Two years ago, in the middle of the night, a fire broke out in a commercial building on the northern edge of the city of Dallas. It destroyed a small yogurt company called Three Happy Cows.
Two months later, Edgar Diaz, the founder of Three Happy Cows, confessed that he'd set the fire. Yet people who knew Diaz, and had worked with him, could not believe it.
"I was like, Edgar did that? No way! No way. No way," says Ruth Cruz, who worked at Three Happy Cows.
"No. No. It was his baby. Couldn't imagine," says Don Seale, who supplied milk to the factory.
