Having trained as a nurse, Schulz moved to Karlsruhe in the early 1970s and took up residence in a flat with Günter Sonnenberg, Knut Folkerts and her boyfriendChristian Klar – who would all at a later time be convicted of terrorist crimes. It was around this time that Schulz was exposed to radicalism, and it was in the seventies that Schulz decided to embark on a life of terrorism.
In 1978 she was involved in a gun-battle with four Dutchcustoms men in the border town of Kerkrade, which resulted in the deaths of two of the Dutchmen.
Between November 1978 and April 1979, Schulz was involved in at least three bank robberies.
