>> Gracie and Bruno, white rhinos at the Thoiry Zoo and Wildlife Park in Paris, are lucky to be alive. Their four-year-old companion, Vince, was shot and killed by poachers who broke in overnight. Police say Vince was found dead in his enclosure with three gun shot wounds to his head and one of his horns missing.
>> It's a enigma->> Zoo director, Thierry Duguet, says Vince's second horn was partially cut. He says the intruders may have been scared off or their equipment failed.>>
> An unimaginable crime that Duguet hopes will be solved before the poachers can strike again.
