German investigators said on Tuesday they have identified eight suspected Nazi war criminals who worked at the former Stutthof concentration camp near Gdansk, Poland, NBC News reported.
"Following our investigations, we have identified four men and four women," Jens Rommel, the head of the central office for Nazi crime investigations in Ludwigsburg, Germany told the network.
Initial legal inquiries into "accessory to murder in several thousand cases" were forwarded to prosecutors' offices across Germany, Rommel said.
Local prosecutors will now need to assess whether there is enough evidence against the eight suspects to bring charges.
Between June and August 1944, thousands of people were killed by the Nazis in the gas chambers and with neck shots at the Stutthof camp, Rommel told NBC News.
The male suspects had worked as guards at the Stutthof camp, while the women had been employed as typists or phone operators, Rommel said.
He added that all of the suspects were born between 1918 and 1927, meaning they would be in their late 80s or 90s today.
Investigators in Ludwigsburg are continuing their research and investigations for former concentrations camps Auschwitz and Majdanek, while they recently expanded their search to former Nazi concentration camps Bergen-Belsen and Neuengamme, according to NBC News.
German prosecutors have in recent years have attempted to bring surviving Holocaust perpetrators to justice while there is still time.
The crackdown on Nazi war criminals began following the 2011 Munich trial of John Demjanjuk, a Nazi war criminal charged of assisting in the murder of 28,060 people at the Sobibor death camp and sentenced to five years.
In June, a German court convicted 94-year-old former Auschwitz guard Reinhold Hanning of being an accessory to 170,000 counts of murder.
Hanning's lawyers later said they would appeal the sentence.
Two others are currently on trial in Germany for "accessory to murder" during the Nazi regime.
