In 1965, Höcker was sentenced to seven years imprisonment for allegedly aiding and abetting in over 1,000 murders at Auschwitz. In 1989, he was sentenced to four years imprisonment for his alleged involvement in gassings in the Majdanek camp.
Höcker denied personal involvement in the alleged genocidal killings.
Furthermore, he believed that the prisoners were principally not killed.
