March 28, 2016 — Harambe the gorilla is shot and killed

Harambe was a gorilla living in the Cincinnati Zoo and Botanical Garden – where he had been for the previous two years – when a three year old boy somehow got into his enclosure. Harambe took hold of the boy and carried him around. His behaviour was not overtly hostile, but he was clearly becoming agitated by the crowd and zoo officials were concerned that the gorilla might become angered and hurt the boy – or even hurt him accidentally.

Harambe was killed by a single shot from a rifle, and the boy was rescued from the enclosure. The gorilla’s death became a highly divisive issue, with strong social media contingents for and against.
