This is just bizarre: rather than admitting that their managers screwed up by exposing animals to disease, they claimed that they killed a 31 year-old Asian elephant this morning because he was pushed into a moat and suffered damage to his left leg, and then claimed that they had "immediately redesigned the facility." That's an outright lie.
First, they did nothing to the facility for many years. Second, they killed the elephant because he was not responding well to drug treatment for management-caused tuberculosis infection. It was, after all, upon their orders that the animals were exposed.
