The material concerning the Animal Mutilation Project contains accounts of animal mutilations which were reported during the late 1970's. The FBI became involved when fifteen mutilations occurred in New Mexico. Various theories concerning the origins of the mutilations were explored by the FBI, including satanic cults, UFOs, pranksters, and natural predators. The investigation failed to identify any individuals responsible for the mutilations.
