Pathologists who tested samples from two women accused of smearing a nerve agent on the estranged half-brother of North Korea’s leader revealed Tuesday that the two suspects had not been poisoned themselves. Indonesian Siti Aisyah and Doan Thi Huong, a Vietnamese, pleaded not guilty to murder charges in a Malaysian court earlier on Monday. On the morning of Feb 13, Kim Jong Nam, the half-brother of North Korean leader Kim Jong Un, was at Malaysia’s low-cost Kuala Lumpur International Airport 2 and headed for his flight to Macau, when he was poisoned by VX nerve agent.
