The vice-mayor of Harbin, in northeastern China, was a rising star in the Communist Party when he stumbled on a corruption scheme involving other senior Party members. Afraid he would blow the whistle, they had him arrested on trumped-up charges, and a few years later he died in prison. Authorities say it was a suicide, but his wife thinks it was murder. The story shows that China still has a long way to go in protecting the rights of its citizens. NPR's Rob Gifford reports.
