WARNING: THIS REPORT CONTAINS GRAPHIC CONTENT. A Fulton County courtroom opened a new chapter this week in the case involving 15-year-old KJ Biermann, when prosecutors said investigators found videos on his cellphone that allegedly show sexual acts with a family member under 12. The revelation expanded a case already tied to multiple felony counts and drew emotional testimony, legal maneuvering and a debate over whether the teen should remain jailed or be released on bond.

During Friday’s hearing, Deputy District Attorney Caitlin McGillicuddy told the judge that detectives discovered several videos on KJ’s phone. She said the clips purportedly show “multiple encounters” and include language she described as “predatory” and “derogatory.”
The prosecutor framed this revelation as particularly significant because, she said, it represents a separate, previously undisclosed juvenile matter involving a victim under 12.
How the new claim fits with earlier allegations
McGillicuddy said KJ had been under court supervision since October 2025 after the earlier report involving the younger family member, which was allegedly first reported in April 2023. She also told the court this would be the second time the teen faced accusations of a sexual nature involving female victims.
In response, defense lawyer Jason Sheffield sharply disputed the prosecutor’s depiction of the prior juvenile case. He told media the earlier incident stemmed from “inappropriate, crude behavior” between middle-schoolers and that it did not end in an adjudication for statutory rape or sexual intercourse.
Indictment specifics: a list of the felony charges
A grand jury returned an indictment in early September that names the teenager in a string of serious counts. The complaint alleges an April incident with a female classmate and includes:
- Aggravated child molestation
- Aggravated sexual battery
- Aggravated sodomy
- Three counts of aggravated sexual battery against a child under 16
- False imprisonment
The accused was 14 at the time of the alleged April incident and faces multiple felony counts now that he is 15.
Victim’s account and medical follow-up
Court papers say the alleged assault occurred at a Life Time Fitness center in Alpharetta on April 23. The female classmate, reported to be a freshman, told investigators the events unfolded in a co-ed sauna.
According to the written statement, she said the teen tried repeatedly to force sexual intercourse despite her refusals, forced oral sex and later digitally penetrated her. The complainant was examined at a medical facility the next day; court filings note that tests did not find male DNA in her mouth or vagina.
Bond hearing: defense asks for release, prosecutor seeks high amount
At the hearing, defense counsel requested bond set at $65,000 and offered that KJ’s mother, former reality star Kim Zolciak, would supervise him if he were released. Sheffield described KJ as a quiet teenager with strong school and athletic records.
McGillicuddy pushed back. She emphasized the alleged victim suffered “documented physical injury” and described the conduct as “predatory.” The prosecutor asked the judge to set bond at $190,000.
Judge Melynee Leftridge said she would rule by Monday on whether the teen, currently held at the Metro Regional Youth Detention Center, could be released.
Victim’s written plea read in court
A statement from the alleged victim was read aloud during the hearing. In it, she pleaded with the judge to weigh her safety before any release decision. She wrote that she has been “living in fear” because of alleged threats connected to the case.
The victim said the danger extends to her family, reporting that relatives have received emails and phone calls tied to the situation. “The thought of him being released scares me,” she wrote.
Family presence and courtroom atmosphere
Members of the Biermann family attended the proceedings. Kim Zolciak and their eldest daughter sat together in the gallery. KJ’s father, former NFL player Kroy Biermann, appeared visibly strained and sat a row ahead of them.
KJ remained largely stoic through the hearing. Supporters and family members have publicly and privately defended him while the legal process moves forward.
Defense strategy: juvenile court transfer and expected pleas
Following a sudden cancellation of an earlier hearing, Sheffield filed a motion to move the matter to Fulton County Juvenile Court and to keep proceedings confidential. He argued the teen’s ongoing development and the severe penalties attached to the aggravated charges warranted juvenile consideration.
Sheffield told media his client plans to enter not-guilty pleas at an arraignment scheduled for Oct. 14. He further warned that aggravated convictions could carry a mandatory minimum sentence of 25 years without parole, underscoring the gravity of the situation for the young defendant.
Detention center conditions and next legal steps
KJ has been held at the Metro Regional Youth Detention Center since his August 17 arrest. The facility enforces strict routines and tight visitation rules for juveniles in custody.
With the judge set to consider bond, the case will continue through the juvenile and criminal justice systems, with pretrial proceedings and the scheduled arraignment forthcoming.
What both sides say publicly
- Defense: Calls the allegations a tragedy for a teen presumed innocent and insists earlier juvenile matters were mischaracterized.
- Prosecution: Points to alleged video evidence and the victim’s statement to justify detention and a higher bond.
Household impact and public visibility
The matter has thrust the family into the public eye. Photos obtained by media outlets show parents and siblings arriving at and leaving homes and court buildings appearing stressed.
KJ is one of several children in the household. His parents share custody histories and blended family ties with older daughters and younger siblings who have also been referenced in media coverage.
