KJ Biermann, 15, Arrested on Aggravated Sexual Assault Charges in Georgia

On Friday, August 21, 2026, widespread U.S. media coverage brought public attention to the arrest of Kroy “KJ” Biermann Jr., the 15-year-old son of reality-TV star Kim Zolciak and former NFL linebacker Kroy Biermann. Court records show the teen was taken into custody in Alpharetta, Georgia, on Monday, August 17, and is being held without bond on charges of aggravated sodomy and aggravated sexual battery stemming from an alleged assault on a female classmate at a gym in April. The same day reports spread, Zolciak issued a public statement denying the allegations.

Editor’s note: This article draws on Fulton County juvenile court records, Alpharetta police incident reports cited by Atlanta News First (WTOC), and reporting from Us Weekly and other U.S. outlets published August 21, 2026. The alleged victim is a minor and is not identified here. Charges are allegations; no conviction has been entered.

Who is KJ Biermann?

KJ Biermann Jr. is the eldest son Zolciak shares with Kroy Biermann. The couple married in 2011, the year KJ was born, after meeting on The Real Housewives of Atlanta. They later had sons Kash and twins Kaia and Kane. Kroy Biermann also adopted Zolciak’s two older daughters, Brielle and Ariana, from a previous relationship.

The family starred for years on Bravo’s Don’t Be Tardy. In recent years Zolciak and Biermann have been in a prolonged, highly public divorce and custody dispute. In May 2026, a judge granted Kroy Biermann primary physical custody of the couple’s youngest children — a ruling that drew its own headlines before the August arrest.

What police and court records allege

According to incident reports and court filings described in multiple outlets:

Detail	What records say
Alleged date	April 23, 2026
Location	A Life Time Fitness center in Alpharetta
Setting	A co-ed sauna and family locker-room area
Victim	A 15-year-old female classmate (not publicly named)
Hospital visit	Alpharetta police were dispatched to North Fulton Hospital on April 24 after a sexual-assault report; the teen underwent a sexual-assault examination
Investigation	Detectives interviewed witnesses, reviewed security footage, and spoke with Kroy Biermann Sr. in May after earlier attempts to reach the family

Outlets including Us Weekly, citing a police report, say the alleged victim told investigators she was a friend of KJ’s girlfriend and that she repeatedly said no during the encounter. Security video cited in reporting placed KJ at the gym, though investigators noted he had not scanned in with his membership on the day in question, according to accounts of the report.

Medical records referenced in the police file indicated that examiners did not find male DNA in certain samples, Us Weekly reported. Zolciak later cited the absence of DNA evidence in her public denial.

Arrest, detention, and next court date

Fulton County juvenile court records show KJ was arrested August 17, 2026, arraigned before Magistrate Court Judge Cassandra Kirk, and denied bond. He is held at the Metro Regional Youth Detention Center.

Attorney Jason Sheffield is representing the teen, according to Atlanta News First. A preliminary hearing is scheduled for September 8, 2026, per court records cited by Us Weekly.

Because the defendant is a juvenile, many procedural details — including potential sealing of records if the case is resolved in juvenile court — may remain limited under Georgia law.

Kim Zolciak’s public response

As national outlets published the arrest story on August 21, Zolciak addressed the case publicly. Reporting characterized her statement as a forceful denial of the allegations against her son, emphasizing that he maintains his innocence and pointing to the reported lack of DNA findings.

Kroy Biermann had not issued a public statement about the arrest as of the initial wave of reporting on August 21, according to Us Weekly and other outlets. Police records cited in reporting show an officer spoke with Biermann in May during the investigation.

Family background and legal context

The case sits at the intersection of several factors that amplify coverage:

• Celebrity family: Zolciak and Biermann have been reality-TV fixtures for more than a decade.
• Ongoing custody fight: The May 2026 custody ruling already kept the family in the news.
• Serious felony charges: Aggravated sodomy and aggravated sexual battery are among Georgia’s most severe sex-crime allegations.
• Juvenile defendant: Legal and ethical constraints on identifying minors shape how media report the case.

Georgia treats many sex offenses involving minors as felonies with significant potential penalties, though juvenile proceedings often differ from adult criminal courts in sentencing and public disclosure.

What happens next

The September preliminary hearing will determine whether prosecutors have sufficient evidence to proceed. Either side may file motions on evidence admissibility, witness testimony, and bond — though bond was not set at arraignment.

If the case remains in juvenile court, proceedings are typically closed to the public. If prosecutors seek to charge KJ as an adult — a decision that would require a separate judicial process in Georgia — the case could shift to adult criminal court with different publicity rules.

Neither Zolciak’s representatives nor Sheffield’s office had released detailed legal strategy statements beyond the initial denial and confirmation of representation as of August 21 reporting.

Discussion

1. How should media cover serious criminal allegations when the accused is a minor?

Juvenile privacy protections exist for a reason, yet celebrity cases often receive blanket coverage. Where is the line between public interest and protecting young people — including alleged victims — from lasting harm?

2. When a parent speaks publicly to deny charges against a child, what impact does that have on the legal process and on public perception?

Zolciak’s same-day denial aligned with her son’s defense, but high-profile statements can also shape jury pools and community opinion long before any trial.

If you follow Georgia juvenile justice, what procedural steps after a preliminary hearing matter most in cases like this?
