"That's him! That's Klaus Braun! His father Ernst was an engineer and helped with the crematoria of Auschwitz! Very efficient! 30 trays, 3 bodies for tray, 90 corpses in ashes at a time." ― Aaron Lesnick

Klaus Braun, aka Abraham Klein, was a Nazi criminal responsible for the Holocaust in Nazi-Germany. He appeared in Season Five of CSI:NY.

Following in his father's footsteps, Braun was a member of the Hitler Youth in 1941 to 1943 where he was assigned to capture the Jews during the Final Solution.

In 1942 in Poland, Braun was a neighbor of Esther Schnitzler along with her family where he would create an ambush against them.

He betrayed Esther and her family by sending them to Auschwitz where they were executed one by one and thrown into the ditch.
