The Fulton County District Attorney's Office filed emergency motions Thursday, Sept. 17, seeking court-ordered forensic interviews of additional minor children in the sexual assault case against Alpharetta teenager K.J. Biermann.

The filings suggest the case may extend beyond the original alleged victim, who, according to the indictment, was assaulted at an Alpharetta gym in April.

Prosecutors stated in the motion that they have a good-faith basis for concern about additional minors who need forensic interviews connected to the case, WSB-TV reported. The DA's office is also asking the court to revisit Biermann's bond conditions and to review explicit video evidence in a closed courtroom under seal.

Biermann, 15, is the son of former Atlanta Falcons player Kroy Biermann and former "Real Housewives of Atlanta" star Kim Zolciak. He faces seven felony charges as an adult: aggravated child molestation, aggravated sexual battery, aggravated sodomy, false imprisonment, and three counts of sexual battery against a child under 16.

Alpharetta police arrested him Aug. 17.

Judge keeps courtroom open, limits media access

Fulton County Superior Court Judge Melynee Leftridge denied a defense request to close the courtroom, ruling that existing protective measures are adequate. She did grant a motion restricting media recording and photography, and juvenile court records tied to the case will be filed under seal.

Biermann's defense attorney, Jason Sheffield, filed a notice confirming his client's passport had been surrendered in compliance with the bond order. According to reporting from Page Six, Sheffield said his client intends to plead not guilty to all charges at his Oct. 14 arraignment.

Sheffield also disputed how prosecutors have characterized a prior juvenile matter from 2023, according to Page Six, arguing that the earlier case involved less serious conduct between two middle-school-age peers and did not result in any adjudication comparable to statutory rape or a similar offense.

Per the indictment, Biermann had been under juvenile court supervision stemming from that 2023 case, in which investigators reportedly found videos on his cellphone showing him allegedly assaulting someone close to his own age at the time.

Bond conditions remain strict

Under the $200,000 bond approved Sept. 11, Biermann must remain at his Alpharetta home and attend school virtually. No one under 16, including his siblings, is permitted to live in or visit the home. He may leave only for medical and court appointments, and he's barred from using a cell phone or social media.

At the bond hearing, prosecutors argued against granting bond at all, contending — according to reporting on the hearing — that no set of conditions could adequately protect potential future victims, including people close to Biermann.

No date has been set for the emergency bond modification hearing.
