The scheme collapsed in the autumn of 1994 when authorities in Germany and Switzerland arrested the EKC leadership and managed to seize about 500 million marks of the money paid by the EKC's victims. The collapse of the EKC led to public unrest in the heavily affected parts of Switzerland, where many participants, refusing to believe that they had fallen prey to a Ponzi scheme, organized public demonstrations in support of the EKC leadership, and prosecutors received death threats.
Damara Bertges, the EKC's leader, was convicted in 1997 by a German court to 8 years imprisonment for fraud and participation in a criminal organization, and was set free on probation after serving five years. Her husband Harald and their accomplice Spachtholz, as well as another associate, were each convicted to four and a half years of imprisonment.
