Martin Shkreli, a former pharmaceutical executive, was found guilty of multiple counts of securities fraud and conspiracy in 2017. He was accused of defrauding investors and manipulating the prices of drugs, including the life-saving Daraprim, which he had acquired and raised the price by more than 5,000%. Shkreli's conviction marked a significant legal victory in the fight against corporate greed and financial misconduct in the pharmaceutical industry.
