She lived in an apartment in the small town of Breitling, Lower Saxony. Birgit was in the middle of a divorce when she disappeared. Before she vanished, her husband was meant to make an appearance to clarify the details about their separation.According to the pair's agreement, Birgit was to receive a settlement of 500,000 DM from her husband. This was considered a precedent for investigation. Following her disappearance, Harald became an immediate suspect as the police assumed that he had a concrete reason to harm her. A suicide was also considered a possibility by investigators, but Birgit's body was nowhere to be found.Unfortunately, her investigation stalled due to lack of leads and evidence.
