Albuquerque zoo investigating giraffe death

Just days after the death of a giraffe at a Clovis zoo, officials at the Albuquerque BioPark say a 3-year-old female giraffe, Renna, has been euthanized.

Renna was eating her morning diet when she collapsed Wednesday. Veterinarians were called in immediately and cared for the giraffe until she was put down Thursday.

Veterinarians are performing blood tests and a necropsy to investigate her death.

Zookeeper Paul Huang says Renna was a gentle giant and a favorite of visitors during summer feedings.
