Weber interviews her about Anna Liebert. She tells him about 511 Kinderheim. Apparently, Tietze knew that much because she was involved in the investigation team created by the new government, and as a member, she saw how the former occupants of the orphanage where psychologically damaged by the curriculum enforced by the system. She said 511 was already up and running 20 years before she joined the work force and she just heard rumors about it. She knew about its name because her orphanage received some of the children 'kicked-out' of 511.
