Twenty years after his death at the hands of terrorists, the fight for justice for journalist Daniel Pearl continues, with the United States urging Pakistan to keep his kidnappers behind bars while his killer awaits a 9/11 trial at Guantanamo Bay.

Pearl, a 38-year-old Jewish American known as “Danny” to friends and family, was in Karachi after the Sept. 11 terrorist attacks, investigating Pakistani terrorist groups on behalf of the Wall Street Journal. He was following leads on al Qaeda and Richard Reid, the British-born “Shoe Bomber” accused of trying to blow up an American Airlines flight in December 2001 when he was abducted. Just over a week later, Pearl was beheaded on video by al Qaeda operatives on Feb. 1, 2002.
