been corroborated by any official source.
The security camera footage placing KJ at the gym despite no scan-in record raises its own questions, for both sides. It confirms his presence at the facility, but the lack of a scan-in could suggest he entered through irregular means, or simply that the system failed to log him.
The case is proceeding in juvenile court. Whether additional charges could follow, or whether the matter could be transferred to adult proceedings, has not been addressed in any filing made public so far. TMZ first reported the arrest.
KJ Biermann is 15. The alleged victim is 15. The charges are grave. The physical evidence documented so far does not appear to corroborate the allegations, but the legal process is just beginning. A court date is set. The facts will either hold up or they won't, and a system that takes accusations seriously owes the same rigor to the defense.
