KJ Biermann Faces New Allegations After Prosecutors Reveal Cellphone Videos

A Fulton County court hearing has brought previously undisclosed allegations into the case against Kroy “KJ” Biermann Jr., the 15-year-old son of Kim Zolciak and former NFL player Kroy Biermann.

During a September 11 bond hearing, Deputy District Attorney Caitlin McGillicuddy told the court that investigators had previously found videos on KJ’s cellphone that prosecutors allege depicted sexual activity involving a female family member under the age of 12.

McGillicuddy said the device contained “multiple encounters” and alleged that the videos showed KJ using what she described as “predatory, derogatory” language toward the alleged victim. She also told the court that KJ had previously faced a sexual-battery charge involving a victim under 16 — information that had not been publicly reported before the hearing.

The prosecutor said the earlier incident had been reported in April 2023 and that KJ had been under court supervision since October 2025.

However, KJ’s attorney, Jason Sheffield, strongly disputed the characterization of that earlier juvenile matter.

Defense disputes prosecutors’ description

Following the hearing, Sheffield said the statements made in court “grossly misrepresent both the facts and the ultimate resolution” of the previous case.

According to the defense attorney, the matter involved inappropriate behavior between two middle-school students and did not result in an adjudication for statutory rape, sexual intercourse or a comparable offense.

Sheffield argued that presenting the earlier juvenile case in a different way could create a misleading impression of how it was ultimately resolved.

The dispute is significant because the newly disclosed allegations emerged during a hearing over whether KJ should remain in custody while facing a separate and much more recent criminal case.

KJ faces seven felony charges in separate case

KJ was indicted by a Fulton County grand jury on September 3 on seven felony counts stemming from an alleged April 23 incident involving a female classmate at a Life Time Fitness facility in Alpharetta, Georgia.

The charges include aggravated child molestation, aggravated sexual battery, aggravated sodomy, three counts of aggravated sexual battery against a child under 16, and false imprisonment.

According to the allegations contained in court documents, the girl was 15 and KJ was 14 at the time.

She accused KJ of sexually assaulting her inside a co-ed sauna, alleging that he repeatedly attempted to have sexual intercourse despite her objections. She also alleged that he forced her to perform oral sex and digitally penetrated her.

The girl reported the alleged incident to her family the following day and was subsequently examined at Wellstar North Fulton Medical Center. The article reported that no male DNA was found in her mouth or vagina.

KJ was arrested on August 17 and taken to Atlanta’s Metro Regional Youth Detention Center, where he was initially held without bond.

KJ, his attorney and his family have denied the allegations.

Prosecutor and alleged victim oppose release

During the September 11 hearing, prosecutors argued that the alleged victim in the April case suffered documented physical injuries and described the incident as predatory.

The prosecution requested a $190,000 bond, while Sheffield asked the court to release KJ on $65,000 bond.

The alleged victim also provided a statement to the judge, asking the court to take her safety into consideration before deciding whether KJ should be released.

She said she had been living in fear over alleged threats that KJ would come after her if he were released. She also said members of her family had received emails and phone calls connected to the situation.

The victim told the court that she was no longer afraid only for herself, but also for her family.

Defense asks for juvenile court

KJ’s legal team has also been seeking to have the case handled in Fulton County Juvenile Court rather than through the adult criminal system.

In a September 8 filing, Sheffield argued that KJ is still an adolescent whose development is ongoing. He pointed out that KJ was 14 when the alleged April incident occurred.

The attorney also warned that the aggravated charges could carry a mandatory minimum sentence of 25 years in prison without parole if KJ were prosecuted and sentenced as an adult.

Sheffield said his client expected to plead not guilty to all charges at his October 14 arraignment.

Defense highlights KJ’s life outside the case

As part of the request for bond, Sheffield emphasized KJ’s record as a student and athlete.

The attorney described the teenager as a high school student in good standing who had demonstrated strong academic performance and participated in extracurricular and community activities.

He also said KJ was an accomplished football player who had received scholarship offers because of his athletic ability.

During the hearing, Sheffield described his client as quiet rather than outspoken and said the legal proceedings had been deeply traumatic for him.

Kim Zolciak and Kroy Biermann support their son

Both of KJ’s parents attended the hearing.

Kim Zolciak arrived with their eldest daughter, Brielle Biermann, while Kroy Biermann sat separately in the courtroom gallery.

The former couple, who are estranged and have been involved in a contentious divorce, share four minor children: KJ, Kash, Kane and Kaia. Kroy also previously adopted Kim’s two older daughters, Brielle and Ariana.

Kim has publicly defended KJ, previously describing the allegations against her son as “reckless and deeply troubling.”

The family has continued to maintain KJ’s innocence.

Bond granted under strict conditions

Judge Melynee Leftridge ultimately granted KJ a $200,000 bond on September 11, according to subsequent reports.

The conditions are extensive. KJ must remain at his mother’s home, attend school virtually, wear electronic monitoring and surrender his passport. He is also prohibited from using a cellphone or social media and cannot have contact with the alleged victim or minors.

Meanwhile, prosecutors have continued pursuing the investigation, including seeking forensic interviews with minors in connection with the case.

The newly disclosed cellphone allegations have added another layer to an already serious legal case, but the claims remain allegations. KJ’s attorney continues to dispute the prosecution’s characterization of the earlier juvenile matter, and KJ is presumed innocent unless proven guilty in court.
