Mary The Elephant (AKA ‘Murderous Mary’)

Considered the “largest living mammal on the planet” at the time and owned by Sparks Circus, Mary was a 5-tonne elephant who could play 25 tunes on the horns without missing a note. When an inexperienced drifter named Red Eldridge was hired to handle her in September 1916 in Kingsport, Tennessee, the elephant grabbed him with her trunk and stomped on his head. Eldridge died and in revenge the townsfolk demanded that the poor elephant be killed. Shooting failed so thus, in front of 2,500 people, Mary was hanged from a railroad derrick. A true indication of how depraved humanity can truly be.
