[JURIST] The Austrian Justice Ministry [official website] has dropped its case against a former Nazi psychiatrist accused of killing children at a Vienna clinic after he was ruled unfit for trial. The government said Wednesday that Heinrich Gross, 89, suffers from dementia and could not stand trial. Gross worked at a children's clinic in Austria where 789 children were killed as part of a Nazi euthanization campaign. He was jailed briefly following the war, but he was never convicted in subsequent criminal trials, with the most recent in 2000 being halted [BBC News report] due to Gross' poor health. A justice ministry spokesman said Gross was the last Nazi against whom charges were being investigated in Austria. Gross managed to escape notice and worked as a forensic psychiatrist in Vienna courts as late as 1997. Deutsche Welle has more.
