'It's the stuff of high drama': Q+A with author and cattle mutilation investigator

It’s a strange case on the range after a cow was found mutilated on a farm near Calgary earlier this month. The gruesome death — the cow was missing her udder, vagina, uterus and a single eye — has spurred rumours of vigilantes, cults, exploding cattle and aliens in the hamlet of Madden, Alberta. Author Christopher O’Brien has personally investigated 200 American cases of cattle mutilation, and researched thousands more from around the world. He published a book about the strange occurences last year, following more than 20 years of research, called Stalking the Herd: Unraveling the Cattle Mutilation Mystery. O’Brien spoke to the Herald’s Annalise Klingbeil from his home in Arizona.
