Maybe it was a case of theft in a business establishment. There could have been some employees involved, or it could have been an outsider who planned and executed the theft very cleverly. The story would then show how the police tracked down the thief, perhaps through surveillance footage or eyewitness accounts.
One possible scenario is a hit - and - run case. The victim was left on the road injured and the culprit fled the scene. The real story might focus on how the police used various means like vehicle parts left at the scene, or descriptions from bystanders to identify and catch the driver who was responsible for this callous act.
