BERLIN (AP) — A German court trying a 94-year-old ex-SS sergeant who served as an Auschwitz death camp guard has declined to hear evidence from an Auschwitz survivor who traveled from the U.S.

The 88-year-old Joshua Kaufman hadn't been invited to testify but some of the Holocaust survivors and relatives who joined the trial as co-plaintiffs hoped he could tell the Detmold state court about how he had to remove corpses from gas chambers.

However, the court already heard evidence about how victims died, news agency dpa reported. Presiding judge Anke Grudda said Friday: "No further evidence is needed. The court has no doubts on this aspect."

Defendant Reinhold Hanning is charged with 170,000 counts of accessory to murder over allegations that as a guard he helped Auschwitz function. Other survivors have testified.
