The first gorilla born in captivity, who went on to become the oldest known member of her species, has died at the age of 60, officials at the Columbus, Ohio, zoo that served as her home said on Tuesday. Colo, a Western lowland gorilla, was found dead on Tuesday morning in her enclosure, the Columbus Zoo and Aquarium said in a statement. She was the oldest gorilla on record and exceeded her normal life expectancy by more than two decades, said Patty Peters, a zoo spokeswoman.
