Hamburg Teen Arrested Over American Girl’s Death Linked to NMK Online Cult
German authorities arrested an 18-year-old Hamburg resident on Thursday, Oct. 22, 2026, on suspicion of murder linked to the international online group “Nefarious Maniac Kult” (NMK), BILD reported. Investigators from the State Criminal Police Office carried out the arrest alongside a raid on the suspect’s apartment in Hamburg.
The prosecutor’s office alleges that the suspect, who was 17 at the time of the offense, maintained contact via Discord with a psychologically unstable 14-year-old American girl between September and October 2026. Authorities state the teenager exerted severe psychological pressure on the victim, convincing her to inflict deep slash wounds and write his pseudonym “Kaz” along with the group’s name “NMK” in her own blood on her bedroom walls. The victim died by hanging a few days later.
Prosecution Pursues Indirect Perpetration Charges in Hamburg Case
Prosecutors are advancing a legal theory of murder through “indirect perpetration.” Under this approach, investigators assert that the accused did not physically execute the fatal act himself, but systematically compelled the victim to take her own life.
The investigation in Hamburg opened on Oct. 15 and Oct. 16, 2026, triggered by intelligence supplied by the FBI and the National Center for Missing and Exploited Children in the United States. Police records show the 18-year-old suspect has no prior criminal record. Both he and another teenage suspect in a related German case remain protected by the legal presumption of innocence.
Baden-Württemberg Case Involves Dozens of International Victims
The Hamburg arrest mirrors a separate prosecution in the federal state of Baden-Württemberg tied to the same digital network. Prosecutors in Karlsruhe filed charges against a youth from the Ludwigsburg district, currently 17 years old, who was arrested in October 2025.
Global Reach of the NMK and 764 Sadistic Networks
Law enforcement agencies link both German teenage suspects to the “Nefarious Maniac Kult” (NMK), described as an offshoot faction of the “764” extremist digital network. The broader network gained notoriety through the actions of 21-year-old online sadist Shahriar J., known by the alias “White Tiger,” who led a web of online predators targeting vulnerable minors globally.
