It took almost two years, but eventually Czech customs and police unravelled the network. In zoos or in the wild, tigers can live to well over 20 years. The movement of tigers across international borders is tightly controlled under international rules , while Czech laws go even further: each birth, death or sale of a tiger has to be recorded and the environmental inspectorate notified. Though much of this product was clearly destined for Vietnam, authorities believe that a significant amount was also traded within the large Czech-Vietnamese community. If you can imagine: an old freezer, without electricity, full of meat and dead bodies, in the garden for two years. Tigers were reportedly being exported multiple times, disappearing altogether, or not having their deaths recorded. Customs officials, however, believed he was also the likely source for the tiger products they were seizing en route to Vietnam.
