Sasha Yemelianova has learned about the Babi Yar massacre in school before, but going on USC Shoah Foundation’s IWalk and leading it for other students has given her a new perspective of the massacre and its memorialization. German and SS police units murdered nearly the entire Jewish population of Kiev – 33,771 men, women and children – at the Babi Yar ravine outside the city on September 29 and 30, 1941. About 75,000 more Jews as well as communists, Roma, and Soviet prisoners of war were also murdered there over the next few months.
