Identified and arrested on 14 June 1981 in Gransee, following an extensive investigation by the Stasi, Barth was tried again in 1983 in East Germany and sentenced to life imprisonment for war crimes. Barth, who claimed that he was only following orders, was the only former Nazi to have been judged for this massacre. Others Nazis involved had taken refuge in West Germany (such as General Lammerding, commander of the "Das Reich" division) and had not been judged. Lammerding took up residence in Bad Tölz.
