My guess is... he could have fingered others, if he had been allowed to live.
Margaret Hassan, the aid worker who "disappeared" in Iraq, probably had "dirt" on the UN, too (the oil-for-food scandal). I don't think she was involved in the oil-for-food scandal, but I'd bet she had some suspicions about the program.
Dublin-born charity worker Margaret Hassan moved to Iraq 30 years ago, and began working for Care International soon after it began operations there in 1991. When she was kidnapped, she had been head of the charity's operations in the country for some 12 years.

It has focused efforts in Iraq since the war on providing emergency relief and medical aid, and restoring access to clean water.
