SAN LUIS Manuel Sanchez tucks his leathery hands into well-worn pockets and nods toward a cedar tree where, last month, he found his fourth mysteriously slaughtered calf in as many weeks. "I have no idea what could do this. I wish I did," he says. Four calves, all killed overnight. Their innards gone. Tongues sliced out. Udders carefully removed. Facial skin sliced and gone. Eyes cored away. Not a single track surrounding the carcasses, which were found in pastures locked behind two gates and a mile from any road. Not a drop of blood on the ground or even on the remaining skin. http://www.denverpost.com/ci_13956752 This happened to my doctor's buffalo here in WY, too. Oddly, the snow underneath the beast wasn't melted. His opinion was that it was done with a laser. There was no blood in that case, either. Weird. I hope someone figures out what's going on.
