This is the 4th investigation at the video store for Doorways Magazine. We tried the new grid laser .We didn't get anything from that piece of equipment that we thought was paranormal. We did someting interesting results from the Led lights and like we always do when we go there, we heard plenty of loud noises. Not sure that the noises are paranormal, but we haven't been able to figure out the cause of them yet. One of the noises we did figure out was caused by the water heater in the restroom.
