A string of unsolved murders in San Francisco's Chinatown in the 1970s led police to the door of a young Korean immigrant named Chol Soo Lee — who was quickly arrested and sentenced to life in prison. But when investigative journalist K.W. Lee started digging into the case, he discovered a world of twisted law and order that went far deeper than one man. The articles K.W. wrote about what he uncovered in Chinatown shocked Asian Americans across Northern California to stand up and demand justice for Chol Soo Lee — and themselves. Guests: Sojin Kim, curator at the Smithsonian Center for Folklife and Cultural HeritageRanko Yamada, friend of K.W. Lee and Chol Soo Lee Julie Ha, journalist, writer and co-director of the documentary film "Free Chol Soo Lee"
