So, some creepy places... your players could enter an underpass and when they come out on the other side, they've somehow come out in a basement. It's the basement of one of their homes, the home of one of the victims, or wherever they're staying.
They could be in the woods and slowly realize they're coming on a rock field (like Ringing Rock Park or a similar glacier field). They begin to notice very large boulders among the trees, taller than a man. Then they notice the boulders are evenly spaced, in a ring... and there is a very large stone slab at their center with red stains... As the clouds clear away from the moon, the light makes the rocks almost seem to move.
They come upon an abandoned quarry. The players notice footprints heading down the overgrown road. If they follow them, the trail leads into the water. There are no footprints coming back out. Maybe they notice what look like ominous dark caves along the water line and a faint tapping. They notice a frayed rope hanging from a nearby tree that hits the rock when the wind blows. They wrap it around one of the trees. The tapping gets LOUDER. hehe
You could also add "rake" sightings as seen very clearly in one of the episodes of Everyman Hybrid.
