From what I found, Irmgard Furchner was mentioned in numerous sources in December 2022, when she was found guilty, while Bruno Dey was mentioned last in June-July 2022, when he was a witness in Furchner's process*. No word of other nazis in the last 12 months, appart from those that died, so all others mentioned in this topic might be dead already, as well.
