"Chemical Sally" is more recently known as the 5 of hearts in the 'Top 55 Most Wanted Iraqis' pack of cards. Huda Salih Mahdi Ammash, Sally's real name, was captured by US forces and was taken into custody on Sunday. Sally was 53 on the list of 55.
Ammash is one of Iraq's biological weapons scientists say defence officials. Ammash is believed to have been a key figure in rebuilding Baghdad's biological weapon capabilities.
Ammash has a master of science in microbiology from TWU in Texas, and is said to have been trained by the father of Iraqis biological weapons program: Nassir al'Hindawi.
