Ryan Easley cared for the big cats at the Growler Pines Tiger Preserve in Choctaw County. A statement from the preserve confirmed Easley died after an “accident involving a tiger under his care.” The statement said he was a conservation advocate, dedicated to the animals’ protection.

A large tiger fatally attacked an animal handler as horrified onlookers watched during the end of a big cat show at a preserve in southeastern Oklahoma, officials said Monday.

Animal rights groups reacted to news of Easley’s death with calls to end the use of wild animals in performances.
