Police have released images of the last moments of the 26-year-old mother who was found dead in a Nazi concentration camp bunker from where the SS coordinated mass exterminations after it was confirmed that she was murdered.

After an autopsy has been performed on her body, and has confirmed that she was murdered and suffered a violent death now homicide investigators have released these two images of the victim, who has been named as Bianca Simon.

Bianca, leaves behind a five-year-old son and was found dead at around 10pm on Monday evening (19th July).

Investigators reported that her lifeless corpse was found inside a World War II bunker near the Sachsenhausen concentration camp from where the SS coordinated mass exterminations.

The bunker named ‘Karo Ass’ (Ace of Diamonds in English) is located in a forest near Oranienburg, a town in the north-eastern German state of Brandenburg, not far from the capital Berlin.

The young woman worked as a geriatric nurse and can be seen in the CCTV image from the Oranienburg train station captured pushing a bicycle and sporting a top with the words “Hakuna matata” on it on Thursday 15th July.

According to investigators, she died shortly after these images were recorded.

She was reported missing by family member last Saturday.

An autopsy performed on her body has confirmed that she died violently, although the Neuruppin public prosecutor’s office does not believe that a sexual offence was committed.

Spokesperson Torsten Sauermann said: “We have not found any traces of rape.”

Her bicycle, which has a child seat on it, was found near the Nazi era telecommunications bunker where she was found dead.

Police are asking for witnesses who may have seen the young woman after 1 pm on 15th July to come forwards.

Witnesses can contact the Oberhavel police station or any other police station with information.

The Sachsenhausen concentration camp was used from 1936 to the end of the Third Reich in May 1945 and it mainly held political prisoners throughout the war, among whom Joseph Stalin’s eldest son Yakov Dzhugashvili.

When the Nazis set up the camp, they also built an arms control department, a dog training school, storage and intelligence units, and an above-ground communications bunker, known as the Funkbunker Karo Ass (Ace of Diamonds).

Bianca’s corpse was found in the corridors of the communications bunker, that used to belong to the SS (Schutzstaffel), which was Adolf Hitler’s paramilitary organisation responsible for the genocidal killing of an estimated 5.5 to 6 million Jews and millions of other victims during WWII.

Bianca’s five-year-old son has since been taken into care by his grandmother.
