I use it to provide clues to the PCs. A Perception check might let you know how a someone was killed a DC 15 medicine check might reveal that puncture how has a lingering traces of poison around it and a DC 20 or 25 roll might reveal what type of poison it is. Were those slashes made by claws or a weapon? Those burn marks could be a bonfire or some type of breathe weapon? A high roll could also reveal what type of breathe weapon such as a red dragon.
