Germany shelves Nazi crimes probe of US man

German prosecutors have shelved their Nazi war crimes investigation of a retired Minnesota carpenter whom The Associated Press exposed as a former commander in an SS-led unit, saying Friday that the 96-year-old is not fit for trial.

The decision came more than two years after the AP published a story establishing that Michael Karkoc commanded a unit in the SS-led Ukrainian Self Defense Legion accused of burning villages filled with women and children, based on wartime documents, testimony from other members of the unit and Karkoc's own Ukrainian-language memoir.
