Lack of Enforcement & Transparency

Despite widespread media coverage and multiple complaints, authorities have yet to take decisive action. Police capacity constraints and bureaucratic inefficiencies have delayed arrests and prosecutions. An active arrest warrant from Munich remains unexecuted, highlighting coordination issues between jurisdictions.

Kosan has minimized his online presence by deleting his LinkedIn profile and setting his Instagram accounts to private, limiting public visibility and removing incriminating content.

Call to Action

Victims and the public are urged to share information and help prevent further harm. Anyone with knowledge of Kosan’s whereabouts or additional evidence is encouraged to come forward.
