Why an upcoming Nazi guard's trial may be one of the last

Oskar Groening, 93, has been charged with complicity to more than 300,000 counts of murder for his involvement in the Auschwitz concentration camp in the early 1940s. His trial is scheduled for next year. But as Auschwitz survivors prepare to mark the 70th anniversary of the camp’s liberation, Mr. Groening’s trial may be one of the last attempts to prosecute those involved in the murder of more than one million Jews. Many, like Groening, are in their 90s.
