The Simon Wiesenthal Center has sent the German government a list of 80 people it believes murdered Jews while serving in Nazi death squads in World War II and who may be still alive, the head of the Israel office of the organization said.

The push for an investigation into members of Einsatzgruppen, or death squads, was triggered by a landmark conviction in 2011 of John Demjanjuk, a guard at the Sobibor death camp, said the Wiesenthal Center's Efraim Zuroff.

Demjanjuk was the first Nazi war criminal to be convicted in Germany for being a guard at a death camp without evidence of a specific crime or victim. He died in March 2012 at age 91.
