SPRINGFIELD, MO (KYTV/CNN) - Zoo officials are trying to figure out what set off an elephant that charged and killed a zookeeper in Springfield, MO.
Police say 62-year-old John Phillip Bradford was in the Dickerson Park Zoo elephant enclosure with two other workers.
They had come to feed "Patience" the elephant when she charged Bradford.
The other two workers were unharmed.
"Police are still investigating all the details. They're interviewing co-workers. It's an extremely sad time for all the co-workers at the zoo and at the city," said Coretta Scott, spokesperson for the city.
Police say the elephant has been at the zoo for 23 years with no previous problems.
Bradford had worked there for more than 25 years.
