Toni Stock’s body is found in a cave in the beautiful Sölktal region. The ardent geocacher was beaten to death, his body discovered by Lissy Schneider, who was also out caching. Toni’s cell phone contains pictures of him being intimate with a young woman, Eva Nusser, who recently moved back into her deceased father’s home. Eva claims she was busy cleaning up the house at the time of the crime, and that she is not involved in caching at all.
