White rhino killed in zoo honoured with chocolate sculpture One month after a four-year-old white rhino was shot and killed for its horn in a zoo in Thoiry, French chocolatier Erick Thevenot has paid tribute to 'Vince' with a 190 kg chocolate sculpture, displayed in his shop in the eastern suburbs of Paris. The chef says he will also be making miniature chocolate rhinos for Easter, and plans to hand over the profits to the zoo.
