Deep in a forum discussion thread two years ago, I stumbled upon a comment regarding an abandoned mill in Grand Ledge, Michigan that was said to be haunted.
Unexplained bangs, voices, and odd feelings were supposedly reported there.
When we investigated the site... now a large stretch of land aside the railroad tracks... we were caught off guard by the level of activity documented, especially for such an obscure legend (we couldn't find anything else online describing any hauntings) at a location that you could hardly tell used to be an old mill (we had to have a local pizza delivery man point us in the right direction!)
Nonetheless, when we arrived at the property, we decided to place a digital recorder on the ground, leaving it by itself while we explored other areas. We put a flashlight next to it so we could easily find it again.
That's when the weird stuff began to happen.
We took out a K2 meter, and it began to spike. But every time it spiked, our flashlight blinked. For no reason. We have never seen this flashlight blink like this, and it was doing it in sync with the K2 meter. Then, we took out the spirit box, and we recorded three different voices that seemed to be discussing the K2 / flashlight activity. The first voice said "it's happening!" Then a voice said "I know." Then a third voice said "unbelievable." All while the K2 and flashlight were responding.
