The trial of a 93-year-old former Auschwitz death camp guard has resumed after the suspect was deemed fit to face the court following a canceled session last week.

As the trial of Oskar Groening restarted, Lueneburg state court spokeswoman Frauke Albers said Auschwitz survivor Ivor Perl was due to take the stand Tuesday.

One session was cut short last week, and then the following day’s proceedings canceled, after the court said Groening was too sick to stand trial.

The former SS sergeant is being tried on 300,000 counts of accessory to murder and faces a possible sentence of three years to 15 years if convicted. Prosecutors argue his role sorting prisoners’ stolen valuables, which he admits, helped Auschwitz function.

His trial began in April and is scheduled through July.
