Bizarre Calf Mutilations Found On Colorado Ranch

Is the US military testing more illegal bio-weapons on cattle?

A creepy string of calf mutilations in southern Colorado has a rancher and sheriff's officials mystified.

Four calves were found dead in a pasture just north of the New Mexico state line in recent weeks. The dead calves had their skins peeled back and organs cleared from the rib cage. One calf had its tongue removed.

But rancher Manuel Sanchez has found no signs of human attackers, such as footprints or ATV tracks. And there are no signs of an animal attack by a coyote or mountain lion. Usually predators leave pools of blood or drag marks from carrying away the livestock.

Two officers from the Costilla County Sheriff's Office have investigated the mutilations but say they don't know what's killing the calves.
