I would be asking everyone old enough in the area about Ray and the possible story behind those.This going to sound like bs. But when i bought my first house (it was built in the 40s) we wouod always see dark spots around the ceiling from the corner of our eyes until we turned to look. The place was pretty creepy as well.
A few years in i decided to rewire the place. While working in the attic i found a pair of lineman pliers with no insulation on the handles. They looked to be from the 50s. They had also been blown up. A chunk was missing from the cutting edge from cutting into a live wire. They were engraved with the name ray.
I tossed the pliers. And i ran all the new wiring in metal conduit. Never seen anything afterward
