On 30 June 2010 in Peoria Zoo, Illinois, a giraffe was eating leaves in it’s enclosure when its head and neck got caught in the fork of the tree. The animal struggled but couldn’t dislodge its head. Somehow the movements of the 15-foot-tall animal flipped its body causing further distress.
A keeper at the zoo said “It was just a terrible accident. We don’t know how he died but it seems less like a broken neck and more like a heart attack.” The keeper went on to say “They can be skittish animals.”
