In nearly any Crime and Punishment Series, by the end of the episode, someone will always be heading to the coroner's office, no matter how things start out. Generally, the vast majority of episodes will be about a killing straight through, from beginning to end. It'll either be a straight up murder or perhaps a burglary gone wrong, but by the time our heroes are on the scene, there's a dead body and someone out there to answer for that. But that's not all. In the other episodes, when the show will start out investigate a missing person or a heist or something, someone will inevitably end up dead halfway through, killed by one of the perpetrators of the original crime (or the victim, or the detective, or the witness's twin brother's sister-in-law, etc.). It's a law of nature.
