Name: The Zookeeper
Weapon: Lions, Tigers, and Bears
Story: Kindly animal lover by day, demented psychopath by night, this once docile and caring caretaker breeds his exotic pets in the isolated mountains of Appalachia. Tucked neatly behind his mountain hideaway is a miniature menagerie of apex predators bought on the black market. Once he has settled on a victim, he quietly stalks his prey, waiting and watching them go about their daily lives. Unfortunately for his victims, a trailer meant for horses can be easily retconned for more... exotic passengers, and once the poor souls have left their house, perhaps for a nice dinner out or a romantic night on the town, the Zookeeper descends on their undefended domicile.
Slipping open a window or door, he coaxes his selected pet into the house of the unsuspecting victim with a morsel of meat. Nothing too big of course...
For the Zookeeper's plan to work, they'll need to keep up their appetite.
His part in the plan completed, the Zookeeper pulls back to watch events unfold from a safe distance. Minutes, sometimes hours later, the blissfully unaware homeowners return, strolling happily into their humble abode.
A jacket comes off... now a scarf.. and then they see it.
A flash of movement in the corner, a hiss from down he hall.
The zookeeper smiles as his hungry pet brutally mauls it's unsuspecting victim, quietly vanishing into the night.
