The sudden death of a billionaire in southern China is causing police to ask: Was it murder by cat meat? Long Liyuan, 49, died on Dec. 23 in wealthy Guangdong province after sharing a dish of slow boiled cat meat stew, a southern delicacy, with two men over a business lunch. One of the men, local official Huang Guang, was arrested by police on Friday on suspicion of poisoning the hotpot with a toxic herb. Police say Huang and Long had economic disputes. Huang, deputy director of agriculture in Guangdong’s Bajia township, is suspected of poisoning the hotpot with the herb Gelsemium elegans, according to a statement on the microblog of the investigating police. The poisonous plant is found in forests in parts of China…Long and Huang had met for lunch to discuss a business contract. Long, who ran a forestry company in Guangdong, wanted to lease a piece of woodland and develop it, the Nanfang Daily, the mouthpiece of the Guangdong Communist Party, reported Tuesday.
