The Wall Street Journal reports that a long-sought suspect in the slaying of American journalist Daniel Pearl was secretly detained and interrogated by U.S. and Pakistani intelligence agencies before he died earlier this year. Lawyers and human rights advocates say the revelation suggests that the interrogation of Saud Memon may have led to his death. U.S. officials have not said where Saud Memon was held or interrogated. Legal aid and human rights groups in Pakistan said they have been told he was held at a secret CIA black site in Bagram, Afghanistan, before being turned over to Pakistan early last year. In April, Memon was dumped, badly injured and weighing less than 80 pounds, in front of his Karachi home. He died less than a month later. One human rights activist said, “His body looked like a 16-year-old boy’s. He had completely lost his memory. It wasn’t possible for him to survive. He couldn’t recognize his wife, children.” Daniel Pearl, a reporter for The Wall Street Journal, was kidnapped in Pakistan in January 2002 and then beheaded. Saud Memon allegedly owned the shed where Pearl was killed.
