Kate Bender, Bender Family -- Kansas
The Benders : Keepers of the Devils Inn $7.95 - The book describes
a series of murders perpetrated in the early 1870s by the four members
of the so-called Bender family. The murders were committed at a
roadside inn, on the prairie, nine miles from Cherryvale, Kansas.
As travelers would stop by for a bite to eat, they would be seated
in front of a curtain behind which "Kate Bender" would smack them on
the head with a hammer. They would be robbed and their bodies would
be dropped through a trap door in the inn floor. Later the bodies
would be buried in the back yard. The travelers would just "disappear"
and their families were unable to find them. About 50 people were
killed before people started getting suspicious.
