The preliminary autopsy results show that is was a heart attack that killed the elephant Kathy Sh-Boom.
She was the unofficial mascot of the Niabi Zoo, where she'd lived since 1964. The staff at Niabi say they now have to find a new companion for there other elephant Babe. They fear that Babe will become depressed at the loss of Kathy.
The zoo staff are trying to keep Kathy's memory alive by helping her species survive. Niabi Zoo Director, Tom Stalf says the there are only 30,000 Asian Elephants like Kathy in the wild. They are an endangered species and the zoo has been donating to the Sumatra Fund to help preserve the elephant population. Stalf also wants to raise money for a memorial plaque at Kathy's pen. They are raising money by selling Isabelle Bloom sculptures at the zoo.
Kathy was buried on zoo property on Friday.
