Cattle mutilation
Cattle mutilation (also known as bovine excision) is the apparent killing and then mutilation of cattle under unusual or anomalous circumstances. Sheep and horses have been allegedly mutilated under similar circumstances.
Key Points
Since the time that reports of purported animal mutilations began, the causes have been attributed variously to natural decomposition, normal predators, cryptid predators, extraterrestrials, secretive governmental or military agencies, and cults. “Mutilations” have been the subject of two independent federal investigations.
Reports of mutilated cattle first surfaced in the United States in the early 1960s when it was allegedly largely confined to the states of Pennsylvania and Kansas.
The phenomena remained largely unknown outside cattle raising communities until 1967, when the Pueblo Chieftain in Pueblo, Colorado published a story about a horse named Lady who was mutilated in mysterious circumstances, which was then picked up by the wider press and distributed nationwide; this case was also the first to feature speculation that unidentified flying objects were somehow associated with mutilation.
By the mid 1970s, mutilated cattle were reported in 15 states, from Montana and South Dakota in the north, to New Mexico and Texas in the south.
Democratic senator Floyd K. Haskell contacted the FBI asking for help in 1975 due to public concern regarding the issue. He claimed there had been 130 mutilations in Colorado alone.
Physical characteristics
Although the exact nature of mutilations varies from case to case, a typical mutilation might involve any or all of the following:
- The removal of eyes, udders and sexual organs
- The removal of the anus to a depth of around 12 inches
- The removal of the tongue and/or lips
- The removal of one ear
- The stripping of hide and flesh from the jaw and the area directly beneath the ear
- The removal of soft organs from the lower body
- The presence of incisions and cuts across the body that appear to have been made by a surgical instrument
- Unexplained damage to remaining organs, but no sign of damage to the surrounding area
- A lack of predation signs (including teethmarks, tearing of the skin or flesh, or animal footprints) on or around the carcass.
- Lack of scavenging
In most cases mutilation wounds appear to be clean, and carried out surgically. Mutilated animals are usually, though not always reported to have been drained of blood, and have no sign of blood in the immediate area or around their wounds.
According to sample FBI records from 1975, mutilations of the eye occurred in 14 percent of cases, mutilation of the tongue in 33 percent of cases, mutilation of the genitals in 74 percent of cases, and mutilation of the rectum in 48 percent of cases. According to a later survey taken by the NIDS mutilation of the eye occurred in 58 percent of cases, mutilation of the tongue in 22 percent of cases, the genitals in 85 percent of cases, and the rectum in 76 percent of cases.
According to Dr. Howard Burgess, nearly 90 percent of mutilated cattle are between four and five years old.
Some mutilations are said to occur in very brief periods. A 2002 NIDS report relates a 1997 case from Utah. Two ranchers tagged a specific calf, then continued tagging other animals in the same pasture. The ranchers were, at the most, about 300 yards from the calf.
Less than an hour later, the first calf was discovered completely eviscerated — most muscle and all internal organs were missing. There was no blood, entrails, or apparent disturbance at the scene. Independent analysts both uncovered marks on the calf’s remains consistent with two different types of tools: a large, machete-type blade, and smaller, more delicate scissors.
Laboratory reports
Laboratory reports carried out on some mutilated animals have shown unusually high or low levels of vitamins or minerals in tissue samples, and the presence of chemicals not normally found in animals. However, not all mutilated animals display these anomalies, and those that do have slightly different anomalies from one another. On account of the time between death and necropsy, and a lack of background information on specific cattle, investigators have often found it impossible to determine if these variations are connected to the animals’ deaths or not.
In one case documented by New Mexico police and the FBI, an 11 month old cross Hereford-Charolais bull, belonging to a Mr. Manuel Gomez of Dulce, New Mexico, was found mutilated on March 24, 1978. It displayed ‘classic’ mutilation signs, including the removal of the rectum and sex organs with what appeared to be a sharp and precise instrument and its internal organs were found to be inconsistent with a normal case of death followed by predation.
Both the liver and the heart were white and mushy. Both organs had the texture and consistency of peanut butter Gabriel L Veldez, New Mexico Police
The animal’s heart as well as bone and muscle samples were sent to the Los Alamos Scientific Laboratory, part of the University of California, for microscopic and bacteriological studies, while sample from the animal’s liver were sent to two separate private laboratories.
Los Alamos detected the presence of naturally occurring Clostridium bacteria in the heart, but was unable to reach any conclusions because of the possibility that the bacteria represented postmortem contamination. They did not directly investigate the heart’s unusual color or texture.
Samples from the animal’s liver were found to be completely devoid of copper and to contain 4 times the normal level of zinc, potassium and phosphorus. The scientists performing the analysis were unable to explain these anomalies.
Blood samples taken at the scene were reported to be “light pink in color” and Did not clot after several days while the animal’s hide was found to be unusually brittle for a fresh death (the animal was estimated to have been dead for 5 hours) and the flesh underneath was found to be discolored.
None of the laboratories were able to report any firm conclusions on the cause of the blood or tissue damage. At the time, it was suggested that a burst of radiation may have been used to kill the animal, blowing apart its red blood cells in the process. This hypothesis was later discarded as subsequent reports from the Los Alamos Scientific Laboratory later confirmed the presence of anti-coagulants in samples taken from other cows mutilated in the region.
Other signs
In addition to the physical aspects of the mutilation, ranchers commonly claim to find unusual signs upon or after the discovery of a mutilated animal.
- Unusual restlessness among surviving animals
- Refusal of predators and scavengers to feed on the mutilated carcass
- Strange marks or ‘post holes’ on the ground around the mutilated animal
- Unusual odors. Commonly described as being medicinal or surgical in nature.
Aliens and UFOs
Various hypotheses suggest cattle mutilations have been committed by aliens gathering genetic material for unknown purposes. Most of these hypotheses are based on the premise that earthly entities could not perform such clean dissections in such a short space of time without being seen or leaving evidence behind at the mutilation site, and around laboratory reports suggesting the use of unconventional cutting tools and other unexpected phenomena.
