Disturbing calls used to come into game wardens with the Colorado Division of Wildlife. Headless deer and elk carcasses were being found in popular hunting areas. They were left by poachers who wanted the heads as trophies.So game wardens started a campaign to stop illegal hunting. That was two years ago, and they've been so successful the Division of Wildlife recently received an award for their efforts. Rob Firth is the division's chief of law enforcement. He talks to Ryan Warner.
