The attorney for Nazi hit man Heinrich Boere says a German court has ruled that his client is medically unfit for trial.

Maass brought charges in April against the 86-year-old Boere for the World War II murders of three men in the Netherlands when he was a member of a Waffen SS death squad that targeted civilians in reprisal killings for resistance attacks.

Though Boere was sentenced to death in absentia by a Dutch court in 1949 — later commuted to life imprisonment — German courts have blocked attempts to extradite him or enforce the verdict here.
