In April 1979, facing a persistent wave of reports of cattle found dead with 'surgical' cuts, missing blood and soft tissues —and recurrent attributions to UFOs, black helicopters and cults—, Senator Harrison Schmitt (NM) convened a federal conference in Albuquerque. The FBI, local prosecutors, NM Attorney General Toney Anaya, veterinarians and ranchers attended. The political conclusion was clear: an investigation with executive authority was needed, not more folklore.

The DOJ's Law Enforcement Assistance Administration (LEAA) approved a grant of approximately USD 44,170 to the 1st Judicial District Attorney's office (Santa Fe) to conduct the investigation. The DA hired Kenneth M. Rommel —retired FBI agent with a 28-year career, no stake in the UFO debate— as project director. For twelve months, Rommel and his team responded to every fresh report they could reach in NM, ordered formal veterinary necropsies in state laboratories, interviewed ranchers, sheriffs, veterinarians and witnesses of lights, and reviewed prior files.

The investigation, launched in May 1979 and conducted over roughly a year, was structured around five formal objectives, among them: determining the reliability of the information on which the grant request was based, establishing the cause of as many mutilations as possible —particularly those in New Mexico— and determining whether cattle mutilations constituted a serious law-enforcement problem. On April 15, 1980, Rommel held a press conference previewing his conclusions, ahead of the formal delivery of the report.

The final report, 'Operation Animal Mutilation: Report of the District Attorney, First Judicial District, State of New Mexico', was delivered to the DOJ in June 1980. Its 297 pages examine 15 cases in detail. In each, necropsies documented death from known natural causes —difficult birth, disease, clostridium, lightning, loco weed intoxication— followed by normal predation by coyotes, dogs and scavenger birds that consume soft tissue first (eyes, tongue, anus, genitals), which are also the most exposed parts and the least protected by the animal's extremely tough hide. The 'surgical cuts' result from the combination of small-carnivore bites, post-mortem lividity that drains visible blood from the area, swelling and skin tension from decomposition gases that, when it tears, produces clean-looking edges, and desiccation of those edges in dry climate. Rommel noted that his findings matched those of sheriffs and pathologists in other states. He explicitly ruled out cult intervention, covert military helicopters and clandestine federal agents: he found no instruments, no witnesses of operations, no physical traces compatible with those hypotheses.

The report's reception illustrates why a skeptical case does not automatically settle a cultural debate. Senator Schmitt himself, who had pushed for the investigation, gave it only qualified support: he said the report was 'fairly well written', but that it 'certainly doesn't answer all of the questions'. For part of the cattle-mutilation research community, a sample of 15 cases in a single state was too narrow to generalize to a phenomenon reported across much of the American West; for others, the agreement among necropsies, pathologists and documented predation made the report the reference explanation. The corpus records both positions, but acknowledges that the evidentiary asymmetry favors Rommel: the natural hypothesis is supported by necropsies and pathology, whereas the anomalous hypotheses rest on inference from the appearance of the carcasses.

El Informe Rommel es el contrapeso institucional más fuerte del corpus para una categoría entera de fenómeno. No es un OVNI 'desmentido'; es una clase completa de anomalía —mutilaciones de ganado, presentes en folklore, prensa y cine desde los 70— sometida a investigación federal con autoridad judicial, financiamiento DOJ, metodología veterinaria estándar y un director sin sesgo previo. La conclusión es nítida y verificable: el patrón es natural. Esto vale más que cualquier opinión escéptica individual porque cumple los criterios que el corpus exige para los casos pro-anómalos: documento primario, autoridad institucional, metodología reproducible. Tier S precisamente porque la rigurosidad metodológica es simétrica con la que se exige a los casos que pesan en la otra dirección. Si Colares 1977 es Tier S por la investigación FAB, Rommel 1980 es Tier S por la investigación DOJ.

The Rommel Report is the strongest institutional counterweight in the corpus for an entire category of phenomenon. It is not a single UFO 'debunked'; it is a whole class of anomaly —cattle mutilations, present in folklore, press and film since the 70s— subjected to federal investigation with judicial authority, DOJ funding, standard veterinary methodology and an unbiased director. The conclusion is sharp and verifiable: the pattern is natural. This is worth more than any individual skeptical opinion because it meets the criteria the corpus demands of pro-anomalous cases: primary document, institutional authority, reproducible methodology. Tier S precisely because the methodological rigor is symmetric with what is demanded of cases that weigh in the other direction. If Colares 1977 is Tier S for the FAB investigation, Rommel 1980 is Tier S for the DOJ investigation.
