A nurse faces murder and manslaughter charges as he goes on trial this week over the deaths of 29 patients in what has been described as the biggest series of killings in post-Second World War Germany.
Stephan Letter, 27, could face life in prison if a state court in Kempten convicts him on 16 counts of murder, 12 of manslaughter and one of mercy killing. The trial opens tomorrow.
The alleged killing spree at the hospital in Sonthofen, in the Bavarian Alps, began in February 2003, less than a month after the nurse started working there.
The last suspect death occurred in July 2004.
