Eight concentration camp suspects have been identified by "Nazi hunter" Jens Rommel and are now under investigation for their involvement as accessories to murder, German news media reported.
Rommel, of Germany's Central Office for the Investigation of Nazi Crimes in Ludwigsburg, told news agency DPA that the cases of the eight elderly suspects in Germany were forwarded to prosecutors across the country.
"The investigations concern four men and four women who worked at the German concentration camp in Danzig," said Rommel, according to The Local.
The 2011 conviction of former death camp guard John Demjanjuk in Germany marked a change in prosecuting Nazi-era crimes, noted The Local.
Demjanjuk was convicted on the basis that he served at the Sobibor camp in occupied Poland as a cog in the Nazis' killing machine, rather than on a specific crime he had committed, opening the doors to prosecute others working at such facilities.
Demjanjuk had lived for years in the United States as an autoworker after World War II before he was convicted of 28,060 counts of being an accessory to murder, said NBC News.
The male suspects worked as guards and the female suspects were employed as secretaries or telephone operators at the camp, said The Local. The suspects were all born from 1918 and 1923, putting their ages in the 80s and 90s.
In June, Reinhold Hanning, 94, a former guard at the Auschwitz death camp, was sentenced to five years in prison after he was found guilty of being an accessory to the murder of at least 170,000 people, said BBC News.
In a four-month trial, Hanning was determined to be an SS guard at Auschwitz from 1942 to 1944.
In 2015, another German court sentenced Oskar Groening, 94, to four years in jail as an accessory to the murder of at least 300,000 people at Auschwitz, said BBC News. Groening was known as the "book-keeper of Auschwitz" and accused of counting banknotes confiscated from prisoners.
NBC News noted that German prosecutors now have to decide whether there is enough evidence to bring charges against the new suspects.
