On 13 March 1943, Kitty and 12 other Jews at the factory, including her mother, were betrayed and taken to Gestapo headquarters. The family members were interrogated and charged at trial three days later with "endangering the security of Third Reich" and "illegally Germany with forged papers". They were told they would be executed and placed in front of a firing squad. After the squad conducted a mock execution, the victims were told their sentences had been commuted to hard labour.
