Several waves of cattle mutilation were reported in the end of the 20th century. A mysterious “predator” opened animal carcasses cutting out their internal organs. The predator was unstoppable and dead cattle were found even in zoos.
The most mutilations occurred in 1975 – 1976, the worst of them found in the US. There were thousands of victims. In Colorado alone three cows on average were mutilated on a daily basis. Governor Richard Lamm then stated that the mutilations were "one of the greatest outrages in the history of western cattle industry." Once, buffaloes were mutilated in Cheyenne Mountain that at the time hosted a US Air Force Defense Station. The predators were not stopped by thousands of soldiers patrolling the area. Bloodless animal carcasses remained the challenge that the Americans could not stand up to.
In 2009, cattle mutilators came back. On March 8, a dead cow was found near the Purgatoire River by Mike Duran, a cattle rancher.
"She's an older cow so I thought she may have died. … I spotted her near the (Purgatoire) river bottom and went and looked at her. She was on her side and it looked a little odd. When I took a closer look I saw that her udders had been removed," Duran said. It appeared as if the utters were cut off with a laser. There was no blood on or around the carcass and the incisions were perfectly round.
Two weeks later, Jim Garren, a rancher from Walsenburg, Colorado, also found a dead cow with its udders cut off.
"We searched and searched and we could not find blood on the ground or on the cow. I just can't understand how anyone could surgically remove a part from an animal and not spill some blood," he said.
Absence of blood is one of the characteristics of an invisible forces’ attack. After opening carcasses, veterinarians find out that there is not a single drop of blood in them. It is very difficult to bleed out an animal because when arteries are cut open, veins close and hold the blood back. The blood can be removed by pumping salt solution through arteries, but it is difficult to do in a field.
Rancher Tom Miller found one of his calves dead near a feed tub where cows congregate to eat twice daily.
"It's the strangest thing I've ever seen. I cut the hide and the legs just fell off. All the bones were broken," Miller said.
This happens when a mutilated animal is thrown down from above. There were a number of cases when ranchers found carcasses in the trees, hanging off power lines, or other places where a cow cannot get on its own. Traces of animals in the snow or mud would suddenly disappear as if the animals were lifted in the air. Coyotes and vultures would not touch the carcasses.
