On a cold winter day in 2013, police officers rushed through the dense woods outside of a small town in Kentucky. They weaved their way through the trees, keeping their eyes peeled, and finally, one of them shouted out. He saw what they were looking for in the distance. The other officers quickly followed him into a clearing, and there, they saw a man with a long gray beard sitting in a large self-made camp. It looked like the man had been living out in the woods for months. The officers stared at him, and they almost couldn’t believe it, because they had finally tracked down the man who they thought could help solve a murder that had taken place a year earlier in a town 150 miles away.
