One day in the spring of 2006, a detective stood next to a refrigerator in her police station, holding a little container full of evidence. She knew that what she was about to do represented a breach of protocol – but that wasn’t going to stop her. Because she was working her first murder case ever, and she was afraid she wasn’t going to be able to catch the killer. She had decided she was going to run her case her way – no matter what. She was supposed to send the container in her hand to the state crime lab for analysis. But she wasn’t going to do that. Instead, she placed the container in the refrigerator, and then shut the door.
