CATTLE KILLERS

Something mysterious and violent is killing cattle of the North American plains, but what is behind these gruesome attacks -- satanic cults, an unknown predator, or something previously unknown to man? For 40 years, there have been thousands of cases of cattle found mutilated under abnormal circumstances; these livestock are found dead, often with their blood drained and organs or body parts removed from their bodies. Abnormally high radiation levels have been detected in the soil near the dead animals when they are found, and the deaths often do not match the pattern of known predators. With no apparent footprints or tracks leading to or from the carcases and strange circles near the site, the mystery only deepens. A MonsterQuest team will gather samples and head to a laboratory to scientifically analyze the most compelling evidence.
