I've heard about claims like this...always figured this nuttiness was an urban legend. Turns out, some people really do think this way.
A rancher in Las Animas County, Colorado made a shocking and gruesome discovery over the weekend. He found a mutilated cow by the Purgatoire River.
Duran has a theory about what happened. "We have other life out there and I think that's what it is," said Duran.
Duran says he thinks aliens abducted the cow, carved it up and then dropped it back by the river. He doesn't have proof, but claims to have seen some strange sights in the Colorado skies above his ranch. "Like a round circle in the air," said Duran. "I've watched them and then they just disappear," he said.
