Raccoon Predation on Domestic Cats

Raccoons are predators. They normally have a fairly omnivorous diet. They hunt small mammals, crayfish, frogs, and just about anything else they can catch. However, sometimes raccoons get into trouble with humans when they hunt our pets. In the case below, a raccoon killed and ate 16 barn cats over a couple months. I got an email from the cats' owner asking what animal could be the culprit. The photos below tell the story.
