The first dead bull was found in a timbered ravine in eastern Oregon. There was no indication it had been shot, attacked by predators or eaten poisonous plants.
The animal’s sex organs and tongue had been removed. All the blood was gone.
In the next few days, four more Hereford bulls were found within 1.5 miles (2.5 kilometers) in the same condition. There were no tracks around the carcasses.
The theories range from scavengers such as carrion bugs eating the carcasses to people attacking the animals to cause financial harm to ranchers.
Residents speculate there could be UFO involvement. One person suggested that Jenkins look for craters underneath the carcasses, saying it would be evidence that the bulls had been levitated into a spaceship, mutilated, and then dropped back to the ground. Similar incidents in the past have also garnered UFO theories.
