New York, February 18, 2014 –It’s one of the most notorious cold cases of World War II — 900,000 Jews transported by the Nazis to a camp in eastern Poland, never to be seen again. Rare documents and eyewitnesses claimed Treblinka was a death camp even more ruthlessly efficient than Auschwitz-Birkenau, but evidence was thin, because the Nazis destroyed all traces of the camp. Holocaust deniers have even claimed that it was only a transit camp. Now, 70 years later, a forensic investigator and her team have gained unprecedented access to excavate the site for the first time.

TREBLINKA: HITLER’S KILLING MACHINE, premiering Saturday, March 29 at 8pm ET/PT on Smithsonian Channel follows their quest to finally uncover clues that reveal the brutal mechanics behind an operation designed to murder people on a mass scale. It is airing as part of “Women in Science,” Smithsonian Channel’s special month-long programming block celebrating Women’s History Month.
