Apparently the fact that elephants are endangered due to poaching isn't enough for some people, they feel the need to poison them as well.
At this stage the investigation isn't complete, and I hope to be able to find any follow-up articles to see if they can indeed confirm the poison hypothesis.
I'm sad to say that the idea that someone would poison an elephant for no understandable reason isn't as far-fetched as I would like. What I'd like to see is for further investigation to show that it was not poison, after all, which killed the elephant, but something more mundane, though no less tragic, like a heart attack. At least then I could continue to think better of my fellow apes.
