The chemist could have easily spoken out. Protections would have been put into place to ensure that she and her family wouldn't have been harmed. Obviously blackmail and fear plays a part here, but evident by the fact she didn't seem to be upset about being caught nor deny anything, sounds like a classic case of a sociopath (or even part sociopath). How could you live with yourself knowing for ten years you've ruined countless lives? Whether she believes it or not, she had her chance and the blame sadly does lay with her and the prosecutor for being complacent in the crimes taking place.
