According to center officials, one of the lions left a locked space and went where workers were cleaning the enclosure, quickly killing one worker. WTVD reported that the lion was shot and killed so county personnel could get to the worker, whose name was not released. The family of the victim has not been notified yet, according to WTVD.

It is not clear how the lion got out. An investigation is ongoing and the center, which is typically open to the public, is closed until further notice.
