More than a week has passed since thousands of dead pigs were first discovered floating in a river in Shanghai, but authorities have yet to explain fully where the pigs came from or why they died.
Fourteen of the pigs had tags in their ears identifying them as coming from Jiaxing city, in neighboring Zhejiang province. Getting to the bottom of the pig story, though, is tough. A visit to Zhulin village, where most everyone raises pigs, was greeted by serial denials.
