As many as 746 murders and attempted murders, over a 21 year period, may be linked to a German neo-Nazi group.
The investigation stretches back to 1990, the year of German reunification. A surge of racist violence followed, particularly in the formerly communist east and poorer parts of the west.
It ends with cases from 2011. Late that year, the self-styled National Socialist Underground emerged as alleged suspects behind the murder of eight Turkish men, a Greek and a policewoman between 2000 and 2007. The group, whose sole surviving alleged member is currently on trial, also is suspected of carrying out two bombings in which dozens of people were injured.
