Official Investigations into Cattle Mutilation — Federal and State Responses

The cattle mutilation phenomenon has generated multiple official investigations at federal and state levels, none of which have reached conclusions satisfying all parties. The most significant federal investigation was conducted in 1979-1980 by retired FBI agent Kenneth Rommel, funded by a $44,000 grant from the Law Enforcement Assistance Administration. Rommel examined 15 alleged mutilation cases in New Mexico and concluded that all could be attributed to natural predation, scavenger activity, and decomposition. His report was embraced by skeptics but rejected by ranchers and other investigators who argued Rommel's sample was too small and his methodology biased toward conventional explanations. State-level investigations in Colorado, Montana, and Oregon similarly concluded that natural causes were responsible, though investigators in each state acknowledged cases they found difficult to explain. The disconnect between official conclusions and the observations of ranchers, veterinarians, and local law enforcement who examined the carcasses firsthand has fueled persistent distrust of official explanations and sustained interest in alternative theories.
