OKLAHOMA CITY, OK (KTRK) -- Zookeepers in Oklahoma City say they are heartbroken over the sudden death of a beloved Asian elephant.
The 37-year-old Chai was found dead in the elephant yard at the Oklahoma City Zoo & Botanical Garden on Saturday.
Chai was at the center of a fight last May, when she was moved from Woodland Park Zoo in Seattle, Washington to Oklahoma.
Animal rights advocates said Chai would be better off in a sanctuary in California, where the winters are not as harsh as those in Oklahoma City.
But, zoo officials say Chai's death has come as a complete shock.
"She was normal behaving yesterday," says official Tara Henson. "It's really hard for us. We think of these animals as part of our family."
A necropsy is set to be performed to determine Chai's cause of death.
She is the second elephant to die at the Oklahoma Zoo in the past four months.
A viral infection killed a four-year-old Asian elephant named Malee in October.
The rest of the elephant herm seems to be okay, according to zoo officials.
