To catch a predator: the wildlife detective helping ranchers and mountain lions coexist

Petros Chrysafis helps Californians like the wildlife they live with' by taking a unique approach to deterring livestock killings

Petros Chrysafis has always had a fascination with predators, but he never thought he could make a career out of it. Then he helped a friend solve a chicken-stealing coyote problem. Word spread. Now he runs a one-man predator detection and deterrence" business in California's Central valley and Sierra Nevada mountains.

His job is an odd combo of forensic scientist, homicide detective, set designer and negotiator. Typically when he first meets his clients, they are ready to find and kill the predator that's been attacking their livestock. His goal is to offer an alternative: coexistence.
