A Minnesota Nazi commander has been discovered living in Minneapolis and may now face deportation, according to a CNN report.

The so-called Minnesota Nazi, Michael Karkoc, who is now 94, fled to the United States in 1949 and was granted entry by lying, even though the SS Galician Division and a Ukrainian nationalist organization he served in were both on a secret American government blacklist of organizations whose members were forbidden from entering the United States.

Karkoc lied and told American authorities that he had performed no military service during World War II. Because of his deceitfulness, he was allowed to move to the United States.

Karkoc was an officer and founding member of the SS-led Ukrainian Self Defense Legion and later was an officer in the SS Galician Division. The Ukrainian company he commanded massacred civilians. Nazi SS files say he and his unit were also involved in the 1944 Warsaw Uprising, in which the Nazis brutally suppressed a Polish rebellion against German occupation.

Now living in Minnesota, the former Nazi could face deportation to Germany for his role in the war crimes. German prosecutors are required to open an investigation if there is enough "initial suspicion" of possible involvement in war crimes.

Polish prosecutors announced Friday that they will investigate the Minnesota Nazi and provide "every possible assistance" to the U.S. Department of Justice, which has previously used lies in immigration papers to deport dozens of suspected Nazi war criminals.
