Zoo's oldest orangutan Inji dies January 09 2021 'We knew she couldn't live forever, but this really hurts, and I know many visitors are grieving along with us.' The Oregon Zoo said Saturday, Jan. 9, that Inji, a 61-year-old Sumatran orangutan, died. She was thought to be the oldest orangutan in the world. "We knew she couldn't live forever, but this really hurts, and I know many visitors are grieving along with us," said Bob Lee, who oversees the zoo's animal areas. "Inji's ability to connect with people was incredible. She inspired generations." Zoo officials said Inji's health had deteriorated during the past few weeks. When it was apparent that pain medications were not helping, zoo veterinary and care staff decided to humanely euthanize her.
