Jewish patients were either murdered in the wake of T4 or concentrated in special hospitals and later probably deported to extermination/concentration camps.
In contrast, in Poland psychiatric patients were shot by SS units from the very beginning of the German occupation as Filip Marcinowski explained. Later,the National Socialist occupiers resorted to killing patents in gas vans, and other patients were deported to Auschwitz-Birkenau and murdered there.
Though occupied later during the attack on the Soviet Union in 1941, a similar picture can be seen in the Baltic states, as shown by Björn Felder, where the extermination of people with disabilities started immediately after occupation with random mass shootings in parallel with the murder of the Jewish population.
In the subsequent panel, Sara Berger presented the results of her study on the activities of the T4 staff - the perpetrators of the mass murder of the people with disabilities in the German Reich and Austria - during Aktion Reinhardt later on. They used their experience in mass killings to murder the Jews deported to the extermination camps.
