Ever heard of The Servant Girl Annihilator? That's a pretty intense moniker. And some folks believe this Texas serial killer went on to become Jack the Ripper. This "annihilator" was also dubbed the Austin Axe Murderer, which is a little more catchy, but not quite as shocking. Some folks believe this uncaught killer was a man named Nathan Elgin, while other folks think the unknown killer sailed overseas to become Jack the Ripper. The Annihilator had a very clear pattern of murdering women. Each of the eight women he murdered suffered axe wounds to the head while they slept, then were moved from their beds into their yards and sexually assaulted. This spree of murders all happened in 1885.
