A woman has been deported back to Germany after she admitted to having served as a guard at a Nazi concentration camp during World War II.

Elfriede Lina Rinkel, 83, began working as a guard at the all-female Ravensbruck concentration camp in June 1944, and served there until the closing weeks of the war.

Under U.S. law, those who were involved in the Nazi's "Final Solution" must be sent back to Germany.

San Francisco Assistant Attorney General Alice Fisher tells the San Francisco Chronicle, "concentration camp guards such as Elfriede Rinkel played a vital role in the Nazi regime's horrific mistreatment of innocent victims."

"This case reflects the government's unwavering commitment to remove Nazi persecutors from this country."

According to IOL, established in 1939, Ravensbruck was the only Nazi concentration camp operated exclusively for female prisoners. At Ravensbruck, female guards with attack dogs forced the women inmates to march to slave labor sites each day, guarded them while they performed manual labor, and then marched them back to the camp, the officials said.
