German authorities detained an 18-year-old in Hamburg on Thursday, prosecutors confirmed Friday. The suspect is accused of indirectly causing the death of a 14-year-old girl in Indiana.
The arrest followed information provided by the Federal Bureau of Investigation. Timothy J. O'Malley, the FBI special agent in charge for Indianapolis, stated that his office coordinated with the Fort Wayne Police Department to share details that helped secure the detention.
Prosecutors in Hamburg charged the suspect with indirect murder and grievous bodily harm. They allege he was part of an online group called Nefarious Maniac Kult, or NMK, which is linked to a wider network known as COM.
Between September and October, when the suspect was 17, he used the platform Discord to influence the Indiana girl. Prosecutors described her as psychologically fragile. He allegedly pressured her to cut herself and write the letters NMK on a wall using her own blood.
The girl was also made to send video recordings of these acts to the suspect. A few days later, she hanged herself in her bedroom. Prosecutors said the suspect requested a video of her death, hoping it would improve his status or gain him entry into the group.
The Fort Wayne Police Department said its homicide unit identified the suspect as a contributor to the juvenile's death. O'Malley said anyone who targets or exploits a child should understand there is no safe haven from justice. He added that the FBI will work with global partners to hold suspects accountable regardless of where they live.
The FBI has reported a sharp rise in nihilistic violent extremism. Director Kash Patel said the bureau saw a 300% increase in such cases from September 2024 to September 2025. Many of these cases involve a group known as 764, whose members encourage self-harm and violence while urging victims to produce documenting videos.
