'Lilly Tofler',  a secretary, had attempted to smuggle a letter out to her lover in the Birkenau men's camp. The letter was discovered, according to Rosenthal, by either Grabner (head of the Political Department) or Kirschner, another guard there. She was then interrogated by Boger and later shot to death.
