On a cold January morning of 1968, a two-man border guard patrol spotted footprints in the so-called controlled zone in Devínská Nová Ves. The patrol immediately began examining the male footprints that led them through the damaged wire barrier to the bank of the Morava River. Not even the freezing morning of January 18 stopped the unknown man from crossing the icy river. The man left a pack of cigarettes and a jacket on the riverbank. Based on this evidence, the border guard investigators concluded that this successful border crossing was carried out by a citizen of the German Democratic Republic.
