Federal wildlife investigators have broken up an international smuggling ring that trafficked in sawed-off rhinoceros horns for buyers in Vietnam and China who believe they cure cancer, a U.S. newspaper has reported, according to AP. More than 150 federal agents led raids into homes and businesses in several states last weekend, the Los Angeles Times reported Wednesday. (http://lat.ms/w5x5no) Three of the alleged traffickers caught in Southern California were 49-year-old Jimmy Kha, his 41-year-old girlfriend Mai Nguyen and Kha's 26-year-old son Felix. Each faces four counts of rhino horn trafficking in violation of federal laws protecting rare and endangered species. More than $1 million in cash, $1 million in gold bars, diamonds and Rolex watches, along with 20 rhino horns, were seized in the raids. Most of the horns end up in Vietnam, or sometimes China, where there's a misconception that they can cure cancer, said Crawford Allan, North American director of TRAFFIC, a World Wildlife Fund program. The arrests and seizures resulted from an 18-month investigation, said Edward Grace, deputy chief of law enforcement for the wildlife service. The undercover operation was forced into the open when accused trafficker Wade Steffen of Hico, Texas, and his wife and mother were found with $337,000 in their luggage at a Long Beach airport, authorities said. -- SPA
