Finishing Daniel Pearl's Last Story

Twelve years ago yesterday, Wall Street Journal reporter Daniel Pearl drove off for an interview in Karachi, Pakistan and never came back. A month later, the FBI received a video ending with Pearl's killer holding his decapitated head. Pearl's friend and colleague spent years determining who the murderer really was. Asra Nomani is author of Standing Alone: An American Woman's Struggle for the Soul of Islam. She's also co-director of the Pearl Project.
