A 15-year-old son of former reality TV stars Kim Zolciak and Kroy Biermann was arrested last week on charges of aggravated sodomy and aggravated sexual battery, placing him in adult Superior Court under Georgia law rather than the juvenile system that typically handles cases involving minors. Kroy Jagger “KJ” Biermann Jr. remains in police custody in Fulton County as of Friday, and the case stems from an alleged assault reported months earlier at a gym.
According to TMZ, the alleged victim, a teenage classmate of Biermann Jr., told police the two went into a co-ed sauna at the gym on April 23, 2026. Per the police report cited by the outlet, the girl and her father said the incident occurred there, with the girl alleging that Biermann Jr. forced her mouth onto his penis and digitally penetrated her vagina after she told him no and he continued touching her. A police officer was dispatched to North Fulton Hospital in Roswell the following day, April 24, for a reported sexual assault, a facility that performs forensic medical evaluations in coordination with Fulton County law enforcement.
A DNA Finding Complicates the Evidence
Notably, per the police report, doctors found no evidence of male DNA in the alleged victim's mouth or vagina during the hospital examination — a detail that introduces a significant evidentiary question for prosecutors as they evaluate whether to seek a formal indictment. TMZ reports that Kim Zolciak and Kroy Biermann have not responded to the outlet's request for comment on the arrest.
Police records reviewed by TMZ show investigators attempted to contact Kroy Biermann Sr. on May 14, 2026, and ultimately spoke with him on May 18, when he said he would discuss the matter with Kim. The outlet's report indicates police then launched a broader investigation into the allegations before the arrest was made on August 17.
Why the Case Starts in Adult Court
Under Georgia Code § 15-11-560, Superior Courts hold exclusive original jurisdiction over juveniles ages 13 to 17 charged with specific designated violent felonies, including aggravated sodomy and aggravated sexual battery — a mandate that traces back to Georgia's 1994 Senate Bill 440. That statutory scheme is why Biermann Jr., despite being 15, was processed initially in adult Superior Court rather than juvenile court.
Aggravated sodomy under O.C.G.A. § 16-6-2 is classified as a serious violent felony punishable by 25 years to life in prison. Aggravated sexual battery, defined under Georgia Code § 16-6-22.2 as non-consensual penetration with a foreign object — which includes fingers — carries a mandatory minimum of 25 years in prison followed by lifetime probation, according to the Law Office of Ahmad R. Crews. Because pre-trial bond for such charges can only be granted by a Superior Court judge under § 17-6-1, bail was not available at the magistrate court level following the arrest.
Georgia law also excludes both charges from the state's First Offender Act, meaning a conviction would carry mandatory felony status without the option of a first-time-offender diversion that keeps a permanent record off the books. There is one avenue that could change the case's trajectory: under Georgia Code § 15-11-560(d), the Fulton County District Attorney holds sole pre-indictment authority to decline prosecution in Superior Court and transfer a minor's case to Juvenile Court following further investigation, per the Lynch Law Group.
A Family Already Under Scrutiny
The arrest lands amid a period of prolonged upheaval for the Zolciak-Biermann household. The couple's former 15,000-square-foot Milton, Georgia mansion — the longtime backdrop for Bravo's “Don't Be Tardy” — was foreclosed upon and sold in late 2024, then resold on June 30, 2026 for $3.695 million after asking prices had once reached $6 million, according to WSB-TV. Fulton County Magistrate Court documents from June 2025 showed deputy marshals had executed an order of ejection to physically remove Zolciak and Biermann Sr. from the residence following the foreclosure sale.
Kroy Biermann Jr. is the eldest biological child of Zolciak and Biermann Sr., who played eight NFL seasons for the Atlanta Falcons and Buffalo Bills between 2008 and 2016, recording 23.5 career sacks. The couple's divorce and financial struggles have played out publicly for years, including Biermann Sr.'s recent hike and Hoodline's earlier coverage of the family slashing the price on their Atlanta mansion amid mounting debt. Fulton County judges had previously imposed strict scheduling orders to keep the estranged couple separated even before the eviction. No further updates on Biermann Jr.'s custody status or any District Attorney decision on transfer to juvenile court had been reported as of Friday.
