In 1943, Kató Weisz lost her father, who died as a labor serviceman at the front. In May 1944, the 9-year-old girl, now half-orphaned, was transported from Aszód to the ghetto of Rákoscsaba with her mother, Boriska Weiszzné Radó. In the ghetto, 10-12 people were crammed into a room. At the beginning of June, they were taken to the collection camp at the sugar factory in Hatvan, and were soon deported. The train of 2961 people reached the border at Kassa (Kosice) on 13 June and arrived at Auschwitz-Birkenau on the 14th or 15th. Kató was killed the same day. His mother spent the next six months in Birkenau. When the Red Army approached the camp, she was transferred to KL Bergen-Belsen. It was probably here that she contracted typhus. A few days later she was moved on to the subcamp of the Buchenwald concentration camp at Ascherleben to work in a Junkers aircraft factory. Typhus killed her on 18 January 1945.
