(CNN) — A 41-year-old elephant named Patience charged and killed a Springfield, Missouri, zookeeper who had come to feed her Monday.
John Phillip Bradford, 62, died in the elephant enclosure at Dickerson Park Zoo, according to Springfield Police Department spokeswoman Lisa Cox. He was the manager of elephants, and had worked at the zoo for more than 25 years, Cox said.
Bradford was in the enclosure with two other workers when Patience charged him. The other two workers were unharmed, Cox said.
What set off the incident is unclear.
The zoo referred questions to the city.
The elephant has been at the zoo since 1990. The zoo hasn’t had any previous problems with its elephants, Cox said.
The zoo’s elephant matriarch, Connie, died last week, according to the zoo website.
The zoo opened as normal Friday, but the elephant exhibit was closed.
