Cannibalism
From Tardis Wiki, the free Doctor Who reference
Cannibalism was the eating of an animal, usually human, by one of its own kind.
The Brynblaidd cannibals killed and ate wanderers near their village every ten years. (TV: Countrycide)
At some point in Tennessee, there was a case of cannibalism, though the cuplrit claimed not to remember the crimes. (PROSE: The Juror's Story)
