Overview
- Police arrested 15‑year‑old Kroy “KJ” Biermann Jr. on August 17 on felony counts of aggravated sodomy and aggravated sexual battery, and he is being charged in adult court.
- A classmate told investigators the alleged encounter happened on April 23 at a Life Time Fitness in Alpharetta when the pair went into a family locker room and the girl said no.
- Investigators say surveillance video places both teens at the gym and shows them entering the family changing area, while a hospital sexual‑assault exam reported no male DNA in the victim’s mouth or genital samples.
- KJ’s mother publicly denied the allegations, said he passed a voluntary polygraph, and his attorney called the claims false and pointed to the lack of DNA as part of the defense.
- The teen is held without bond at the Metro Regional Youth Detention Center, prosecutors began the case in adult court as required by state law, and a preliminary hearing is scheduled for early September with reports listing either Sept. 1 or Sept. 8.
