Some Believe Aliens or 'North Vietnamese Army' Caused Mysterious Cattle Deaths in Oregon

Ranchers in the most remote parts of Eastern Oregon don't understand how or why so many cattle in the region have died through mutilation that includes surgical-like incisions, but not a trace of blood left behind.

Mysterious mutilations in Oregon have been documented for at least four decades. Cowboys have recently found purebred bulls all of a sudden dead, with body parts intricately removed, according to Oregon Public Broadcasting.

A similar thing happened in the Pendleton during the 1980s when rancher Terry Anderson had a mother cow whose udder had been removed with something razor sharp. The mystery?

"Not one drop of blood anywhere," Anderson said.

More than four hours south of Pendleton is Princeton, where a couple of years ago another cow was found dead — sliced up and mutilated, yet bloodless. Local residents made their rounds through the area looking for any clues or tracks that could lead to a conclusion, but they kept coming up empty. A local butcher even said he could not explain how it happened.

And this summer at the expansive 140,000-acre Silvies Valley Ranch, five young Hereford bulls were found dead, with their tongues and genitals removed and no tracks left behind.

When the ranch's vice president, Colby Marshall, drove the press to the location, they found a bull still laying dead on the ground, with a coat fresh and shiny enough for a county fair or market sale, and yet no flesh-feasting birds or other animals fighting for the carcass.

Marshall explained the sudden cattle deaths is mind-boggling, because finding such animals in remote locations, and in their prime and pulling off a traceless mutilation, seems unlikely.

"It's rugged," Marshall said. "I mean this is the frontier. ... If some person, or persons, has the ability to take down a 2,000-pound range bull, you know, it's not inconceivable that they wouldn't have a lot of problems dealing with a 180-pound cowboy."

Dan Jenkins is a sheriff's deputy in Harney County who has investigated cattle deaths, and he gets calls from people who say aliens could be involved.

"A lot of people lean toward the aliens," Jenkins said. "One caller had told us to look for basically a depression under the carcass. 'Cause he said that the alien ships will kinda beam the cow up and do whatever they are going to do with it. Then they just drop them from a great height."

Though aliens seem to be a popular opinion when there is no credible evidence found during investigations, it doesn't keep theories from pouring in.

"Another [person] told us we should run like a Geiger counter type thing around the animal and guarantees that there would be radiation there," Jenkins said. "And the number one on the list there, he thinks it's the North Vietnamese army."

National Geographic

National Geographic interviewed a rancher who claims to have seen a bright light in the sky one night before one of his cattle was mutilated with no tracks in the snow, nor a trace of blood. He believes aliens abducted his cow, took it into space, removed its genitals and dropped it back onto the property where they found it.

The Oregon massacre is nothing new. Christopher O'Brien tackled the issue of bloodless cattle mutilations happening worldwide for 50 years in his book Stalking the Herd: Unraveling the Cattle Mutilation Mystery.

Meanwhile on the other side of the world, researchers are trying to figure out how dozens of cattle and oxen in Kathmandu suddenly died while bleeding from every orifice in an anthrax-like attack.

From the Western United States to Southern Arizona and from the Deep South to farms in France, cattle have mysteriously died through mutilations, maulings and mystery.

Last year, 24 cattle were reported dead in Arizona over a span of a few weeks. Though originally ruled by the State Veterinarian's office the first two cattle had been shot, it was later reversed as lab results came in for more dead cattle, according to

The BBC reported this summer that cattle in France have either died or suffered low productivity because of "electromagnetic fields created by wind farms and electrical installations."
