For John Bender, his wife, and their two kids, murder was a family trade. From 1987 to 1983, the "Bloody Benders," as they've been dubbed in subsequent years, ran a general store and inn in Kansas, where guests would check in but, for the most part, never check out.

Allegedly, the Benders would invite a guest to have dinner with them and have the person sit on a chair that was positioned over a trap door. The wife would distract the guest long enough to give John time to bash them over the head with a hammer and one of their kids to slice the throat open. The trap door would then open, dumping the body into the cellar where someone would tend to it before burying the corpse somewhere near the orchard.
